TECHNICAL AND CONSUMER INFORMATION
Some conventional gasolines are
being blended with alcohol or an
ether compound. These gasolines are
collectively referred to as oxygenated
fuels. To meet clean air standards,
some areas of the United States and
Canada use oxygenated fuels to help
reduce emissions.
If you use an oxygenated fuel, be
sure it is unleaded and meets the
minimum octane rating requirement.
Before using an oxygenated fuel, try
to confirm the fuel’s contents. Some
states/provinces require this
information to be posted on the pump.
The following are the EPA-approved
percentages of oxygenates:
ethyl or grain alcohol;
10% by volume.
You may use gasoline containing up
to 10% ethanol by volume. Gasoline
containing ethanol may be marketed
under the name ‘‘Gasohol’’.
Methyl Tertiary Butyl Ether;
15% by volume.
You may use gasoline containing up
to 15% MTBE by volume.
methyl or wood
alcohol; 5% by volume.
You may use gasoline containing up
to 5% methanol by volume, as long
as it also contains cosolvents and
corrosion inhibitors to protect the
fuel system. Gasoline containing
more than 5% methanol by volume
may cause starting and/or
performance problems. It may also
damage metal, rubber, and plastic
parts of your fuel system.
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
mentioned above are not covered
under warranty.
