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
€PA
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
volurne.
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.
