Ethanol Fuel (E-85)

E-85 is a mixture of approximately 85% ethanol
and 15% unleaded gasoline.
WARNING!
Ethanol vapors are extremely flammable and
could cause serious personal injury. Never
have any smoking materials lit or products
that can cause spark in or near the vehicle
when removing the fuel filler tube cap (gas
cap) or filling the tank. Do not use E-85 as a
cleaning agent and never use it near an open
flame.

Fuel Requirements

Your vehicle will operate on both unleaded
gasoline with a minimum Research Octane
Number (RON) of 91, or E-85 fuel, or any
mixture of these two. For best results, a refuel-
ing pattern that alternates between E-85 and
unleaded gasoline should be avoided.
When you do switch fuel types it is recom-
mended that:
• You do not add less than 5 gallons (19 liters)
when refueling.
• You operate the vehicle immediately after
refueling for a period of at least five minutes.
Observing these precautions will avoid possible
hard starting and/or significant deterioration in
driveability during warm up.
NOTE:
• When the ambient temperature is above 90°F
(32°C), you may experience hard starting and
rough idle following start up even if the above
recommendations are followed.
• Some additives used in regular gasoline are
not fully compatible with E-85 and may form
deposits in your engine. To eliminate drive-
ability 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
formulated engine oils. These special require-
ments are included in Mopar engine oils, and in
equivalent oils meeting FCA US Material Stan-
dard MS-6395. It is recommended that engine
oils that are API Certified and meet the require-
ments of Material Standard MS-6395 be used.
MS-6395 contains additional requirements, de-
veloped during extensive fleet testing, to provide
additional protection to FCA US LLC engines.

Starting

The characteristics of E-85 fuel make it unsuit-
able for use when ambient temperatures fall
below 0°F (-18°C). In the range of 0°F (-18°C) to
32°F (0°C), an increase in the time it takes for
your engine to start may be experienced, and a
deterioration in driveability (sags and/or hesita-
tions) until the engine is fully warmed up. These
issues may be improved with the use of season-
ally adjusted E-85 fuel.
NOTE:
Use of the engine block heater (if equipped)
may improve engine start time when using E-85
fuel when the ambient temperature is less than
32°F (0°C).

Cruising Range

Because E-85 fuel contains less energy per
gallon/liter than gasoline, an increase in fuel
consumption will be experienced. The miles per
gallon (mpg)/kilometers per liter and the driving
range will decrease by approximately 30%,
compared to gasoline operation.

Replacement Parts

All fuel and engine components in your Flexible
Fuel Vehicle (FFV) are designed to be compat-
ible with ethanol. Ethanol compatible service
components are required.
CAUTION!
Replacing fuel system components with non-
ethanol compatible components can damage
your vehicle.
