2009 JEEP GRAND CHEROKEE oil viscosity

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 recommended viscosity and quality grades are
shown under “Engine Oil”, under “Maintenance Proce-
dures” in section 7 of this manual. NON-DETERGENT
OR STRAIGHT MINERAL OILS MUST NEVER BE
USED.
68 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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

Engine Oil Viscosity (3.7L/4.7L/5.7L Engines)
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.
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 Viscosity (3.0L Diesel Engine)
CAUTION!
Your vehicle is equipped with an advanced technol-
ogy Diesel Engine and an emission device designed
to limit Diesel Particulate Emissions from being
released into the atmosphere. The durability of your
engine and life expectancy of this diesel particulate
filter emission device is highly dependent on the use
of the correct engine oil.
SAE 5W-30 Synthetic Low Ash engine oil is recom-
mended for all operating temperatures. This engine oil
improves low temperature starting and vehicle fuel
economy.
416 MAINTAINING YOUR VEHICLE

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.
Synthetic Engine Oils
You may use synthetic engine oils if the recommended oil
quality requirements are met, and the recommended
maintenance intervals for oil and filter changes are
followed.
Materials Added to Engine Oils
The manufacturerstrongly recommendsagainst the ad-
dition 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 local authorized dealer, ser-
vice 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 oil change.
Engine Oil Filter Selection
The manufacturer’s engines have a full-flow type dispos-
able oil filter. Use a filter of this type for replacement. The
quality of replacement filters varies considerably. Only
high-quality filters should be used to assure most effi-
cient service. MOPARengine oil filters are high-quality
oil filters and are recommended.
Engine Air Cleaner Filter
Refer to the “Maintenance Schedule” in Section 8 for the
proper maintenance interval.
