Oxygenated Fuels

Some gasolines are being blended
with alcohol or an ether compound.
These gasolines, or oxygenated fuels
are used to meet clean air standards
in the United States and Canada to
help reduce emissions.
If you use an oxygenated fuel, be
sure it is unleaded and meets the
minimum octane rating requirement.
Try to confirm the fuel's contents.
Some states/provinces require this
information to be posted on the
pump.

Technical Information
The following are the U.S. EPA and
Canadian CGSB approved
percentages of oxygenates:
ETHANOL (ethyl or grain alcohol)
You may use gasoline containing up
to 10 percent ethanol by volume.
Gasoline containing ethanol may be
marketed under the name ''Gasohol.''
MTBE (Methyl Tertiary Butyl
Ether)
You may use gasoline containing up
to 15 percent MTBE by volume.
METHANOL (methyl or wood
alcohol)
Your vehicle was not designed to use
fuel that contains methanol.
Methanol can corrode metal parts in
the fuel system, and also damage
plastic and rubber components. This
damage would not be covered by
your warranties.
If you notice any undesirable
operating symptoms, try another
service station or switch to another
brand of gasoline.
Fuel system damage or performance
problems resulting from the use of
an oxygenated fuel containing more
than the percentages of oxygenates
given above are not covered under
warranty.
