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

Open the engine hood.
The crankcase drain valve is located on the right side of the oil pan beneath the machine. Open the crankcase drain valve and allow the oil to drain into a suitable container. Close the drain valve.

Use a strap type wrench to remove filter element (1) from the left side of the machine. Inspect the oil filter.ReferenceRefer to Operation and Maintenance Manual, "Oil Filter - Inspect".
Clean the filter housing base. Make sure that all of the used filter gasket is completely removed.

Apply a thin coat of clean engine oil to the sealing surface of the new filter element.
Install the new filter element by hand. After the gasket contacts the filter base, tighten the filter by an additional 3/4 turn.

Some machines are equipped with an additional bypass oil filter (2) on the right side of the machine near the fuel filter. Use Steps 3 through 6 to replace the bypass oil filter.
Remove filler cap (3) . Fill the crankcase with new oil.ReferenceRefer to Operation and Maintenance Manual, "Lubricant Viscosities and Refill Capacities" for the correct type of oil and for the correct amount of oil.
Clean the filler cap and install the filler cap.
Start the engine and allow the oil to warm. Check for leaks.
Check the oil level on dipstick (4) .ReferenceRefer to Operation and Maintenance Manual, "Engine Oil Level - Check" for the correct procedure.
Close the engine hood and stop the engine.
