General Information
CAUTION
Extending the oil and lter change
interval beyond the recommenda
-
tions will decrease the engine life
due to factors such as corrosion,
deposits, and wear. Engine oil lters
capture dirt and remove deposits
from the oil to prolong the life of in
-
ternal moving components. Follow
the oil and lter change intervals
as recommended in this section of
the manual. Failure to comply may
result in equipment or property dam

age.
A major factor in maintaining engine
performance and durability is the
proper use of quality engine lubricating
oils used in conjunction with the
appropriate oil drain and lter change
intervals. Attempting
to extend the oil
and lter change interval beyond the
manufacturers recommendations may
decrease engine life.
NOTE
It is
the operator’s responsibility to
abide by these recommendations
to ensure that the engine warranty
does not get affected.
PACCAR
recommends the use of
high-quality SAE 10W30 API CJ-4
heavy-duty engine oil.
The primary
PACCAR
recommendation is for the use of
10W30 multigrade lubricating oil
for normal operation at ambient
temperatures above 5°F (-15°C).
For ambient temperatures below
5°F (-15°C) SAE 5W30 may be
used, provided it meets API CJ-4
oil specications and biodiesel or
biodiesel blended fuel is not used as
