Oxygenated Fuels
Some gasoline are blended with alcohol or an ether compound to increase the octane. These
gasoline are collectively referred to as oxygenated fuels. Some areas of the United States use
oxygenated fuels to help meet clean air standards. If you use an oxygenated fuel, be sure its pump
octane rating is 86 or higher.
Ethanol (ethyl or grain alcohol)
Gasoline containing more than 10% ethanol by volume may cause starting or performance
problems. Gasoline containing ethanol may be marketed under the name “Gasohol".
Methanol (methyl or wood alcohol)
Gasoline containing methanol must contain cosolvents and corrosion inhibitors to protect the fuel
system. Gasoline containing more than 5% methanol by volume may cause starting and/or
performance problems and may damage metal, rubber and plastic parts of your fuel system.
MTBE (methyl tertiary butyl ether)
You may use gasoline containing up to 15% MTBE by volume. Before using an oxygenated fuel,
try to confirm the fuel’s contents. Some states (provinces in Canada) require this information to be
posted on the pump. If you notice any undesirable operating symptoms, switch to a conventional
unleaded gasoline. Fuel system damage or performance problems resulting from the use of an
oxygenated fuel are not ours responsibility and are not covered under warranty.
NOTICE
Oxygenated fuels can damage paint and plastic. Be careful not to spill fuel when filling your
fuel tank. Damage caused by spilled fuel is not covered under warranty.
