oxyGEnatED FuEls
Some conventional gasolines are blended with alcohol or an ether
compound. These gasolines are collectively referred to as oxygen-
ated fuels. To meet clean air standards, some areas of the United
States and Canada use oxygenated fuels to help reduce emis-
sions.
If you use an oxygenated fuel, be sure it is unleaded and meets the
86 minimum octane rating requirements. Before using an oxygen-
ated fuel, try to confirm the fuel’s contents. Some states/provinces
required 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 contain-
ing ethanol may be marketed under the name gasohol.
CAUTION: Risk of property damage. 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
