oil viscosity JEEP LIBERTY 2006 KJ / 1.G Owners Manual

•Check 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.
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 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.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 71

IfANY of these apply to you, then change your engine oil
at every interval shown in schedule “B” of the “Mainte-
nance Schedules” section of this manual.
If none of these apply to you, then change your engine oil
at every interval shown on schedule “A” of the “Main-
tenance Schedules” section of this manual
NOTE: Under no circumstances should oil change in-
tervals exceed 6,000 miles (10 000 km) or 6 months
whichever comes first.
Engine Oil Selection (Gasoline Engines)
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 recommends
API Certified engine oils.
Engine Oil Viscosity (3.7L Engines)
SAE 5W-30 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy. Your engine oil filler
cap also shows the recommended engine oil viscosity for
your vehicle.

Lubricants which do not have both, the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used.
Engine Oil Selection (Diesel Engines)
For best performance and maximum protection for all
engines under all types of operating conditions, the
manufacturer recommends using synthetic engine oils
that meet API categories SM and CF (SM/CF), and meet
the requirements of DaimlerChrysler Material Standard
MS-10725.
Engine Oil Viscosity (2.8L Diesel Engines)
Use SAE 0W-40 Synthetic Engine Oil that meets API
categories SM and CF (SM/CF) or better and the re-
quirements of DaimlerChrysler Material Standard MS-
10725. If you cannot find SAE 0W-40, then SAE 5W-40
Synthetic Engine Oil is acceptable. Any engine oil that
does not meet the manufacturer’s requirements should
not be used. Your engine oil filler cap also shows the recommended
engine oil viscosity for your vehicle.
Synthetic Engine Oils — Gasoline Engines
There are a number of engine oils being promoted as
either synthetic or semi-synthetic. If you chose to use
such a product, use only those oils that are certified by
the American Petroleum Institute (API) to display the
symbol on the front of the container or the proper ACEA
category and show the recommended SAE viscosity
grade. Follow the service schedule that describes your
driving type.
Materials Added To Engine Oils
The manufacturer
strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
engine oil. Engine oil is an engineered product and it’s
performance may be impaired by supplemental addi-
tives.
