TECHNICAL SPECIFICATIONS 255
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,
developed 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 (lags and/or
hesitations) until the engine is fully warmed up.
These issues may be improved with the use of
seasonally 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.
Maintenance
CAUTION!
Replacing fuel system components with
non-ethanol compatible components can
damage your vehicle.
CAUTION!
Do not use ethanol mixture greater than 85%
in your vehicle. It will cause difficulty in cold
starting and may affect drivability.
