2013 JEEP GRAND CHEROKEE oil additives

When you do switch fuel types it is recommended that:
•you do not add less than 5 gallons (19 Liters) when
refueling
•you drive the vehicle immediately after refueling for at
least 5 miles (8 km)
Observing these precautions will avoid possible hard
starting and/or significant deterioration in driveability
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).•Some additives used in regular gasoline are not fully
compatible with E-85 and may form deposits in your
engine. To eliminate driveability issues that may be
caused by these deposits, a supplemental gasoline addi-
tive, such as MOPAR® Injector Cleanup or Techron may
be used.
Selection Of Engine Oil For Flexible Fuel Vehicles
(E-85) And Gasoline Vehicles
FFV vehicles operated on E-85 require specially formulated
engine oils. These special requirements are included in
MOPAR® engine oils, and in equivalent oils meeting
Chrysler Specification MS-6395. The manufacturer only
recommends engine oils that are API Certified and meet
the requirements of Material Standard MS-6395. MS-6395
contains additional requirements, developed during exten-
sive fleet testing, to provide additional protection to
Chrysler Group LLC engines. Use MOPAR® or an equiva-
lent oil meeting the specification MS-6395.
548 STARTING AND OPERATING

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.
Engine Oil Viscosity – 5.7L 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 “Engine Compart-
ment” in “Maintaining Your Vehicle” for further informa-
tion.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 Fuel Saver Technology. Refer to “Fuel Saver Technol-
ogy – If Equipped” in “Starting and Operating” for further
information.
Lubricants that do not have both, the engine oil certification
mark and the correct SAE viscosity grade number 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.
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.
