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 the
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.
Emission Control System Information
Source of Emissions
The combustion process produces carbon monoxide, oxides of nitrogen,
and hydrocarbons. Control of hydrocarbons and oxides of nitrogen is very
important because, under certain conditions, they react to form
photochemical smog when subjected to sunlight. Carbon monoxide does
not react in the same way, but it is toxic.
