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 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.
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 the Distributor’s Limited Warranty (page 56).
