EDITORIAL
W elcome to our fi rst copy of Lubezine for
the year 2014. Our team wishes you a
prosperous year ahead as we usher in
another exciting year in which we will
bring you incisive and comprehensive lube
reports, analyses and technology updates,
particularly those affecting the African continent.
Maintenance trends are changing globally, with maintenance
programs now shifting from the so-called run-to-failure and
preventive maintenance to condition-based maintenance. The
condition-based scheme allows maintenance personnel to care-
fully schedule plant shutdown and address the specifi c machinery
problems that had, prior to the shutdown, been detected via CBM
techniques.
As far as lubricants and lubrication is concerned, the key
condition-based maintenance technique commonly used is oil
analysis. In this edition, we elaborate in detail how this technique
fi ts seamlessly into the overall CBM program. We have particu-
larly focused on how this technique is applicable to transformer
maintenance in our cover article.
Our regular contributor, Mr. Baraka, excites an interesting
debate on the environmental impact of using of recycled base
oils in the formulation of lubricants. His aptly titled ‘Mitumba’
(Second Hand) lubricants make for a both insightful and interest-
ing read. Our Last Word column provides a Kenyan sales and
marketing executive’s perspective on marketing lubricants.
Sales executives are always at the front end of any business as Mr.
Ndaka argues in his article.
Tanzania is one of the most important lubricants market in the
East African region. We have reports of the steps being under-
taken by the Tanzania Bureau of Standards (TBS) in regulating
that market. Counterfeit lubricants continue to hurt lubricants
business in many African countries. But with such stringent steps
as those taken by TBS, this malpractice can be controlled. We
gratefully thank our loyal advertisers, professional contributors,
including our 3,000-plus strong readership outreach. Thanks to
your unwavering support, Lubezine Magazine continues to be the
premier source of lube information in the region. .Welcome

LUBRICANTS CONFERENCE
T he 2nd ICIS African
Base Oils & Lubricants
Conference took place
at the Southern Sun Cape Sun
Hotel in Cape Town on 6th and
7th November. The event drew
crowds from a number of top
chemicals companies, including
ExxonMobil, Engen, Chevron,
Petronas, Lubrizol, Total, and
PetroSA, providing a leading
platform for identifying and
establishing further insights
into the various markets
associated with base oils and
lubricants across Africa.
Anthony Lawrence, Research
Analyst for the Chemicals, Mate-
rials & Foods (CMF) unit at Frost
& Sullivan, delivered a presenta-
tion focused on identifying key
African Mega Trends infl uenc-
ing both the automotive and
industrial lubricants markets on
the African continent.
Mega Trends not only open
up substantial opportunities
to companies on a global level,
but they also signifi cantly alter
the competitive structure of the
industries in which companies
operate, and the players within
them.
“In the competitive landscape
in South Africa, fi ve tier one
petrochemical companies hold
between 80 and 90 percent of
the industrial lubricants market.
These companies include Shell,
Chevron, Engen, Total and
Castrol,” noted Lawrence. “

that synthetic lubricants has in
improving energy effi ciency
He also expanded upon the
drivers growing energy demand
across Africa, and how synthetic
lubricants will be able to address
fuel effi ciency whilst facilitating
in the reduction of emissions.
It was noted that the market
for synthetics is becoming an
even greater opportunity for
many petrochemical compa-
nies, traders and the like.
David Gamble, Senior
Tribologist and Technical
Support to Supply Chain from
Anglo American, provided
the audience with in-depth
knowledge of the different types
of machinery used in mining,
which accurately put volumes
consumed within the mining
sector into perspective.
He later elaborated on areas
that may present themselves
as future opportunities for new
suppliers of lubricants within
the market.
Gamble also pointed out that
country government pressures
are on the increase and it is
becoming more apparent that
mining ventures should look
to buying products from local
suppliers. It therefore seems
apparent that joint ventures,
agencies, and distributors may
be the route to take in terms of
the supply of lubricants. .

T anzania last December
launched its testing
machine that will be
used to test lubricants and oil
products , previously tested by
the Kenya Bureau of Standards
in Kenya.
Deputy Minister for Trade
and Industries, Mr. Gregory
Teu, told the Daily News,
ahead of the launch, that the
machines will not only relieve
Tanzania from the cost of
sending samples to Kenya, but
will also ensure the products’
quality authenticity.
Mr. Teu said the machine
had already arrived at the
Tanzania Bureau of Standards
(TBS) and was awaiting instal-
lation to be ready for operation
early in 2014.
“We have good news for
manufacturing, automotive
and transport industries - we
have procured our own plant
for testing lubricants and oil
products instead of sending the
samples to Kenya as was the
case before. The move will be
of great economic advantage to
our country,” he said.
The new development
came hot on the heels of the
country’s recording of another
achievement by installing a
state-of-the-art machine at TBS
for fuel testing, which was also
previously done in Mombasa,
Kenya.
TBS Principal Standards
Offi cer, Mr Nickonia Mwabuka,
told the Daily News during the
Tanzania Automotive Exhibi-
tion that machines and engines
in the country might have
short life spans due to the kind
of oils and lubricants applied.
He said local manufactur-
ers and transporters should
always consult the Bureau
when in doubt of the qual-
ity of oil products they are
using, otherwise they risked
damaging their machines.
Although of late the problem
of substandard lubricating
materials has largely been
curtailed, Mr Mwabuka was of
the view that extra care should
be taken as there were reports
of substandard products still
being smuggled in through
unoffi cial routes.
He said when using quality
lubricants and oil a motor vehi-
cle engine has the capacity of
running for between 8000 km
to 10,000km instead of 5000km
as was currently the case.
“Many machines will last for
only half of their expected life
span if they keep on consum-
ing substandard lubricants. It is
high time the trend changed so
the industry could realise value
for money spent to maintain
the machines,” he said. .
MOTORISTS should now think twice before buying engine oils, or any other forms of lubricants following discovery of presence of substandard engine oils, brake fluids and other forms of lubricant products scattered across the country.
It was just in a span of a day since the Tanzania Bureau of Standards (TBS) issued a public warning on the presence of the inferior lubricants when one
City dealer Ms Zib Enterprises saw its godown being closed down yesterday for keeping the products suspected to have been imported from the United Arab Emirates (UAE).
According to the TBS Principal Standards Off icer Mr Nickonia Mwabuka, of late the Bureau has come across rampant importation and supply of inferior lubricants which is extremely dangerous to life of motor vehicles engines.
“Our inspectors carried out market surveillance and discovered that Zaib Enterprise was involved in supplying substandard oils and lubricants,” he alleged, adding: “We have now closed it down for more investiga-tions and actions according to the law.
TBS off icials and the police had to ensure tight security and close supervision as the godown, situ-ated at Vingunguti area in Ilala
Municipality was being closed down and sealed with heavy duty lockers.
As an exercise to nab more other importers and suppliers of the substandard products has been off icially launched, TBS has warned all dealers and motorist to be careful when purchasing and changing oils and lubricants for their vehicle engines or else incur massive loss. .Source: Daily News TZ

