A 500 hour engine oil change interval is available, provided that the operating conditions and recommended multigrade oil types are met. When these requirements are not met, shorten the oil change interval to 250 hours, or use an S·O·S Services oil sampling and analysis program to determine an acceptable oil change interval. If you select an interval for oil and filter change that is too long, you may damage the engine. |
- Open the engine compartment cover on the left side of the machine.
- Obtain the regularly scheduled oil sample, if necessary.
