Adjustment of the Oil Change Interval
Note: Your Caterpillar dealer has additional information on these programs.Program A
Verification for an Oil Change Interval of 500 HoursThis program consists of three oil change intervals of 500 hours. Oil sampling and analysis is done at 250 hours and 500 hours for each of the three intervals for a total of six oil samples. The analysis includes oil viscosity and infrared (IR) analysis of the oil. If all of the results are satisfactory, the 500 hour oil change interval is acceptable for the machine in that application. Repeat Program A if you change the application of the machine.If a sample does not pass the oil analysis, take one of these actions:
Shorten the oil change interval to 250 hours.
Proceed to Program B.
Change to a preferred oil type in Table 1 or Table 2.Program B
Optimizing Oil Change IntervalsBegin with a 250 hour oil change interval. The oil change intervals are adjusted by increments. Each interval is adjusted an additional 50 hours. Periodic oil sampling and analysis is done during each interval. The analysis includes oil viscosity and infrared (IR) analysis of the oil. Repeat Program B if you change the application of the machine.If an oil sample does not pass the analysis, shorten the oil change interval, or change to a preferred multigrade oil type in the listing above.References

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
Open the engine hood.
The drain plug is located on the left side of the engine oil pan toward the rear of the machine. Open the oil drain valve and allow the oil to drain into a suitable container. Close the drain valve.