FAQSSmall players gain lubricants market share

Why should one use special oil for limited slip diff erentials?It is important that one uses
limited slip differential oil
for limited slip differentials. When one is
driving on uneven surface condition like
mud, the power distribution between
two drive shafts is not equal as more
power is shifted to the wheel with less
resistance. This causes the wheel to
slip. Limited slip differentials are able
to effectively lock the two half shafts,
ensuring equal power distribution.
When this limited slip differentials are
used, high shock loadings occur on the
clutch system in the differential which
may cause wear and slipping. The use of
incorrect oils can lead to clutch degrada-
tion and vibration.
Can I top up engine mineral oil with a synthetic oil and vice versa? Yes it is okay. The synthetic
fl uids (polyalphaolefi ns) used in engine
oils are man made or lab made formats of
mineral oil and are therefore compatible
with mineral oils. In semi-synthetic
formulations, mineral oils and synthetic
oils are mixed in different proportions
in the formulation. Main disadvantage
when topping up using synthetic oil is
that the synthetic oil is expensive and
one will be negating the benefi ts it would
provide if used alone like good cold start,
good high temperature performance and
long drain intervals.
Should I use pre-mixed or concentrate cool-ant?The main issue here is that a
premixed coolant is used as
is, while a concentrate will require one to
dilute to the recommended proportions.
It is required that one uses de-ionized
water to dilute the concentrate in order
to derive the required performance of the
coolant. The pre-mixed coolant already is
diluted using the de-ionized water.
De-ionized water free of dissolved miner-
als is required for use in coolant since
minerals and particulate making it ideally
suited for use in coolants
What does API GL mean?API stands for American
Petroleum Institute and GL
stands for Gear Lubricant. API
is the body mandated to license engine and
gear lubricants. For the gear oils see below
the defi nitions:
• API GL-1 Straight mineral oil.
• API GL-2 Mild EP for worm gear oils.
• API GL-3 Mild EP for spur and spiral
bevel gears in axles and transmissions.
• API GL-4 Medium EP, moderate severity
hypoid gears, manual gearboxes.
• API GL-5 High EP, all hypoid axles,
some manual gearboxes.
• API GL-6 Extra high EP, now obsolete. .
minerals contribute to scale formation,
which impedes effi cient functioning of
the coolant system, leading to a failure. All
global coolant specifi cations and standards
have quality requirements for the water
appropriate for use in a coolant product.
Piped or bore hole water can contain
appreciable amounts of dissolved minerals
and fi ne particulate and is not recom-
mended to dilute coolant concentrate for
this reason. De-ionized water has been

T here has been a
marked increase
in lubricants
manufactured from
recycled base oils
in the East African
market. The lubricants
are imported either as
finished lubricants
or base oil which are
then blended locally
to produce harmful
lubricants. Most of
these base oils and
lubricants originate
from the United Arab
Emirates. The lubri-
cants manufactured
from recycled base oil
are 20 to 30% cheaper
than products manu-
factured from virgin
base oils but they
promise to be an envi-
ronmental time bomb.
Base oils are the major component in a
fi nished lubricant consisting between 80 and
99% of the fi nished product. The balance is
chemical additives that are added to enhance
the performance and these are added at the
recommendation of the additives manufac-
turer to meet pre-determined international
specifications such as those of American
Petroleum Institute (API) and the original
manufacturers’ equipment requirements.
The Kenya Bureau of Standards reacted
to the infl ux of the substandard lubricants
by setting the minimum specifications for
lubricants, a move that has been taken by
the other East African authorities of quality
standards. The result is the collective decision
to set minimum specifi cation for lubricants
as follows:-
• API CD for diesel engines
• API SF for petrol engines
However, even with this attempt, these
specifi cations are obsolete at least according

“Mitumba” lubricants, an environmental catastrophy
to the American Petroleum Institute’s latest
engine oil specifi cations in addition to other
recently set up standards. The East African
lubricants set market standards are therefore
low. They are supposed to give a minimum
drain interval of 3000 to 5000 kilometers. If
drain intervals are over extended, the life of
equipment is reduced significantly due to
increased engine wear.
For a lubricant to achieve any standards,
the additive producer develops the additive
which is blended into a lubricant that is
tested in various engines. Typically these
products are made from virgin base oils in
order to qualify for the specifi cation. Prod-
ucts made from re-cycled base oils cannot
qualify under any international standards.

P.22from used oils. Large users of lubricants have
serious problems of disposal of the used oils
they generate. As a result, the used oils are
collected and stored in vertical tanks and
thereafter they are subjected to vibration and
fi ltration to remove the solid particles which
include carbon. The base oils do not undergo
any chemical change and so contain the
cancer causing properties of used oils. Other
dangers include impurities like glycols from
brake fl uid and engine coolants, transformer
oils, gear oils and additives that are used in
grease which might include lead.
The impurities in each base oil batch vary
from one batch to another depending on the
source of the used oil. It is for this reason they
cannot be used for formulating quality lubri-
cants as the quality of the fi nished lubricant
cannot be predicted.
Furthermore, some of the impurities inter-
fere with the performance of the lubricants.
For example, glycol will make the fi nished
lubricant thicken faster than a similar prod-
uct made from virgin base oils.
Of major concern is that the mitumba base
oils are industrial wastes. And according to
the Basel convention signed in 1992, these
base oils should not be transferred across bor-
ders without approval of the receiving coun-
try at the request from the exporting country.
The Basel convention further advocates that
such hazardous material be used at the source
country as fuel materials in cement kilns.
The Basel convention by the United
Nation’s Environmental Program (UNEP) was
initiated when it was discovered that devel-
oped countries were increasingly disposing
their industrial waste in under-developed
countries who until recently did not fathom
the grave effects of recycled base oils.
This begs the question: Why are we still
importing substandard and harmful base
oils? First off, they present a cheaper option
for consumers who dare to use these base
oils since they are 30 to 40% cheaper than
the virgin base oils. Other beneficiaries of
this harmful trend are the blenders who are
making handsome profi ts at the expense of
genuine industry players. The reality is how-
ever, that it is all is false economics as far as
the end-user is concerned. Whereas a product
of equal quality made from virgin base oil can
give you a drain interval of X kilometers; the
product made from recycled base oil will give
you 1/3X kilometers. This means the end-user
uses 3 times more oil and 3 times more fi lters,
all these are disposed of in the environment
eventually contaminating both ground and
underground water.
As they say 1 liter of used oil contaminates
1 Million liters of water. With Kenya being
a water stressed country, there’s no doubt
that recycled base oils are a real threat to the
increasingly scarce water sources.
A good example is the use of recycled base
oils in lubricating the power saws chains that
are used in the forests which are the main
water catchment areas. Because these oils are
poorly formulated and cheap, the usage is
very high further exposing the water sources
to increased risk of contamination.
These oils increase maintenance costs as
well as reducing the life of equipment. This
reduction in equipment life means frequent
machine repair and replacement of spare
parts, which translates to slower production
and subsequently higher operating costs.
Ultimately the equipment will end up in the
scrap yard prematurely.
From the foregoing Kenya and Africa in
general should be wary of increased dump-
ing and use of recycled base oils in view of the
damages they cause to human health, equip-
ment and the environment. It is important
that Government regulatory bodies’ step up
more aggressively and monitor the type of
base oils used in lubricants production.
The good news is that Kenya’s Bureau of
Standards is working on new standards to
check on the quality of base oils imported into
the country. This will defi nitely go a long way
in sealing all the loopholes currently facilitat-
ing the importation of the harmful base oils.
The anticipated result will be reducing the
dangers posed to the environment, human
health and animals as well as save industry
players a coin or two. .
The Kenya Bureau of Standards reacted to the influx of the substandard lubricants by setting the minimum specifications for lubricants, a move that has been taken by the other East African authorities of qualitystandards.

