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.
