Maintenance Guidelines
Maintenance Guidelines - Overview
Cummins Inc. recommends that the engine be maintained according to the Maintenance Schedule in this section. If the engine is operating in ambient temperatures below -18°C [0°F] or above 38°C [100°F], perform maintenance at shorter intervals. Shorter maintenance intervals are also required if the engine is operated in a dusty environment or if frequent stops are made. Contact your authorized dealer and local Cummins Authorized Repair Location for recommended maintenance intervals. Some of these maintenance procedures require special tools or must be completed by qualified personnel. Contact your local Cummins Authorized Repair Location for detailed information. If your engine is equipped with a component or accessory not manufactured by Cummins Inc., refer to the component manufacturer's maintenance recommendations. Use the chart provided in this section as a convenient way to record maintenance performed.

1. Limit oil change interval to 250-hour maximum for oil grades if 40% of the operating time is in ambient temperatures above 38°C (100°F) to prevent engine damage to oil degradation resulting from high oil temperature. 2. We don't recommended the use of CF or CG grade oils. If CF or CG oil must be used, make the oil drain intervals half of the API CH-4 values. 3. Engine oil drain intervals need to be reduced by 50% when fuel sulfur content exceeds 0.5% (5,000 ppm) 4. Oil filters must CES 10065 (Cummins Engineering Spec.) specifications. Fleetguard LF9009 meets and exceeds these requirements. 5. Valvoline Premium Blue meet CES 20076 standards. - recommended in North America.
