Engine Oil

Checking Oil Level
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time to
check the engine oil level is about five minutes after a
fully warmed engine is shut off or before starting the
engine after it has sat overnight.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain
the oil level in the "SAFE" range. Adding one quart of oil
when the reading is at the bottom of the "SAFE" range
will result in an oil level at the top of the "SAFE" range
on these engines.
NOTE: Fill engine oil one quart at a time.
CAUTION!
• Overfilling or underfilling will cause oil aeration
or loss of oil pressure. This could damage your
engine.
• Operating the engine with the oil levels below the
safe zone, or operating with oil levels that exceed the
top of the safe zone may cause engine damage.
Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to "Maintenance Schedule" for further information.
NOTE: Under no circumstances should oil change in-
tervals exceed 6,000 miles (10 000 km) or six months,
whichever occurs first.
