Technical Consumer Information

Oxygenated Fuels

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:

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.

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”.

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 your fuel system.
