2004 DODGE DURANGO oil viscosity

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 miles (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 anticipated climate
conditions under which vehicle operations will occur.
The recommended viscosity and quality grades are
shown in Section 7.
NON-DETERGENT OR STRAIGHT MINERAL OILS
MUST NEVER BE USED.A new engine may consume some oil during its first few
thousand miles of operation. This is a normal part of the
break-in and is not an indication of difficulty.
SAFETY TIPS
Exhaust System
WARNING!
Exhaust gases contain carbon monoxide, an ex-
tremely toxic gas that by itself is colorless and
odorless. To avoid inhaling these gases, the follow-
ing precautions should be observed:
²Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in
or out of the area.

periodically. Make sure that these units are always clean.
This will tend to reduce to a minimum the amount of
abrasive material that may enter the engine.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacture only
recommends engine oils that are API certified and meet
the requirements of DaimlerChrysler Material Standard
MS-6395. Use Mopar or an equivalent oil meeting the
specification MS-6395.
Engine Oil Identification (API) Symbol
There is a symbol to aid you in selecting the proper
engine oil.This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacture only recommends
API Certified engine oils that
meet the requirements of
DaimlerChrysler Material Stan-
dard MS-6395. Use Mopar or an
equivalent oil meeting the specifi-
cation MS-6395.
Engine Oil Viscosity Chart
The proper SAE viscosity grade of engine oil should be
selected based on the following recommendation and be
within the operating temperature shown in the recom-
mended SAE viscosity chart.
²SAE 5W-30 is the preferred oil for Dodge Trucks with
3.7L/4.7L/5.7L engines. Synthetic engine oils may be

used provided that the oil quality requirements de-
scribed above are met and the recommended mainte-
nance intervals for oil and filter changes are followed.
²Lubricants which do not have both the engine oil
certification mark or current service symbol and the
correct viscosity grade number should not be used.
Synthetic Engine Oils
There are a number of engine oils being promoted as
either synthetic or semi-synthetic. If you chose to use
such a product, useonlythose oils that meet the Ameri-
can Petroleum Institute (API) and SAE viscosity stan-
dard. Follow the service schedule that describes your
driving type.
Materials Added to Engine Oils
The manufacture strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and
it's performance may be impaired by supplemental ad-
ditives.
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 dealer, service station, or
