FUEL
Fuel Requirements
Gasoline - Use 89 Octane [R+M/2] (mid grade or higher) gasoline
known to be good quality. Gasoline may contain up to 15% MTBE
(methyl tertiary-butyl ether). Gasohol containing methyl (wood) alcohol
is NOT approved.

Universal 2-Stroke Oil meets these standards. Engine
problems due to inadequate lubrication caused by failure to use an
ISO-L-EGD and J.A.S.O. FC certified oil, such as Echo premium Power
Blend

, will void the two-stroke engine warranty. (Emission related
parts only are covered for two years, regardless of two-stroke oil used,
