ADDITIONAL 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
USA 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
MTBE ––––––––(Methyl Tertiary Butyl Ether) 15% by volume
METHANOL ––(methyl or wood alcohol) 5% by volume
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 the Distributor's Limited Warranty
(page 52).

You may use gasoline containing up to 10% ethanol
by volume. Gasoline containing ethanol may be
marketed under the name "Gasohol".
You may use gasoline containing up to 15% MTBE
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.
