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 approximately five
minutes after a fully warmed engine is shut off. Do not
check oil level before starting the engine after it has sat
overnight. Checking engine oil level when the engine is
cold will give you an incorrect reading.
Checking the oil while the vehicle is on level ground,
and approximately five minutes after a fully warmed
engine is shut off, will improve the accuracy of the oil
level readings. Maintain the oil level between the range
markings on the dipstick. The safe range is indicated by
a crosshatch zone. Adding 1 quart (0.9 Liters) of oil
when the reading is at the low end of the indicated
range will result in the oil level at the full end of the
indicator range.
CAUTION!
Do not overfill the engine with oil. Overfilling the
engine with oil will cause oil aeration, which can
lead to loss of oil pressure and an increase in oil
temperature. This loss of oil pressure and increased
oil temperature could damage your engine.
Change Engine Oil
The oil change indicator system will remind you that it
is time to take your vehicle in for scheduled mainte-
nance. Refer to the “Maintenance Schedule” for further
information.
NOTE:Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km), twelve
months or 350 hours of engine run time, whichever
comes first. The 350 hours of engine run or idle time is
generally only a concern for fleet customers.
Engine Oil Selection
For best performance and maximum protection for
turbocharged engines under all types of operating
conditions, the manufacturer recommends synthetic
engine oils that are API Certified and meet the require-
ments of FCA Material Standard MS-12991.
