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 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.
Oxygenated Fuels
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.
