Topping Up the Engine Oil
If checking the engine oil just after stopping
the engine, wait 15 minutes for the oil to
drain back into the oil pan before checking
the fluid level.
This procedure should be followed when oil
level is low and more oil needs to be
added.
1. Top up with oil, if necessary, via the
filler opening. Use the correct
grade in the correct quantity.
2. After topping up, wait one minute
and check the oil level again.
3. Reinstall the oil fill cap and twist to
lock it in place.
Engine Oil Filter
Always use quality engine lubricating oils in
conjunction with the appropriate oil drain
and filter change intervals. Refer to the
“Preventative Maintenance Schedule” for
the recommended oil and filter change
service interval.
CAUTION
Use of non-genuine PACCAR oil filters
can cause severe engine damage.
Oil Filter Removal Preparation
CAUTION
The oil change process must be com-
pleted, the engine restarted, and idled
for five minutes before beginning the
fuel filter change process. Failure to
comply could result in a non-warrantable
engine failure.
