GASOLINES CONTAINING ALCOHOL
If you decide to use a gasoline containing alcohol (gasohol), be sure its
octane rating is at least as high as that recommended by Honda.
There are two types of ''gasohol'': one containing ethanol, and the
other containing methanol.
Do not use gasohol that contains more than 10% ethanol.
Do not use gasoline containing more than 5% methanol (methyl or
wood alcohol) and that does not also contain co-solvents and
corrosion inhibitors for methanol.
Fuel system damage or engine performance problems resulting
from the use of gasoline that contains more alcohol than
recommended is not covered under the warranty.
Before buying gasoline from an unfamiliar station, first determine if
the gasoline contains alcohol, if it does, find out the type and
percentage of alcohol used.
If you notice any undesirable operating symptoms while using a
particular gasoline. Switch to a gasoline that you know contains less
than the recommended amount of alcohol.
