2008 DODGE RAM 3500 GAS oil viscosity

²The lap portion should be low on the hips and as snug
as possible.
²Check belt fit periodically. A child's squirming or
slouching can move the belt out of position.
If the shoulder belt contacts the face or neck, move the
child closer to the center of the vehicle. Never allow a
child to put the shoulder belt under an arm or behind
their back.
Transporting Pets
Airbags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
a collision. Pets should be restrained in the rear seat in
pet harnesses or pet carriers that are secured by seat belts.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine in
your new vehicle. Drive moderately during the first 300
miles (500 km). After the initial 60 mi (100 km), speeds up
to 50 or 55 mph (80 or 90 km/h) are desirable. While
cruising, brief full-throttle acceleration, within the limits
of local traffic laws, contributes to a good break-in.
Avoid wide-open throttle acceleration in low gear.
The engine oil installed in the engine at the factory is a
high-quality, energy-conserving type lubricant. Oil
changes should be consistent with the anticipated cli-
matic conditions under which vehicle operation will
occur. The recommended viscosity and quality grades are
discussed in Section 7 under Maintenance Procedures,
Engine Oil.
NON-DETERGENT OR STRAIGHT MINERAL OILS
MUST NEVER BE USED.
76 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Change Engine Oil
Follow the Maintenance Schedule for recommended en-
gine oil change intervals.
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 DaimlerChrysler 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.
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 the ªEngine Compartmentº illustration
in this section.
452 MAINTAINING YOUR VEHICLE

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 ªMulti-Displacement Systemº under ªStarting and
Operatingº in Section 5.
NOTE:For 2500/3500 trucks with a 5.7L engine oper-
ating under a gross combined weight rating of 14,000 lbs.
or greater, SAE 5W-30 engine oil is recommended for all
operating temperatures.
Lubricants, which do not have both the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber, should not be used.
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 addi-
tives.
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.
