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.
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.
