2007 JEEP LIBERTY 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.
Wide open throttle acceleration in low gear can be
detrimental and should be avoided.
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 of this manual. 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 as a normal part of the break-in and not
interpreted as an indication of difficulty.
SAFETY TIPS
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO)
follow the safety tips below.
•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a

Engine Oil Selection
For best performance and maximum protection for all
engines under all types of operating conditions, the
manufacturer recommends engine oils that are API Cer-
tified 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 0recommends
API Certified engine oils.
Engine Oil Viscosity
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low tempera-
ture starting and vehicle fuel economy. Your engine oil
filler cap also shows the recommended engine oil
viscosity for your vehicle.
For information on engine oil filler cap location, see the
Engine Compartment illustration in this section.
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 provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes
are followed.