What is Condition Based Maintenance (CBM)
Di f f e r e n t
s c h o l a r s
have defi ned
Condition
Based Maintenance
(CBM) in different ways.
Some indicate CBM also
as predictive mainte-
nance. In general, CBM
is a technology that
strives to identify incipi-
ent faults before they
become critical which
enables more accurate planning of the preventive
maintenance.
The main purpose of CBM is to reduce the
cost of performing corrective maintenance
on systems and equipment by requiring
corrective/restorative maintenance actions
only when the deterioration of the system or
equipment justifi es the maintenance action.
Condition Based Maintenance (CBM) bases
maintenance need on the actual condition of
the equipment or machine and not any preset
schedule. This differs from the preventive
maintenance, which is time-based and activi-
ties such as changing a lubricant which are
also based on time.
For example, most car owners change the
engine oil every 5,000kms. Here there is no
checking of the actual condition and perfor-
mance capability of the oil. If the car owner
had his used oil analyzed to determine the
actual lubricant condition and properties, he
may be able to extend the oil change to more
kilometers say 10,000 kms.
This is the vital core differentiator that
predictive maintenance is used to define
needed maintenance task based on quanti-
fi ed equipment condition. It uses the actual

PREDICT IVE MAINTENANCE
Lubricant oil analysis as a Condition Based Maintenance technique
systems to optimize total plant operation. A
comprehensive predictive maintenance man-
agement program utilizes a combination of
the most cost-effective tools like:
i) Thermography
ii) Vibration monitoring
iii) Oil Analysis
iv) Ultrasonic technology
Central to the CBM policy is the use of con-
dition monitoring (CM) information for plan-
ning and scheduling maintenance routines.
Condition monitoring involves observing
some component or system condition-related
variables throughout the asset’s lifetime.
Thus the degree of deterioration or degrada-
tion is determined more accurately.
CBM is the most desirable scheduling
option where asset failure has high conse-
quence, when periodic observation is possible
and practical, and when it is the cost-effective
option.
Lubricants oil analysisOne of the basic technologies of condition
based maintenance (CBM), is lubricating oil
analysis. The reason for this is that lube oil
analysis is a very effective tool for providing
early warning of potential equipment prob-
lems. The goals of oil monitoring and analysis
are to ensure that the parts requiring lubrica-
tion are lubricated properly.
This occurs by monitoring the condition of
both the lubricant and the internal surfaces
that come in contact with the lubricant. Some
plants maintain their own oil analysis labo-
ratories, while others send the samples to a
recognized laboratory outside their plants.
The outside laboratories normally produce a
very comprehensive independent report, in
a very short time, and at an affordable cost.
As lubricant and machine conditions
deteriorate, the physical properties, chemical
properties of the oil, wear and contaminant
levels will change. By monitoring and trend-
ing these changes in a given time, setting

and equipment problems or potential failures
can Identifi ed fast and resolved.
A vital component in understanding and
determining the exact cause of oil-related fail-
ures or problems is the ability to identify and
classify the types of wear and contaminants
present as well as knowing their suspected
source. This exercise will require an under-
standing of physical and chemical properties
of the lubricants being used, the type of metals
used in the internal components within the
equipment where lubricants are used, and
the various sources of contamination that
can enter the system internally or externally.
Wear and contamination can be classifi ed
in four different categories:
System wear or contamination System generated wear or contamination can
be a combination of ferrous and non-ferrous
particles that are generated from the parts
of the equipment like bearings, rings, seals,
and other internal components that come
in contact with the lubricant. Abrasive wear
from metal particles and other contaminants
circulating in the system, metal surface
fatigue, loss of film thickness or strength,
and other fault conditions can be detected by
analyzing the used oil.
Information regarding the amount, size,
and types of particles is required, in order to
determine what component in the system
is wearing, how severe the condition is, and
what corrective actions may be required.
Typical elements monitored to assess the
13 November 2013-January 2014 | LUBEZINE MAGAZINE
amount of system or internal wear present
include: iron, copper, tin lead, aluminum,
chromium, silver nickel, titanium, and anti-
mony.
Particles generated from system wear con-
tamination pose the following dangers:
• The particles are mostly abrasive to the
metal surfaces they come in contact with.
• They may also chemically interact with
the oil itself, causing the formation of
sludges and gums. These will corrode
metal surfaces, deplete additives, and
accelerate the chemical breakdown of the
lubricant.
• Smaller particles pass through the bearing
clearances and contact areas, cutting away
at the metal surfaces they come in contact
with. This results in the damage to the
metal surfaces, fatigue, and the generation
of new particles that will be introduced
into the system.
• In some cases these particles may also
imbed themselves in the metal surfaces.
This creates a surface anomaly that acts as
a cutting tool against the opposing bearing
surface.
Contamination from external sourcesContamination from airborne particulates
(dirt, coal dust, organics), process fluids
(Freon, acids), and other external processes
are another source of contamination that
can affect lubricant and machine condition.
These contaminants typically enter lubrica-
tion systems from the outside environment
through breathers, fill/vent plugs, access
covers, and other entry pathways.
Typical parameters monitored to assess the
amount of external contamination present
include Fourier transform – infrared spectros-
copy, and elemental levels of silicon, sodium,
boron, and potassium.
WaterOne of most common and damaging sources
of contamination is water/moisture. Even at
low levels, the presence of water will corrode
metal surfaces (rusting), increase oxidation,
and reduce the oil fi lm strength which leads
to increased wear. There are a variety of
sources where water can come from cooler
leaks, seal leaks, condensation and pathways
into the lube oil system through breathers,
access covers, vents, and other opening.
Water may exist in three different states;
1) Free water, 2) Emulsifi ed water and 3) Dis-
solved water.
It is important to understand the source of
water ingression, so that adequate corrective
actions can be taken to eliminate the problem.
Water is one of the most harmful con-
taminants that can affect lubrication systems
since it degrades both lubricant and machine
condition.
Water poses the following dangers to the
system:
• Water will increase the rate of oxidation,
and deplete additives through the process
of hydrolysis.
• Insoluble acids are created that cause cor-
rosion of the metal surfaces, pitting, bear-
ing fatigue, and the generation of abrasive
rust particles.
• The rust particles accelerate machine wear
as they act like catalysts.
• The acids also breakdown the chemical
properties of the lubricant. This leads to
the formation of sludge and varnish.
• Large amounts of water can lower viscos-
ity and reduce fi lm thickness, to the point
where metal-to-metal contact may occur.
The end result is inadequate lubrication
and reduced bearing life.
Products from degradation of lubri-cants Lubricants are formulated and manufactured
with high quality base stocks and additive
packages. The additive package causes the
lubricant to withstand chemical degradation
or breakdown during normal operation. As
the lubricants are used, they age and due
to the presence of heat and oxygen, they
also undergo oxidation, additive levels are
depleted and eventually insoluble acids and
oxides are formed. As insoluble acids accu-
mulate, the viscosity of the lubricant will
increase, causing greater fluid friction and
an increase in operating temperatures. These
high temperatures will increase the rate of
oxidation and the chemical breakdown of
the lubricant.
This process is accelerated under abnormal
conditions such as high operating tempera-
tures, water contamination, air entrainment,
and excessive machine wear. The oxidation
deposits may harden and adhere to the
surfaces causing lacquering. In hydraulic
systems where the lubricant is utilized as a
medium, the sludge may block the system as
well as cause erratic operation of the system.
Typical parameters that are monitored to
evaluate the chemical breakdown of lubri-
cants and oxidation include:
• Fourier transform (infrared spectroscopy).
• Total acid number (TAN).
• Elemental levels of zinc, phosphorous,
barium, calcium, magnesium, and molyb-
denum in parts per million (ppm).
Lubricant oil analysis plays a vital part
in evaluating contamination levels and
managing the condition of the lubricant
and machine components. Setting threshold
limits for lubricant properties, contamina-
tion, wear metals and measuring actual
equipment performance against these limits,
abnormal conditions can be quickly identi-
fi ed and resolved before internal equipment
or component damage occurs.
Two areas key in machinery lubrication
are the condition of the lubricant and the
condition of the surface lubricated. These two
issues can be found from the lubricant sam-
ples extracted from the lubrication system.
This yields important information about the
internal machine condition.
ConclusionWith lubricant oil analysis as part of the
CBM policy in any plant, equipment avail-
ability can be enhanced, unplanned repairs
avoided, scheduled downtimes incorporated
and better asset management attained in the
whole life cycle of the asset. These eventually
leads to longer useful life of the equipment,
better returns and lower operating and main-
tenance costs which directly improved the
plant economics. .

