Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience
these symptoms, try another brand of gasoline before
considering service for the vehicle.
6.4L ENGINE
Do not use E-85 flex fuel or ethanol blends greater than
15% in this engine.
Your vehicle is designed to operate using high-quality
unleaded gasoline having a Research Octane Number
(RON) of 91.
METHANOL
(Methyl) is used in a variety of concentrations when
blended with unleaded gasoline. You may find fuels
containing 3% or more methanol along with other alco-
hols called cosolvents. Problems that result from using
methanol/gasoline are not the responsibility of the
manufacturer. While methly tert-butly ether (MTBE) is
an oxygenate made from methanol, it does not have the
negative effects of methanol.
WARNING!
Do not use gasolines containing methanol. Use of
these blends may result in starting and drivability
problems and may damage critical fuel system
components.
ETHANOL
The manufacturer recommends that your vehicle be
operated on fuel containing no more than 15% ethanol.
Purchasing your fuel from a reputable supplier may
reduce the risk of exceeding this 15% limit and/or of
receiving fuel with abnormal properties. It should also
be noted that an increase in fuel consumption should
be expected when using ethanol-blended fuels, due to
the lower energy content of ethanol. Problems that
result from using methanol/gasoline or E-85 ethanol
blends are not the responsibility of the manufacturer.
CAUTION!
Use of fuel with ethanol content higher than 15% may
result in engine malfunction, starting and operating
difficulties, and materials degradation. These adverse
effects could result in permanent damage to your
vehicle.
REFORMULATED GASOLINE
Many areas of the country require the use of cleaner
burning gasoline referred to as “reformulated gasoline”.
Reformulated gasoline contains oxygenates and are
specifically blended to reduce vehicle emissions and
improve air quality.
The use of reformulated gasoline is recommended.
Properly blended reformulated gasoline will provide
improved performance and durability of engine and fuel
system components.
MATERIALS ADDED TO FUEL
Besides using unleaded gasoline with the proper
octane rating, gasolines that contain detergents, corro-
sion and stability additives are recommended. Using
gasolines that have these additives will help improve
fuel economy, reduce emissions, and maintain vehicle
performance.
Indiscriminate use of fuel system cleaning agents
should be avoided. Many of these materials intended
for gum and varnish removal may contain active sol-
vents or similar ingredients. These can harm fuel sys-
tem gasket and diaphragm materials.
DO NOT USE E-85 IN NON-FLEX
FUEL VEHICLES
Non-Flex Fuel Vehicles (FFV) are compatible with gaso-
line containing up to 15% ethanol (E-15). Use of gaso-
line with higher ethanol content may void the New
Vehicle Limited Warranty.
If a Non-FFV vehicle is inadvertently fueled with
E-85 fuel, the engine will have some or all of these
symptoms:
•
Operate in a lean mode.
•
OBD II Malfunction Indicator Light on.
•
Poor engine performance.
•
Poor cold start and cold drivability.
•
Increased risk for fuel system component corrosion.
