2014 JEEP GRAND CHEROKEE fuel additives

•Change the engine oil and oil filter.
• Disconnect and reconnect the battery to reset the
engine controller memory.
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (MMT)
is a manganese-containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emissions system performance in some vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. MMT is prohibited in Federal
and California reformulated gasoline.
Materials Added To Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and they would result in additional cost.
Therefore, you should not have to add anything to the
fuel.

STARTING AND OPERATING 501

Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine perfor-
mance and damage the emissions control system.
• An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate ser-
vice. Contact your authorized dealer for service
assistance.
(Continued)
CAUTION! (Continued)
•The use of fuel additives, which are now being
sold as octane enhancers, is not recommended.
Most of these products contain high concentrations
of methanol. Fuel system damage or vehicle perfor-
mance problems resulting from the use of such
fuels or additives is not the responsibility of the
manufacturer.
NOTE: Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.
502 STARTING AND OPERATING

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 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
additive, 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 formu-
lated 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 ex-
tensive fleet testing, to provide additional protection to
Chrysler Group LLC engines. Use MOPAR® or an
equivalent oil meeting the specification MS-6395.5
