Gasolines containing alcohol
If you decide to use a gasoline containing alcohol (gasohol), be sure it's
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 methanol (methyl or wood alcohol) that does not
also contain cosolvents and corrosion inhibitors for methanol.
Never use gasoline containing more than 5% methanol, even if it has
cosolvents and corrosion inhibitors.
Fuel system damage or engine performance problems resulting
from the use of gasoline that contains alcohol is not covered under
the warranty.
Honda cannot endorse the use of gasoline containing methanol
since evidence of its suitability is as yet incomplete.
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
gasoline that contains alcohol, or one that you think contains
alcohol, switch to a gasoline that you know does not contain alcohol.
