FLEXIBLE FUEL (3.6L ENGINE ONLY)

E-85 General Information

The information in this section is unique for Flexible Fuel vehicles only. These vehicles can be identified by a unique fuel filler door label that states Ethanol (E-85) or Unleaded Gasoline Only and/or a yellow fuel cap. Please refer to the other sections of this manual for information on features that are common between Flexible Fuel and Non-Flexible Fuel powered vehicles.

is a mixture of approximately 85% ethanol and 15% unleaded gasoline.

If your vehicle is E-85 compatible, it will operate on unleaded gasoline with any octane rating greater than 87 (R+M)/2, or solely E-85 fuel, or any mixture of these fuels.

For best results, avoid fueling patterns alternating be- tween E-85 and unleaded gasoline.

When switching fuel types:

Add 5 gallons (19 liters) or more when refueling.

Drive the vehicle immediately after refueling for at least 5 miles (8 km).

Observing these precautions will avoid possible hard start- ing and/or driveability problems during warm up.

(Continued)

NOTE:

Use seasonally adjusted E-85 fuel (ASTM D5798). With non-seasonally adjusted E-85 fuel, hard starting and rough idle following start up may be experienced 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.

Starting

The characteristics of E-85 fuel make it unsuitable 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 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).

(E-85) And Gasoline Vehicles

Because E-85 fuel contains less energy per gallon/liter than 9

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 FCA US Material Standard MS-6395. It is recommended that engine oils that are API Certified and meet the requirements 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.

gasoline, an increase in fuel consumption will be experi- enced. The miles per gallon (mpg)/kilometers per liter and the driving range will decrease by approximately 30%, compared to gasoline operation.

All fuel and engine components in your Flexible Fuel Vehicle (FFV) are designed to be compatible with ethanol. Ethanol compatible service components are required.
