(1) The standard oil change interval for engines is 250 hours. The extended oil change interval in this machine is 500 hours if the following conditions are met. Acceptable operating conditions, recommended oil types, and an S O S oil sampling and analysis program are used. This extended interval is not permitted for other machines. Refer to the applicable Operation and Maintenance Manuals for the other machines.
(2) For sulfur content above 0.1%, refer to this topic in the Manual, SEBU6250, "Caterpillar Machine Fluid Recommendations".
(3) Use "Program B" below to determine an appropriate interval.Adjustment of the Oil Change Interval
Note: Your Cat dealer has additional information on these programs.Program B
Optimizing Oil Change IntervalsBegin with the standard oil change interval. The oil change intervals are adjusted by increments. Each interval is adjusted an additional 50 hours. Periodic oil sampling and analysis are 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.References

If the machine is equipped with a high speed oil change arrangement, use a nozzle assembly in order to drain the oil from the crankcase.
Illustration 3 g01051220
The access cover for the crankcase drain is located in the belly guard underneath the front of the machine. Remove the bolt in order to remove the access cover.
Illustration 4 g01047321
Open the crankcase drain valve. Allow the oil to drain into a suitable container. A drain hose may be attached to the crankcase drain valve in order to aid the draining of the oil.
When the oil has been drained from the crankcase, close the crankcase drain valve. Close the crankcase drain access cover.

Remove the crankcase oil filter elements (5) and discard the crankcase oil filter elements properly. Make sure that all of the old filter seals are removed from the filter base.
Apply a thin film of clean engine oil to the sealing surface of the new filter element.
Install the new oil filter elements by hand. Instructions for the installation of the filters are printed on the side of each Caterpillar spin-on filter. For non-Caterpillar filters, refer to the installation instructions that are provided by the supplier of the filter.
Install the crankcase drain plug.
Remove oil filler cap (7). Fill the crankcase with new oil. See Operation and Maintenance Manual, "Capacities (Refill)". Clean the oil filler cap and install the oil filler cap.
Always measure the oil level with
