WARNING
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.
IMPORTANT
• Echo brand 2-stroke oils may be mixed at 50:1
ratio for application in all Echo engines sold in
the past regardless of ratio specified in those
manuals.
• Use of unmixed, improperly mixed, or fuel older
than 90 days, (stale fuel), may cause hard
starting, poor performance, or severe engine
damage and void the product warranty. Read
and follow instructions in the Storage section of
this manual.

FUEL AND LUBRICANT

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 ap-
proved. 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 meet-
ing ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FD
Standards 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.
