TECHNICAL AND CONSUMER INFORMATION

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.
