turer recommends the use of gasoline that
meets the WWFC specifications if they are
available.
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
may
help
improve
fuel
economy, reduce emissions, and maintain ve-
hicle performance.
Poor quality gasoline can cause problems such
as hard starting, stalling and stumble. If you
experience these problems, try another brand
of gasoline before considering service for the
vehicle.
Methanol
(Methyl or Wood Alcohol) 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 or E-85 Ethanol blends are
not the responsibility of the manufacturer. While
MTBE is an oxygenate made from Methanol, it
does not have the negative effects of Methanol.
CAUTION!
Do not use gasolines containing Methanol or
E-85 Ethanol. Use of these blends may result
in starting and driveability problems and may
damage critical fuel system components.
Ethanol
The manufacturer recommends that your ve-
hicle be operated on fuel containing no more
than 10% Ethanol. Purchasing your fuel from a
reputable supplier may reduce the risk of ex-
ceeding this 10% 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. While MTBE
is an oxygenate made from Methanol, it does
not have the negative effects of Methanol.
CAUTION!
Use of fuel with Ethanol content higher than
10% may result in engine malfunction, starting
and operating difficulties and materials degra-
dation. These adverse effects could result in
permanent damage to your vehicle.
Clean Air Gasoline
Many gasolines are now being blended that
contribute to cleaner air, especially in those
areas where air pollution levels are high. These
new blends provide a cleaner burning fuel and
some are referred to as “reformulated gaso-
line.”
The manufacturer supports these efforts toward
cleaner air. You can help by using these blends
as they become available.
MMT in Gasoline
MMT is a manganese containing metallic addi-
tive that is blended into some gasoline to
increase octane. Gasoline blended with MMT
provides no performance advantage beyond
gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces
spark plug life and reduces emission system
