•
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® Injec-
tor 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 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, devel-
oped during extensive fleet testing, to provide
additional protection to Chrysler Group LLC en-
gines. Use MOPAR® or an equivalent oil meeting
the specification MS-6395.
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), you may experience an increase in
the time it takes for your engine to start, and a
deterioration in driveability (sags and/or hesita-
tions) until the engine is fully warmed up.
NOTE:
Use of the engine block heater (if equipped)
is beneficial for E-85 startability 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, you will experience an
increase in fuel consumption. You can expect
your miles per gallon (mpg)/Kilometers per liter
and your driving range to decrease by about
30%, compared to gasoline operation.
Replacement Parts
Many components in your Flexible Fuel Vehicle
(FFV) are designed to be compatible with etha-
nol. Always be sure that your vehicle is serviced
with correct ethanol compatible parts.
CAUTION!
Replacing fuel system components with non-
ethanol compatible components can dam-
age your vehicle.
Maintenance
CAUTION!
Do not use ethanol mixture greater than 85%
in your vehicle. It will cause difficulty in cold
starting and may affect drivability.
