Petrol Containing Alcohol
If you decide to use a petrol containing alcohol
(gasohol), be sure its octane rating is at least as
high as that recommended above.
There are two types of gasohol: One contains
ethanol, and the other contains methanol. Do not
use gasohol that contains more than 10% ethanol.
Do not use gasohol that contains methanol
(methyl or wood alcohol) unless it also contains
cosolvents and corrosion inhibitors for methanol.
Never use petrol containing more than 5%
methanol, even if it has cosolvents and corrosion
inhibitors.
Engine performance problems resulting from the
use of fuels that contain alcohol are not covered
under the warranty. Honda cannot endorse the
use of fuels containing methanol since evidence
of their suitability is not yet complete.
Before buying fuel from an unfamiliar station, try
to find out if the fuel contains alcohol. If it does,
confirm the type and percentage of alcohol used.
If you notice any undesirable operating
symptoms while using a petrol that contains
alcohol, or one that you think contains alcohol,
switch to a petrol that you know does not contain
alcohol.
