62 Oil System Oil Change Intervals The length of time an engine is operated before an oil change depends on which quality oil is used, the type of fuel used, engine oil consumption, vehicle application, level of dust in the air, etc. The change intervals given in this manual are maximum intervals. If the vehicle is operating in heavy-duty operation, dusty or off-road conditions, using high sulfur fuels, etc., adjust the intervals down for more frequent oil changes. Note: Oil filters should always be changed when changing oil. Oil Filters Always change oil filters when changing the oil. There are three filters on the engine, one of which is a bypass filter.
This should be changed at the same time as the regular full-flow filter(s). CAUTION Volvo branded oil filters are designed to provide the proper level of filtration and protection for Volvo engines. Filters that do not meet the same stringent requirements may cause unsatisfactory results. W2003930
