Slots in the wheels will assist in properly orienting the
inner and outer wheels. Align these slots when assem-
bling the wheels for best access to the tire valve on the
inner wheel. The tires of both dual wheels must be
completely off the ground when tightening, to ensure
wheel centering and maximum wheel clamping.Dual wheel models require a special heavy-duty lug nut
tightening adapter (included with the vehicle) to cor-
rectly tighten the lug nuts. Also, when it is necessary to
remove and install dual rear wheels, use a proper vehicle
lifting device.
NOTE:When installing a spare tire as part of a dual rear
wheel end combination, the tire diameter of the two
individual tires must be compared. If there is a significant
difference, the larger tire should be installed in a front
location. The correct direction of rotation for dual tire
installations must also be observed.

CAUTION! (Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of
your vehicle and also allow extended maintenance
intervals. Do not use chemical flushes in these
components as the chemicals can damage your
engine, transmission, power steering or air condi-
tioning. Such damage is not covered by the New
Vehicle Limited Warranty. If a flush is needed
because of component malfunction, use only the
specified fluid for the flushing procedure.
Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, 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 up engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the
dipstick. Adding one quart of oil when the reading is at
the bottom of the SAFE zone will result in a reading at the
top of the safe zone on these engines.
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This 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 maintenance.
Refer to “Maintenance Schedule” for further information.

NOTE: Under no circumstances should oil change
intervals exceed 8,000 miles (13 000 km) or six months,
whichever occurs first.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only
recommends engine oils that are API Certified and meet
the requirements of Chrysler Material Standard MS-6395.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacturer only recommends
API Certified engine oils.
CAUTION!
Do not use chemical flushes in your engine oil as the
chemicals can damage your engine. Such damage is
not covered by the New Vehicle Limited Warranty.
Engine Oil Viscosity (SAE Grade)
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy. The engine oil filler
cap also shows the recommended engine oil viscosity for
your engine. For information on engine oil filler cap
location, refer to “Engine Compartment” in “Maintaining
Your Vehicle” for further information.
NOTE:Vehicles equipped with a 5.7L engine must use
SAE 5W-20 oil. Failure to do so may result in improper
operation of the Multi-Displacement System (MDS). Re-
fer to “Multi-Displacement System” in “Starting and
Operating” for further information.

Page 526 of 622

Lubricants which do not have both the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used.
NOTE:For 2500/3500 trucks with a 5.7L engine oper-
ating under a gross combined weight rating of 14,000 lbs
(6 350 kg) or greater, SAE 5W-30 engine oil is recom-
mended for all operating temperatures.
Synthetic Engine Oils
You may use synthetic engine oils if the recommended oil
quality requirements are met and the recommended
maintenance intervals for oil and filter changes are
followed.
Materials Added to Engine Oil
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental
additives.
Disposing of Used Engine Oil and Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your authorized dealer, service
station or governmental agency for advice on how and
where used oil and oil filters can be safely discarded in
your area.
Engine Oil Filter
The engine oil filter should be replaced with a new filter
at every engine oil change.
Engine Oil Filter Selection
The manufacturer’s engines have a full-flow type oil
filter. Use a filter of this type for replacement. The quality
of replacement filters varies considerably. Only high-
quality filters should be used to assure most efficient
service. MOPARengine oil filters are a high-quality oil
filter and are recommended.7
