FUEL STATEMENT
Gasoline -
Use 89 Octane [(R+M)/2] (mid grade or
higher) gasoline or gasohol known to be good
quality.
Gasohol may contain up to 10 % Ethyl (grain)
alcohol or 15 % MTBE (methyl teriary-butyl ether).

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.
Two-Stroke Oil -
A two-stroke engine oil meeting
ISO-L-EGD (ISO/CD 13738) and JASO M345-FD
Standards must be used.
ECHO brand premium Power Blend X™ Universal
2-Stroke Oil meets these standards.
Engine problems due to inadequate lubrication
caused by failure to use an ISO-L-EGD (ISO/CD
13738) and JASO M345-FD certified oil, such as
ECHO premium Power Blend X™, will void the
two-stroke engine warranty.
