oil viscosity JEEP WRANGLER 2013 JK / 3.G Owners Manual

ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 500 miles (800 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.
Wide-open throttle acceleration in low gear can be detri-
mental and should be avoided. Trailer tow is not recom-
mended during break in period.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. For
the recommended viscosity and quality grades, refer to
“Maintenance Procedures” in “Maintaining Your Ve-
hicle”. NON-DETERGENT OR STRAIGHT MINERAL
OILS MUST NEVER BE USED.
A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered a normal part of the break-in and not inter-
preted as an indication of difficulty.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 99

Engine Oil Viscosity – 3.6L Engine
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 “Engine Com-
partment” illustration in this section.
NOTE:SAE 5W-30 engine oil approved to Fiat 9.55535-S1
or Fiat 9.55535-S3 may be used when SAE 5W-20 engine
oil meeting MS- 6395 is not available.
Synthetic Engine Oils
You may use synthetic engine oils provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes
are followed.
Materials Added To Engine Oil
The manufacturer 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 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.
