FUEL STATEMENT
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 Red Armor™ Fuel (Power Fuel™) is 93
octane, ethanol-free fuel premixed with ECHO Red
Armor™ engine oil at 50:1 ratio.
Use of ECHO Red Armor™ Fuel (Power 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 meeting
ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FD Stan-
dards must be used.
Echo brand 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, such as
Echo brand 2-stroke oils, will void the two-stroke
engine warranty.
