Intervals for normal duty - must be reduced for lower average speeds/duty cycles.

Default interval is the hours stated. Interval is whichever comes first – hours, miles or time.

Refer to Owners Manual for complete details on Maintenance Intervals.

* Assuming normal duty cycle/based on 45 mph average speed.

Spark plug interval and overhead adjustment must be reduced for slower speed applications.

Maintenance Cost

Cost of maintenance related to ignition and overhead valve

adjustments adds incremental maintenance cost for the ISL G

versus ISL9. This cost is typically more than offset by fuel cost

savings with natural gas.

Lubricating OilNatural gas engines require a specific oil that meets Cummins

specification CES 20074

Noise Natural gas engines are up to 10db quieter at idle

ISL G: The Right Applications

Medium Duty Market

– Refuse / Dump / Mixer

– Transit and School Bus

– Pickup and Delivery Truck

– Medium Duty Specialty Vehicles (street

sweeper, yard spotter, etc…)

Heavy Duty Market

– Up to 66,000 lbs GVW

– Less Than Truck Load (LTL) applications

– Regional / Bulk Haul applications

• Distance intervals will increase or decrease based on average speeds.

• The default interval is the hours shown. Perform maintenance at hours, distance, or months indicated, whichever comes first

• A service interval distance reduction exists in severe duty applications (>66,000 lbs)

• Refer to the Owners Manual for complete details on Maintenance Intervals

¹ If the engine is equipped with an optional coolant filter, the coolant filter will need to be replaced at the same intervals as the oil filter.

Regardless of whether the engine is or is not equipped with a coolant filter, SCA/DCA additive levels must be checked according to the

interval listed in the Owners Manual.

* Assuming truck is normal duty cycle @ 30 mph avg. speed.

* Use Natural Gas Engine Oil (CES20074)
