warning
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 alternative fuels may cause performance prob-
lems, loss of power, overheating, fuel vapor lock, and unintended machine operation, including, but not limited to,
improper clutch engagement. Alternative fuels may also cause premature deterioration of fuel lines, gaskets, carbu-
retors 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.

adequate lubrication caused by failure to use an ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FD
certified oil, such as Echo
