Fuel Requirements
If your vehicle is E-85 compatible, it will operate on
unleaded gasoline with any octane rating, or solely E-85
fuel, or any mixture of these fuels.
For best results, avoid fueling patterns alternating
between 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
starting and/or driveability problems during warm up. 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.
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

Lubricants that do not have both, the engine oil certifi-
cation mark and the correct SAE viscosity grade number
should not be used.
Synthetic Engine Oils
You may use synthetic engine oils provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes
are followed.
Synthetic engine oils which do not have both the engine
oil certification mark and the correct SAE viscosity grade
number should not be used.
Materials Added To Engine Oil
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental addi-
tives.
Disposing Of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your authorized dealer, service
station or governmental agency for advice on how and
where used oil and oil filters can be safely discarded in
your area.
Engine Oil Filter
The engine oil filter should be replaced with a new filter
at every engine oil change.
Engine Oil Filter Selection
This manufacturer’s engines have a full-flow type oil
filter. Use a filter of this type for replacement. The quality
of replacement filters varies considerably. Only high