INFORMATION SOURCE
2-stroke motorcycle engine oilsNotwithstanding the environ-mental regulations, there are millions of 2T motorcycles and scooters in use around the world.
2T engine oil specifications have been developed to allow adequate protection against piston and cylinder scuff ing, ring sticking, exhaust blocking and reduction in smoke levels which arises from the need to alleviate smoke problems in urban environments. 2T motorcycle engine oil specifications have been developed to address these issues to aid the optimisation
and formulation of 2T engine oils.
4-stroke motorcycle engine oilsGlobal environmental and emission regulations have seen a move from two-stroke (2T) engines to four-stroke (4T) engines in the motorcycle market. As such four-stroke motorcycle lubricant specifica-tions and requirements are diff erent from those of 2T and also diff erent from passenger car engine oils. 4T engines have very high power, run at high revs and high temperatures. 4T clutches need
special friction properties to balance clutch slip versus clutch snatch and the engine oil is important for cooling the clutch plates. Gearboxes are compact and the gear sets narrow. Small size, high engine power and typically air-cooled design can lead to oil shear, gear scuff ing/pitting and higher thermal loading. 4T motorcycle engine oil specifications have
been developed to address these issues to aid the optimization and formulation of 4T engine oils.
Motorcycle Engine Oil (MCO) Industry stand-ards The established and most widely recognized industry standards for MCOs are summarized in the table below:

designed for today’s modern passenger car
engine are used in motorcycles. However,
these applications have contrasting lubri-
cation needs that make the use of dedicated

OIL ANALYS IS
How a cost-efficient oil analysis programme can prolong transformer life
It is well known
t h a t r e g u l a r
oil analysis is
extremely useful
in monitoring the
condition of engines,
drive trains, hydrau-
lics, turbines and
many other types of
oil-lubricated equip-
ment. The same can
be said for trans-
former oils, which are
used to insulate many transformers and other
electrical distribution equipment. The analy-
sis of transformer oils not only provides infor-
mation about the oil, but enables the detection
of other potential problems, including contact
arcing, ageing insulating paper and other
latent faults. It is also an indispensable part of a
cost-effi cient electrical maintenance program.
Failure riskTransformer maintenance has evolved
over the past 20 years, from a necessary
item of expenditure to a strategic tool in the
management of electrical transmission and
distribution networks. Extreme reliability is
demanded of electric power distribution, and
even though the failure risk of a transformer
and other oil-filled electrical equipment is
small, when failures do occur, they inevitably
lead to high repair costs, long downtime and
very real safety risks. Moreover, transformers
are too expensive to replace regularly and
must be properly maintained to maximise
their life expectancy.
By accurately monitoring the condition of
the oil, many types of faults can be discovered
before they become serious failures and out-
ages can potentially be avoided. Further, an
efficient approach to maintenance can be
adopted and the optimum intervals deter-
mined for replacement. Some of the checks
are relatively simple: the operation of the
gas relays, the operation of the on-load tap-
changer, checks on oil leaks, and so on.
However, breakdown of one of the most cru-
cial elements, the oil / paper insulating system,
can only reliably be detected by routine oil
analysis. By measuring certain physical and
chemical properties of oil, in addition to the
concentrations of certain dissolved gases, a
number of problem conditions associated
with either the oil or the transformer can be
determined.
Moisture ContentOne of the most important functions of trans-
former oil is to provide electrical insulation.
Any increase in moisture content can reduce
the insulating properties of the oil, which may
result in dielectric breakdown. Water and oil,
due to their differing chemical properties are
not mutually soluble. However, up to a certain
limit, a small amount of water will dissolve in
the oil. This limit is a function of the tempera-
ture of the system and the solubility increases
exponentially with increasing temperature.
This is of particular importance with
fluctuating temperatures because, as the
transformer cools down, any dissolved water
will become free, resulting in poor insulating
power and oil degradation. A point to note is
that, as the oil ages in service, a certain amount
of oxidation occurs, which changes the chemi-
cal make-up of the oil, in turn allowing more
water to dissolve.
In addition, many transformers contain
cellulose-based paper used as insulation in
the windings. Excessive moisture content can
result in the breakdown of this paper insula-
tion with a resultant loss in performance.
The moisture content of the oil is determined
using Coulometric Karl Fischer. This is an
extremely sensitive test and can detect water
at levels down to a few parts per million.

Because transformer oils are designed to provide electrical insulation under high electrical potentials, any
significant reduction in the dielectric strength will indicate that the oil is no longer able to perform this vital function.
former, a high power factor is an indication
of signifi cant power loss in the transformer
oil, usually as a result of contaminants such
as water, oxidised oil and cellulose paper
degradation, but may also be any substance
in the oil that either resists or conducts elec-
tricity differently to that of the oil itself and
may include diesel fuel, lubricating oil and
kerosene. The test is not specific in what it
detects and is usually carried out at elevated
temperatures as contaminants that affect the
test may remain undetected at 25ºC and only
reveal themselves at >90ºC.
Interfacial Tension (IFT)The interfacial tension of transformer oil is
related to its deterioration. Transformer oil is
generally a hydrocarbon and thus hydropho-
bic; however, when the sample undergoes
oxidative degradation, oxygenated species
such as carboxylic acids are formed, which
are hydrophilic in nature.
Interfacial tension is the surface tension of
a sample of the oil carefully fl oated on top of
a layer of water. The more hydrophilic the oil
becomes, the lower the value of the surface
tension between the two liquids.
Studies have shown that there is a defi nite
relationship between acid number and IFT,
an increase in acid number generally shows a
decrease in IFT, however when there is a loss
in IFT without the corresponding increase in
acid number, it is generally because of contam-
ination with another hydrophilic substance
not derived from oxidation of the oil.
Furanics (or degree of polymerisation)The solid insulation (cellulose-based prod-
ucts) in transformers degrades with time
at rates which depend on the temperature,
moisture content, oxygen and acids in the
insulation system. Heat and moisture are the
main enemies of the solid paper insulation
with oxidation as the primary culprit. When
degradation occurs, the cellulose molecular
chains (polymers) get shorter and chemical
products such as furanic derivatives are pro-
duced and dissolve in the transformer oil. Of
the furanic compounds, the 2-furaldehyde is
the most abundant.
Its concentration in oil has been related to
the degree of polymerisation (DP) and conse-
quently to the physical strength of the solid
Acid NumberJust like lubricating oils, transformer oils are
oxidised under the influence of excessive
temperature and oxygen, particularly in the
presence of small metal particles, which can
act as catalysts. Oxidation products are usu-
ally acidic in nature and result in an increase
in acid number.
Further reaction of these acids with the bulk
oil can result in sludge and varnish deposits.
In the worst-case scenario, the oil canals
become blocked and the transformer is not
cooled adequately, which further exacerbates
oil breakdown.
Furthermore, an increase in the acidity has
a damaging effect on the cellulose paper. Oil
degradation by-products, such as acids and
hydroperoxides, also generally have the abil-
ity to conduct an electrical charge, which in
turn reduces the insulating properties of the
oil. An increase in Acid Number often goes
hand-in-hand with a decrease in dielectric
strength and increased moisture content as
shown in Figure 1. Again, just like their indus-
trial cousins, the acid content of transformer
oils is determined by Potentiometric titration
with potassium hydroxide.
Dielectric StrengthThe dielectric strength of a transformer oil
is a measure of the oil’s ability to withstand
electrical stress without failure. Because trans-
former oils are designed to provide electrical
insulation under high electrical potentials,
any significant reduction in the dielectric
strength will indicate that the oil is no longer
able to perform this vital function. Some
of the things that can cause a reduction in
dielectric strength include contaminants such
as water, sediment, conducting particles, oil
degradation by-products and cellulose paper
breakdown.
The test method for determining dielectric
strength is relatively simple and involves
applying an AC voltage at a controlled
increasing rate to two electrodes immersed
in the transformer oil. The gap is a specifi ed
distance and when the current arcs across this
gap the voltage recorded is used to determine
the dielectric strength.
Power or Dissipation FactorThe power factor of transformer oil is the
ratio of true power to apparent power and is
a measure of the current leakage through the
oil, which in turn is a measure of the contami-
nation or deterioration of the oil. In a trans-

