Selection of Oil Change Interval
Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact the skin.
Caterpillar oil filters are recommended for oil changes. Recommended multigrade oil types are listed in Table 1. Do not use single grade oils. Any oil that is used in a Caterpillar engine must meet the ECF-1-a standard. Abnormally harsh operating cycles or harsh environments can shorten the service life of the engine oil. Arctic temperatures, corrosive environments, or extremely dusty conditions may require a reduction in engine oil change intervals from the recommendations in Table 1. Poor maintenance of air filters or of fuel filters requires reduced oil change intervals. See your Caterpillar dealer for more information if this product will experience abnormally harsh operating cycles or harsh environments. Refer to this Operation and Maintenance Manual, "Refill Capacities and Recommendations" for further information about oils that may be used in Caterpillar engines.

(1) The standard oil change interval in this engine is 250 hours, if the operating conditions and recommended oil types that are listed in this table are met. If the type of oil, the quality of the oil and the operating conditions meet certain standards, the oil change intervals may be increased to 500 hours. Refer to Special Publication, PEDP7035, "Optimizing Oil Change Intervals" in order to determine whether the oil change interval can be extended beyond 250 hours.
(2) Normal conditions include these factors: Fuel sulfur below 0.3%, altitude below 1830 m (6000 ft) and good air filter and fuel filter maintenance. Normal conditions do not include high load factor, harsh operating cycles, or harsh environments.
(3) High load factors can shorten the service life of your engine oil. Continuous heavy load cycles and very little idle time result in increased fuel consumption and oil contamination. These factors deplete the oil additives more rapidly. If the average fuel consumption of your engine exceed 43 L (11 US gal) per hour, follow the “High Load Factor” recommendations in Table 1. To determine average fuel consumption for your engine, measure average fuel consumption for a period of 50 to 100 hours. If the application of the engine is changed, the average fuel consumption may change.
(4) For sulfur content above 0.5%, refer to, "Total Base Number (TBN) and Fuel Sulfur Levels for Direct Injection (DI) Diesel Engines" in Special Publication, SEBU6251, "Caterpillar Commercial Diesel Engine Fluids Recommendations".
(5) In order to verify an oil change interval of 500 hours, refer to "Program A" below.
(6) Use "Program A" below to determine an appropriate interval.Adjustment of the Oil Change Interval
