Fuel Requirements
Gasoline
- Use fresh (purchased within the last 30 days from the pump) 89
Octane [R+M/2] (mid grade or higher) gasoline known to be good quality.
Gasoline may contain up to 10% Ethanol (grain alcohol) or 15% MTBE
(methyl tertiary-butyl ether). Gasoline containing methanol (wood alcohol) is
NOT
approved. Use of ECHO branded fuel is recommended to extend
engine life in all air-cooled 2-stroke and 2/4-stroke hybrid engines.
Two Stroke Oil
- A two-stroke engine oil, such as ECHO branded 2-stroke
oils, meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FD Standards must
be used. ECHO branded 2-stroke oils meet these standards. Engine
problems due to inadequate lubrication caused by failure to use an ISO-L-
EGD (ISO/CD 13738) and J.A.S.O. M345-FD certified oil will void the two-
stroke engine warranty.
