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. Do not
use petrol that contains more than 10 %
ethanol.

The use of petrol containing more than 10 %
ethanol may:
• Damage the painting of the fuel tank.
• Damage the rubber tubes of the fuel line.
• Cause corrosion of the fuel tank.
• Cause poor drivability.
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.
