Specifications
For best results, use only clean fresh, regular grade
unleaded gasoline. Use fuel with a minimum octane
rating as designated by the following:
Antiknock Index (Average of Research
86
Octane Number and Motor Octane Number)
Unleaded fuel is recommended since it leaves less
combustion chamber deposits. Oil must not be mixed
with fuel.
If using a gasoline containing alcohol (gasohol), be sure
the octane rating is at least 86 (Antiknock Index). There
are two types of gasohol: one containing ethanol, and
another containing methanol.
Do not use gasohol that contains more than 10%
ethanol. Do not use gasohol 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.
NOTE
Fuel system damage and engine performance
problems resulting from the use of such fuels are not
covered under Warranty. Honda cannot endorse the use
of fuels containing methanol since evidence of suitability
is as yet incomplete. Before purchasing fuel from an
unfamiliar station, try to confirm whether the fuel
contains alcohol, and to what percentage. If any
undesirable operating symptoms are noticed after using
a gasoline that contains alcohol, or one that contains
alcohol, switch to a gasoline that does not contain
alcohol.
NOTE
Discontinue use of any gasohol or alcohol/gasoline
blend if engine performance or fuel system problems
occur. Do not use such fuel unless it is UNLEADED.
Use fresh gasoline to ensure it is blended for the season
and to prevent the formation of gum deposits which
could clog the fuel system. Do not use gasoline left over
from the previous season.
