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 con-
taining methyl (wood) alcohol is NOT approved.
TWO-STROKE OIL - A two-stroke engine oil meeting 
ISO-L-EGD (ISO/CD 13738) and JASO M345-FD Stand-
ards must be used. ECHO brand premium Power Blend 
X™ Universal 2-Stroke Oil meets these standards. En-
gine problems due to inadequate lubrication caused by 
failure to use an ISO-L-EGD (ISO/CD 13738) and JASO 
M345-FD certied oil, such as ECHO premium Power 
Blend X™, will void the two-stroke engine warranty.
 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 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.