insulation. (See fi gure 2).
Indefinite lifeThe cellulose materials are the weakest link
in the insulation system. Since the life of the
transformer is actually the life of the cellulose
insulation and degradation of the cellulose
is irreversible, the decay products should
be removed before they can do any further
damage to the cellulose.
With proper maintenance, the cellulose
can virtually have an indefi nite life. To test
for furanics, a sample of the oil is obtained
and certain chemical techniques are used to
extract the furans from the oil. The extract
is then analysed using a process called high
performance liquid chromatography (HPLC).
The results are usually reported in terms of
parts per billion (ppb).
Dissolved Gas Analysis (DGA)The analysis of gases from petroleum products
has been performed for decades using gas
chromatography. However, this technique
was not applied specifically to transformer
mineral oils until the late 1960s/early 1970,s
and is now commonly called dissolved gas-in-
oil analysis (DGA).
DGA has become a standard in the electrical
maintenance industry throughout the world
and is considered to be the most important oil
test for transformer oils in electrical appara-
tus. More importantly, an oil sample can be
taken at any time from most equipment with-
out having to take it out of service, allowing a
“window” inside the electrical apparatus that
helps with diagnosing and trouble-shooting
potential problems.
As the insulating materials of a transformer
break down from excessive thermal or elec-
trical stress, gaseous by-products form. The
by-products are characteristic of the type
of incipient-fault condition, the materials
involved and the severity of the condition.
Indeed, it is the ability to detect such a
variety of problems that makes this test such
a powerful tool for detecting incipient-fault
conditions and for root-cause investigations
after failures have occurred.
Dissolved gases are detectable in low
concentrations (ppm level), which usually
permit early intervention before failure of
the electrical apparatus occurs, and allow for
planned maintenance. The DGA technique
involves extracting or stripping the gases from
the oil and injecting them into a gas chroma-
tograph (GC). Typical gases generated from
mineral oil / cellulose (paper and pressboard)
-insulated transformers include: Hydrogen,
H2; Methane, CH4;Ethane, C2H6; Ethylene,
C2H4;Acetylene, C2H2;Carbon Monoxide,
CO and Carbon Dioxide, CO2.
Additionally, oxygen and nitrogen are
always present, their concentrations vary
with the type of preservation system used on
the transformer. Also, gases such as propane,
butane, butene and others can be formed as
well, but their use for diagnostic purposes is
not widespread.
The concentration of the different gases pro-
vides information about the type of incipient-
fault condition present as well as the severity.
For example, four broad categories of fault
conditions have been described and character-
ized in Table 1.
The severity of an incipient-fault condition
is ascertained by the total amount of com-
bustible gases present (CO, H2, C2H2, C2H4,
C2H6, CH4) and their rate of generation.
Generally, transformers will retain a large
portion of the gases generated and therefore
produce a cumulative history of the insulating
materials’ degradation.
This is an important tool for detecting and
trending incipient problems. However, it also
means that care is needed in interpreting
values for a fi rst-time analysis on service-aged
transformers (more than several years old),
which could contain residual gases from
previous events.
Abnormal behaviour Some gas generation is expected from normal
ageing of the transformer insulation and it is
therefore important to differentiate between
normal and excessive gassing rates. Normal
ageing or gas generation varies with trans-
former design, loading and type of insulating
materials. Routinely, general gassing rates for
all transformers are used to defi ne abnormal
behaviour. Specifi c information for a family
of transformers can be used when suffi cient
dissolved gas-in-oil data are available.
Acetylene is considered to be the most sig-
nifi cant gas generated. An enormous amount
of energy is required to produce acetylene,
which is formed from the breakdown of oil at
temperatures in excess of 700°C.
Excessively high overheating of the oil
will produce the gas in low concentrations.
However, higher concentrations are typically
symptomatic of sustained arcing, a more seri-
ous operational issue that can cause a trans-
former failure if left unchecked.
DGA is used not only as a diagnostic tool but
also to stem apparatus failure. Failure of a large
power transformer not only results in the loss
of very expensive equipment but it can cause
signifi cant collateral damage as well. Revenue
losses due to operational outages may be the
least worrisome consequence of a failure.
Replacement of that transformer can take up
to a year if the failure is not catastrophic and
can result in tremendous revenue losses.
If the failure is catastrophic, then addi-
tional losses could be realised, such as adjacent
transformers, environmental problems from
the release of oil, (which could be as much as
20,000 litres), and the resulting fi re that must
be contained and smothered.
In order to avoid such a failure, the sample
frequency of most large power transformers is
between one and three years.
However, sampling frequencies will
increase as an incipient fault is detected and
monitored. Often sampling frequencies are

