Petrol Containing Alcohol
If you decide to use a petrol 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 petrol that contains
more than 10 % ethanol. Do not use petrol
containing methanol (methyl or wood alcohol)
that does not also contain cosolvents and
corrosion inhibitors for methanol. Never use
petrol containing more than 5 % methanol,
even if it has cosolvents and cor rosion
inhibitors.
Fuel system damage or engine performance
problems resulting from the use of fuels that
contain alcohol is not covered under the
warranty. Honda cannot endorse the use of
fuels containing methanol since evidence of
their suitability is as yet incomplete.
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.
