OXYGENATED FUELS
Some conventional gasolines are 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 using an oxygenated fuel, make sure it is unleaded and
meets the minimum octane rating requirements. 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:
Ethanol (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.”
Do not use E85 fuel.
MTBE (methyl tertiary butyl ether) 15% by volume. You
may use gasoline containing up to 15% MTBE by volume.
Methanol (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 the product or your fuel system.
If you notice any undesirable operating symptoms, try another
service station or switch to another brand of gasoline.
NOTE: Fuel system damage or performance problems
resulting from the use of an oxygenated fuel containing more
than the percentages of oxygenates stated previously are
not covered under warranty.
