Gasoline spoils very quickly depending on factors such as light
exposure, temperature and time.
In worst cases, gasoline can be contaminated within 30 days.
Using contaminated gasoline can seriously damage the engine
(carburetor clogged, valve stuck).
Such damage due to spoiled fuel is disallowed from coverage by the
warranty.
To avoid this please strictly follow these recommendations:
Only use specified gasoline (see page
Use fresh and clean gasoline.
To slow deterioration, keep gasoline in a certified fuel container.
If long storage (more than 30 days) is foreseen, drain fuel tank and
carburetor (see pages
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 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 gasoline that contains alcohol, or one that you think
contains alcohol, switch to a gasoline that you know does not
contain alcohol.
