If you decide to use a gasoline containing alcohol ("gasohol"), be sure the octane rating is at least as high as that recommended by t w o types of
"gasohol" one containing ethanol, and that containing methanol.
Do not use gasohol that contains more than gasoline containing methanol (methyl
10% ethanol. Do not use
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: use of such fuels are not covered under Power Equipment Warranties.
Honda cannot endorse the use of fuels containing methanol since evidence of their suitability is as yet incomplete.
Before purchasing fuel from an unfamiliar station, try t o confirm any undesirable operating symptoms after using a gasoline that you does not contain alcohol.