however, these tests are susceptible to false
positive results, since the test does not detect
PCB itself.
Specifi c methods utilise some type of chro-
matography to separate PCB molecules from
each other and interfering compounds. It is
not a case of simply fi nding an easily quantifi -
able compound, but of quantifying a complex
mixture of compounds. Of the three major
chromatography types, gas chromatography
(GC), thin layer chromatography (TLC) and
liquid chromatography, GC is the preferred
and most extensively-used method.
PCB terminology Any fl uid, including that in electrical equip-
ment and any item, which has a measurable
PCB concentration of less than 50ppm of
PCB, is considered a non-PCB item. Any fl uid,
including that in electrical equipment, and any
item which has a measurable PCB concentra-
tion of 50ppm or greater but less than 500ppm
is regarded as being PCB contaminated. Addi-
tionally, any fl uid, including that in electrical
equipment and in any item, which has a meas-
urable PCB concentration equal to or greater
than 500ppm, is regarded as a PCB item. It is
important to note that transformer oil that
has not been tested must be classifi ed as PCB
contaminated until shown to be otherwise.
Once the PCB status is determined, a sticker
is issued and fi xed to the item in question. This
allows for quick reference and ensures that
potential cross-contamination is avoided
during future sampling, maintenance and
decommissioning if necessary. Blending PCB
contaminated oil with virgin or other oil to
meet the legal requirements is obviously an
illegal practice that has been shown to happen
from time to time. This practice simply has the
effect of contaminating virgin oil supplies and
ensures that the PCBs persist in the environ-
ment and leads to further contamination.
Proper transformer sampling.Just like machinery oil analysis, the abil-
ity of transformer oil analysis to provide an
early warning sign of a problem condition
is dependent on the quality of the oil sample
that is sent to the lab. A sampling point on any
equipment should be identifi ed and clearly
labelled for the technician.
As with sampling locations in other types of
equipment, the same location should be used
each time a sample is collected to ensure rep-
resentative conditions are tested. This point
should be located in a place where a live oil
sample can be collected rather than in an area
where the oil is static.
Just like machinery oil analysis, electrical
transformer oil analysis can play a vital role in
preventing unscheduled outages in electrical
transmission and distribution equipment by
determining the condition of the equipment
itself, and other vital components, including
the condition of the oil and the cellulose paper
insulation. For all critical oil-fi lled electrical
equipment, including transformers, circuit
breakers and voltage regulators, regular, rou-
tine oil analysis should be the cornerstone of
any PM program. .
dictated by insurance requirements, which
often stipulate that annual transformer oil
analysis must be conducted to ensure contin-
ued coverage.
PCB analysisPCBs (polychlorinated biphenyls) are a group
of synthetic oil-like chemicals of the organo-
chlorine family. Until their toxic nature was
recognized and their use was banned in the
early 1980s, they were widely used as insula-
tion in electrical equipment, particularly
transformers. Three types of PCB are normally
used in electrical transformers: Aroclor 1242,
1254 and 1260 and commonly known by
various brand names. These include Askarel,
Chlorectol, Elemex, Inerteen, and Pyranol.
One of the most important problems with
PCBs is that they concentrate in the fatty parts
of microorganisms. This concentration factor
between the organism and the water can be
as much as a million times. Concentrations
are further amplifi ed, as the microorganisms
become food for animals further up the food
chain. PCBs are very stable and their degrada-
tion process is slow, making for yet greater
amplification in organisms. Although not
overly toxic in themselves, PCBs are poisons,
which have been shown to cause damage to
the reproductive, neurological and immune
systems of wildlife and humans.
Far more serious are the risks of a fi re or an
explosion. At temperatures around 500ºC,
extremely toxic compounds - polychlorinated
dibenzofuranes (PCDF) and polychlorinated
dibenzodioxins (PCDD) - are formed. Small
amounts of these compounds have been
found at accidents where transformers and
capacitors have been exposed to fi re or have
exploded. Even if the amounts have been
extremely small and have caused no personal
injuries, it has been necessary to perform very
extensive and costly decontamination work.
PCDDs and PCDFs cause damage and death
in doses as low as 1ppb to 5000ppb. Damage to
organs such as liver, kidney and digestive tract,
miscarriage, sterility can occur, and are some
of the most potent cancer promoters known.
Methods of PCB AnalysisCurrent methods of analysis are divided into
two major groups: PCB Specifi c and PCB Non-
specifi c. Non-specifi c methods test for PCBs
indirectly by detecting one of the components
of the PCB compound, usually chlorine. In
general, non-specific methods are quicker
and less expensive than the specifi c methods;

One of the most important functions of transformer oil is to provide electrical insulation. Any increase in moisture content can reduce the insulating properties of the oil, which may result in dielectric breakdown.

GREASES
Fresh trends in grease manufacturing processes seek to improve performance
Definition of GreaseThe American Society for Testing and Materi-
als (ASTM) defi nes grease as ‘a solid to semi
fl uid product of dispersion of a thickening
agent in liquid lubricant. Other ingredients
imparting special properties may be includ-
ed’. Grease is a lubricant which has been
thickened to ensure that it remains in place
during operation of the equipment; it should
remain in contact with moving surfaces and
not be slung off by the centrifugal forces
and not leak out under gravity. Greases are
used where a mechanism can only be lubri-
cated infrequently and where a lubricating oil
would not stay in position.
Generally greases contain 70-95 per cent of
base oils, 5-20 per cent of thickening agent,
and 0-10 per cent of additives. The main
classifi cation type of greases is depending on
the type of thickening agents. Some of the
main classifi cations are as follows include:
The lubricants market in Africa is estimated to be about 1.8 million tones, out of which 3 per cent – or about 55000 tones – is estimated
to be grease demand. These statistics underline the importance of grease, which has often been neglected in the fi eld of Tribology throughout the continent. In the recent past, grease has gained importance due to the main unique characteristics that make it advantageous to be used instead of liquid lubricants.

Calcium, Lithium, Titanium, Sodium, Alu-
minium , Clay, Polyurea and others.
The other major classification type
involves the use of consistency as depicted
by the NLGI (National Lubricant Greasing
Institute) as below:
Lithium Grease Manufacturing ProcessLithium-based grease is generally manu-
factured using two methods: Batch or Con-
tinuous process. Batch process is usually
preferable due to the numerous benefits it
has over the continuous process.
The basic elemental ingredients for a
lithium based grease production are Base
Oils: different grades for different applica-
tions; thickener: depending upon application
different type of soap or non soap thickener
will be used; additives: depending on appli-
cation many different additives can be used,
such as anti oxidation, anti wear, EP and solid
additives.
Batch Manufacturing Process:The ingredients in this process are metered or
weighed in bulk into the processing reactor,
where the process of saponifi cation occurs.
Saponifi cation is the process of forming soap
by splitting a fat with an alkali. The fat, alkali
and some base oil are added to the reactor.
The reactor is then heated up to about 150oC
to 250oC and mixing occurs. During this
process, the fat is converted to soap which is
dispersed throughout the mixture. The pro-
cess can be done in closed pressure kettles or
open kettles.
The next process is dehydration, where
water is removed from the mixture before
going to the next step of milling and homog-
enization.
The homogenization or milling process
is vital as it works on the structure of the
grease, giving it a uniform crystal and gel-
like structure that remains intact when in
use. This is very important because it will
produce a uniform crystal and gel structure
that will not change as the grease is used.
Homogenizing the grease breaks down the
solid particles or fi bers, disperses the resultant
small particles in the liquid by breaking up
lumps and eliminates graininess, producing
a smooth product.
The process can reduce the penetration
value of some types of grease by stiffening
it, while it can also improve the texture and
appearance. This process is carried out at
slightly lower temperatures than saponifi ca-
tion of about °C , after which the grease is
further cooled and packaged.
Please note that there are many methods
that can be followed depending on the type of
grease and the equipment available.
Continuous Manufacturing Process:The fat, alkali and some base oil are added to
the reactor for saponifi cation to take place.
The reactor mainly is tubular in structure.
The temperature is maintained up to 180°F.
In the tubular section, the fl ow velocity pro-
duces high turbulent fl ow. It is recommended
to minimize the water injected into the grease
with the additives. Temperature of the reac-
tion mixture which comes out of the saponi-
fi cation zone is maintained in the range of
about 100-200°C. A temperature of about
200°C is suffi cient to provide the necessary
amount of heat to such combined mixtures.
The temperature of the combined mixture
should not exceed the melting point of soap
component of the grease. Additional heat is
imparted to the combined mixture in heating
means to restore or increase the temperature
of the combined mixture to about 120°C and
to prevent condensation of water.
The dehydration section is usually main-
tained as a vacuum, which receives the

