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 m
aximum
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.
