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:

ETHANOL-

(ethyl or grain alcohol) 10% by volume

You may use asoline containing up to 10% ethanol

by volume. t! asoline containing ethanol may be

marketed under the name “Gasohol”.

MTBE-

(methyl tertiary butyl ether) 15% by volume

Tz;feay use gasoline containing up to 15% MTBE by

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.

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.
