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).
Gasohol containing methyl (wood) alcohol is
not
approved.
TWO-STROKE OIL -
A two-stroke engine oil
meeting ISO-L-EGD (ISO/CD 13738) and JASO
M345-FC/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-FC/FD certifi ed oil, such
as ECHO premium Power Blend X™, will void the
two-stroke engine warranty.
IMPORTANT
• ECHO premium Power Blend X™ Universal
2-Stroke Oil may be mixed at 50 : 1 ratio for
application in all ECHO engines sold in the past
regardless of ratio specifi ed 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.
WARNING
Alternative fuels, such as E-20 (20 % ethanol),
E-85 (85 % ethanol) or any fuels not meeting
above requirements are not approved for use
in ECHO 2-stroke gasoline engines.
Use of 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.
Alternative fuels may also cause premature
deterioration of fuel lines, gaskets, carburetor
and other engine components.
