oil viscosity JEEP COMMANDER 2009 1.G Owners Manual

For the outboard seating positions, route the tether over
the head rests, and attach the hook to the tether anchor
located on the back of the seat.
WARNING!
An incorrectly anchored tether strap could lead to
increased head motion and possible injury to the
child. Use only the anchor positions directly behind
the child seat to secure a child restraint top tether
strap.
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 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 detri-
mental 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 recom-
mended viscosity and quality grades are shown under
“Engine Oil”, under “Maintenance Procedures” in section 7
of this manual. NON-DETERGENT OR STRAIGHT MIN-
ERAL OILS MUST NEVER BE USED.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 73
2

For best results, a refueling pattern that avoids alternat-
ing between E-85 and unleaded gasoline is recom-
mended.
When you do switch fuel types it is recommended that:
•you do not add less than 5 gal (19 L) when refueling
•you drive the vehicle immediately after refueling for at
least 5 mi (8 km)
Observing these precautions will avoid possible hard
starting and/or significant deterioration in drivability
during warm up.
NOTE:Use seasonally adjusted E-85 fuel (ASTM
D5798). With non-seasonally adjusted E-85 fuel, you may
experience hard starting and rough idle following start
up even if the above recommendations are followed,
especially when the ambient temperature is below 32°F
(0°C).
Selection Of Engine Oil For Flexible Fuel Vehicles
(E-85) and Gasoline Vehicles
Whether operating the vehicle on an E-85 ethanol fuel or
unleaded gasoline, the engine oil requirements are the
same. Refer to “Maintenance Procedures” in Section 7 of
this manual for the proper quality and viscosity engine
oil.
Starting
The characteristics of E-85 fuel make it unsuitable for use
when ambient temperatures fall below 0°F (-18°C). In the
range of 0° to 32°F (-18° to 0°C), you may experience an
increase in the time it takes for your engine to start, and
a deterioration in drivability (sags and/or hesitations)
until the engine is fully warmed up.
Cruising Range
Because E-85 fuel contains less energy per gallon/liter
than gasoline, you will experience an increase in fuel
374 STARTING AND OPERATING

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 Chrysler 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 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 vehicle. For information on
engine oil filler cap location, refer to “Engine Compart-
ment” in this section.
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 Multiple Displacement System (MDS).
Refer to “Multi-Displacement System” in Section 5 for
more details.
Lubricants, which do not have both the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber, should not be used.
