2.0L E
NGINE
This engine is designed to meet all emission
regulations, and provide satisfactory fuel economy
and performance when using high-quality
unleaded gasoline with a recommended
RON of 95.
M

ETHANOL

(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 alcohols called cosolvents. Problems
that result from using methanol/gasoline are not
the responsibility of the manufacturer. While
Methyl Tert-Butyl 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.
E
THANOL
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.

EFORMULATED
ASOLINE
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.

UEL
Besides using unleaded gasoline with the proper
octane rating, gasolines that contain detergents,
corrosion 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 solvents or similar ingredients. These can
harm fuel system gasket and diaphragm materials.