One of the
r e s o u r c e
p e r s o n s
at a training I
attended a while
ago observed that
perhaps the best
way to explain
something is to
start by stating
what it is not. I
agree with him to some extent.
But alive to the diffi culty that may be
involved in starting from describing what
viscosity is not, without getting into a
conundrum, I will start by saying what
it is. Considering the basic elements that
explain viscosity, the most basic defini-
tion of viscosity is the measure of a fl uid’s
resistance to fl ow.
And so on viscosity, including all the
derivatives that come from that word, at
the back of your mind I would want you to
have a mental perception of viscosity as
resistance to fl ow. Or – to put it in another
way – a liquid’s resistance capacity to fl ow.
Viscosity is arguably the most impor-
tant property of a lubricant, holding many
other factors constant, and depending on
the perspective from which you look at it.
In a discussion I initiated within a group
on Linked In , there was a wide range of
views on what viscosity is – and what it is
not. Contributing to the discussion, Toby
Taylor described viscosity as a physical
feature that sadly does not describe what
the oil is used for.
Excessive TechnicalityWhile Taylor’s assertion is true, it also
highlights a fundamental lubricant-user
information gap, based on the standard
descriptions used by oil companies world-
wide to describe lubricant application pur-
poses. Understanding viscosity would go a
long way to aid the public’s understanding
of lubricant applications, away from oil

mixture and water vapour and settles for
about half an hour. The grease mixture is
recycled continuously from the bottom of
the dehydration zone with the pressure up
to 10-200 psi. Base oil is added in the grease
mixture at lower temperature to enhance
cooling, after which it may be packaged.
Grease TrendsThere are several trends which are affect-
ing grease market. Years ago, we had a
slight shift from soda-based grease to cal-
cium.Today, the majority of grease in use is
Lithium based. The market is, however, wit-
nessing a shift to calcium sulphonate due
to global scarcity of lithium and the good
performance of this calcium sulphonate
soap. Shift to polymer and synthetic base
oils are also taking place across the world.
In additives, there is a slight movement
toward such novel metals as bismuth,
which are more environment-friendly than
Zinc ,with better synergy with Sulphur type
additive especially for EP grease. On market
side, the market is unfortunately suffering
from lack of knowledge and information
transfer as well as price sensitivity. These
are the main drivers for selecting grease
which have also infl uenced an increase in
circulation of cheap grease made by non
suitable soap , besides recycled base oils
into the market. This compromised quality
greases are corrosive and non suitable for
machineries.
One other trend is the growing accept-
ance of transparent type of grease which
is now available in the market. Whilst
transparency does not imply any premium
quality, the grease can have equal perfor-
mance with general grease, if manufactured
the right way, with its advantage being high
aesthetic value. .

marketers’ intricate descriptions by use of
excessive technicality with an aim limited
to marketing lubrication products.
Viscosity at the point of lubrication is
the most important of the specifi cations
but not the only consideration. You
cannot isolate this one important factor
and ignore the rest, because a lubricant
will interact with a dynamic environment.
Earlier, I mentioned the term Viscom-
etry which is the Science of measuring
viscosity. In other words, of or relating
to the measurement of viscosity. Viscos-
ity can be measured in terms of Absolute
Viscosity (Centripoise cPs), resistance to
fl ow and shear or by Kinematic viscosity
(Centistoke cSt) resistance to fl ow by shear
forces of gravity.
Viscosity with TemperatureThis brings me to the next viscosity
derivative: Viscosity Index, a measure of a
lubricant’s change in viscosity with tem-
perature. Normally, viscosity decreases
with increase in temperature and vice-
versa. Don McNeil stated in the Linked
In discussion, that this behaviour is
defi ned as an arbitrary number assigned
as a measure of the constancy of the
viscosity of lubricating oil with change
of temperature, with higher numbers
indicating viscosities that change little
with temperature.
It is simply a scale to indicate the viscos-
ity change of oils relative to temperature.
23 November 2013-January 2014 | LUBEZINE MAGAZINE
Improver – to boost this property.
Analysis AngleIt is a topic that can go on and on without end.
But looking at it from the oil analysis angle,
Greg Livingstone states in the continuing
discussion that although viscosity may be the
most important quality of oil, it does not mean
it is necessarily the most important property to
measure in an oil analysis program. ‘Oil analy-
sis tests should be based on the failure mode
of the lubricant and in many applications,
viscosity does not change, providing limited
value in condition monitoring.’ He observes.
There is no need to build a high structure
without a fi rm foundation. More importantly,
if you get the wrong viscosity, it means you
defi nitely have to deal with a myriad of other
issues. .
plays a major role in the choice of lubricant
base oil when formulating a lubricant because
the type of base oil to be used has to be pre-
determined based on the output required. That
sets the starting point of additivation.
Too much viscosity generates additional
fl uid drag, which further leads to an increase in
power requirements and increase in operating
temperature. At the same time, too low viscos-
ity can result to lots of leakage, metal-to-metal
contact, reduced pressure in a closed system
etc. Low viscosity oils can be used primarily for
low loads, low temperatures and high speeds.
Viscosity is a feature influenced by tem-
perature, contaminants, water and chemical
changes, pressure and shear. While viscosity is
a balancing act (neither too high nor too low), a
high viscosity index is preferred. Blenders go a
step further to even use an additive - Viscosity
An arbitrary scale for lubricating oils that is
used to indicate how much the viscosity of the
oil varies according to its temperature.
In general, viscosity informs how you
choose a base oil. Andrew Monk opines that
‘viscosity is and always will be the most impor-
tant criteria for selecting oil’. He adds: ‘If you
get that drastically wrong then no amount of
additives will ever compensate’.
That is a true statement, with the under-
standing that the formulation of a lubricant
involves blending base oil with the different
additives, depending on the fi nal requirements
of a product. There is need for suffi cient viscos-
ity to maintain lubricant fi lm strength. Viscos-
ity Index, according to Mr Monk, plays a part if
wide temperature variations are experienced,
but not too critical otherwise.
It is also in order to also state that viscosity

As more and
more compa-
nies continue
to expand due to
market demands,
production targets
and goals have to be
met and exceeded.
Fierce competition
also demands that an
organization reduces
its cost of production
in order to remain
competitive.
This however, is
not happening due to
frequent unplanned
shutdowns caused by
equipment failure.
These failures are
mainly attributed
to poor lubrication
practices.
Modern and effi cient maintenance methods
require less reliance on manual lubrication
activities. Production requirements and
modern equipment can no longer be managed
manually and therefore the need to automate
lubrication. Additionally, safety concerns
increase the need to automate.
Principle of AutomationAutomated Lubrication Systems also referred
to as Centralized Lubrication Systems
comprise of a controller or timer, pump,
grease or oil reservoir, metering valves and
fi ttings and supply and feed lines. The system
delivers a controlled amount of grease or oil
periodically to multiple lube points on a
machine while it is operating. Whether the
equipment is stationary or mobile such as
mining and construction equipment, appli-
cation of the lubricant is often most effective
when it is dispensed in small, measured
quantities over short, frequent time intervals.
Benefits of Automated Lubrication1. All critical components of the equipment
are lubricated
2. Lubricant is distributed evenly in the
bearing thereby increasing machine avail-
ability
3. Less wear of the components means
extended equipment life, fewer failures,
reduced downtime, reduced replacement
costs and reduced maintenance costs
4. Measured amounts means no wasted
F E A T U R ET E C H N O L O G Y
IndustriesCentralized lubrication systems are to be
found in many industries such as;
- Cement & Aggregates
- Food & Beverage
- Glass Manufacturing
- Mining
- Paper & Pulp
- Power Generation
- Steel
- Water & Waste Water
- Wind Energy
Total Cost of failuresAlthough bearings are just a part of the equip-
ment components, their failure results in the
failure of other components such as seals,
impellers and shafts. This means that indirect
failures are often much more than the bearing
failure itself. Installation of automated lubri-
cation systems hence becomes extremely
essential and not an option for manufactur-
ers and equipment owners looking to reduce
operating costs and increased production. .

