The engine must apply unleaded gasolinge with an octane number over 86. Using unleaded gasoline
will decrease the possibility of poducing carbon deposit and prollong the engine's service life.
Never apply used or polluted gasoline or a maixture of gassoline and engine oil. Make sure the fuel is
free ofdirt and water.
2. GASOLINE CONTAINING ALCOHOL
If you decide to use a gasoline containing alcohol( fule blend), be sure its octane rating it at least as
high as that recommended by the company. There are two types of "gasohol". One contains ethanol,
and the other contains methanol. Neither gasoline containing more than 10% ethanol nor 5% methanol
is allowed to be used. If methanol content in the fuel blend exceeds 5%, it may bring bad eff ect on the
engine performance, besides, it may damage metals, rubber and plastic parts.
