Fuel

Diesel fuels and alternative fuels, such as E-15 (15% ethanol), E-85
(85% ethanol) or any fuels not meeting ECHO requirements are
NOT approved for use in ECHO 2-stroke gasoline engines. Use of
diesel or alternative fuels may cause performance problems, loss
of power, overheating, fuel vapor lock, and unintended machine
operation, including, but not limited to, improper clutch
engagement. Diesel or alternative fuels may also cause premature
deterioration of fuel lines, gaskets, carburetors and other engine
components.
Fuel Requirements
Gasoline - Use 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. ECHO brand Power Fuel is 93 octane, ethanol-free
®
fuel premixed with ECHO Red Armor engine oil at 50:1 ratio. Use of ECHO
™
Power Fuel is recommended to extend engine life in all air-cooled 2-stroke
and 2/4-stroke hybrid engines.

inadequate lubrication caused by failure to use an ISO-L-EGD (ISO/CD 13738)
™
and J.A.S.O. M345-FD certified oil, such as Echo premium Power Blend X ,
will void the two-stroke engine warranty.
