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 USA 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 51).