5. Increased safety as access to dangerous
areas is not required
6. Reduced energy consumption due to less

7. Increased overall production due to
machine availability and reduced down-

Capital Cost of a SystemThe capital cost of a lubrication system
includes:
- Lubrication pump and fi ttings
- Piping system
- Engineering of the system
- Installation and commissioning
System Operating CostsOperating costs of the system include:
- Maintenance of the system which is
typically low as most components are
self-lubricated
- Lubricant costs which is essential but

a value-led approach, be it in our world-class

edge technical innovation or market-leading
products.”
ExxonMobil and BP follow with 10% and
7%, respectively. While Shell is expected to
remain among the market leaders in the imme-
diate future, it is the middle pack—regional
majors and NOCs—that are anticipated to see
the most changes, with companies like Fuchs
and Gazprom expected to claim some market
share from the top fi ve leaders. In 2012, for
example, Fuchs fi nds itself within the global
top ten for the fi rst time.
With the lubricant demand being slug-
gish worldwide, Group I base oils have
been mostly squeezed out of automotive
lubricants, particularly in North America,
by low-sulfur content mandated reformula-
tion trends and increasingly cost-effective
Group II alternatives. Consequently, Group I
producers are being impelled to focus more
on the industrial sector despite the competi-
tion from low-cost naphthenics and Group
II oils in some applications. As a result, the
proportion of Group I stocks in global base oil
consumption has been falling steadily from
around 70% in 2000 to 54% in 2012, and it
is expected to continue declining to approxi-
mately 30% by 2030.
A combination of increasingly stringent
emission and fuel-consumption norms, more
exacting OEM specifications, and volume
allowing a more attractive cost-proposition,
are among the leading factors promoting an
increased market share of synthetic and semi-
synthetic alternatives.
Although presently satisfying a modest
demand, regulations in Europe — and
increasingly in North America — are support-
ing growth in the re-refi ning sector. Already
strong basestock prices prior to the recession
caused a signifi cant interest in re-refi ned base-
stocks. With OEMs generally not objecting to
the use of re-refi ned basestocks, as long as the
quality and performance of the fi nal product
meets its specifi cations, astute marketing and
consumer education are key to realizing this
stream’s signifi cant potential.

Understanding Your ProductIs your lubricant blended from 100 per cent
virgin base oil or from recycled base oil or
ratios of both? Some lube companies are
marketing a brand that is blended from 50/50
or 75/25 mixtures of virgin and recycled and
then presenting the fi nished product to the
market as blended from 100% virgin base
oils. Without this important knowledge, the
salesman goes to the client clueless on where
his lubricant started.
In addition, basic knowledge of lubricant
additives and the specific roles they play
during the operation of the machine or vehi-
cle it is applied in is imperative. Such infor-
mation as SAE grades and API classifi cations
should be at the fi ngertips of any serious lube
salesperson. Knowing what a specifi c grade of
a lubricant is for and its particular application
is key. Understanding if your lubricant is min-
eral or synthetic is also an important detail
that one dealing in the sales and marketing
of lubricants should know.
Understanding Your BrandWhat is your brand’s unique Selling Proposi-
tion (USP), otherwise known as Unique Sell-
ing Point? What distinguishes your brand
requirements of any market. For example,
some grades of lubricants perform differently
from others based on climatic conditions like
temperatures. A SAE 50 grade of engine oil
will not perform well in a low temperature
location.
The buying behaviour of your target buyer
is also a factor to be considered seriously by
the salesperson before initiating the sales
process with the buyer. How is the creditwor-
thiness of your prospect?
You may need to ask around and if possible
try to get trade references from businesses that
have done business with the prospect before
you sign up the customer for credit. Delayed
payments increase the cost of credit in the
long run. This is in addition to the emotional
pressure, time wastage and possible legal
costs associated with chasing bad debtors.
Finally, seek to understand the potentials
and opportunities that exist in your area of
operation. As a marketer your employer is
counting on you to identify and manipulate
opportunities that will drive up sales while
bringing in healthy profi ts for the organisa-
tion. Automotive lubricants resellers (distrib-
utors) move big volumes but smaller margins
compared to direct sales to big transporters,
from the rest in the market? USP is defi ned
as the factor or consideration presented by a
seller as the reason why his product or service
is different or better than the competition.
Before you can begin to sell your product or
service to anyone else you need to sell your-
self on it fi rst.
This is especially important when your
product or service is similar to those around
you. In the petroleum sector, very few prod-
ucts are a one-of-a-kind and having unique-
ness in how you present your brand to the
buyer is very critical.
Unless you can pinpoint what makes your
business unique in a world of homogenous
competition you cannot target your sales
efforts successfully. A product can peg its USP
on product characteristics, price structure,
placement strategy (location and distribu-
tion) and promotional strategy. These are
what marketers call the 4P’s of marketing.
They are manipulated to give a business a
market position that sets it apart from the
competition.

Lubricants sales is no doubt one of the most complex sales processes in petroleum trading, what with the endless list of types of lubrication oils, greases and fl uids not forgetting their very detailed technical specifi cations, physical and chemical characteristics and applications. In this regard, knowing your product is very
important if you as a salesperson are to represent your brand in the market positively. A potential client needs to hear a presentation from somebody who seems to know more about lubricants than he does himself. There are important questions that should be answered in understanding a lubricant.

tory supervisor and know your
company’s delivery arrangements
beforehand.
And don’t tell a customer that you
will deliver goods in three hours if
you are not even sure you can deliver
in twelve! You are better off giving a
longer period of delivery and deliver-
ing in a shorter time than the other
way round.
Some industrial customers want
the assurance that a salesperson
understands their needs as far as
the technical aspects of their plant
or equipment in rela-tionship to
the lubrication solution on offer is
concerned.
While it is of great advantage to
have a technical background when
handling lubes sales, it would be
prudent on your part to admit to
your client your limited technical
knowledge if you don’t have any
technical academic background. It
is very expensive to make a mistake
and have a customer use the wrong
lubricating oil in a 20 million shil-
ling plant.
Don’t stop there. Assure the client
that you will get all the details to him
as soon as possible and then start
chasing your company’s technical
guy! Sales and marketing is more
about relationships rather than
actual sales. Sales bring in revenue-

SPANCOAs I said earlier, sales is the front end of any business and the sales employee needs to take a few initiative steps to make the sales process less cumbersome and less frustrat-ing.Market leaders in the field of marketing came up with a systematic strategy for closing a sale which is called SPANCO (Suspect, Prospect, Approach, Negotiate, Closure, Order)
SuspectInvestigate about the particular account or prospect. Know the contact persons, the company authority and the financial muscle of the firm if you can. Understand their need and evaluate your ability to meet that need. Probe well enough to know if it’s a hot or cold account.
ProspectMove forward to handle the account as ‘warm’ based on what you think is their need. Start building a relationship.
ApproachGet in touch with the contact person seek-ing to know the competitors in the account and suggest what better services you can off er. As much as it possible, be in contact with the decision makers.
NegotiateBefore you touch this very crucial part of the sales process, make sure you are well versed with your product cost build-up to ensure healthy margins. It is a balancing act of ensuring that you maximise on the profit without losing the business to your competition. Many companies will furnish the salesman with all the details from product cost of production or purchase, logistical costs, taxes, overhead costs per unit and desired margins, etc otherwise called the price build-up. Other companies will simply give a price and the maximum discount the salesperson is permitted to allow. A very important thing at this point will be to give your customer the confidence that you are the salesperson and that you are in control of the sales process.
ClosureOnce the negotiation is done and price agreed, the salesperson needs to close the deal making very clear issues like terms of payment and delivery terms in writing.
OrderA signed and stamped purchase order reflecting all the above should be ob-tained. This will ensure a binding contract agreed by both parties is in place. .
