NOTICE: 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.

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, 

carburetors and other engine components.

 

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 alco-

hol) is NOT approved.

Two Stroke Oil - A two-stroke engine oil meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FC/FD Standards must 

be used. Echo brand premium Power BlendX

 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 J.A.S.O. FC/FD certified oil, such 

as Echo premium Power BlendX 

TM

, will void the two-stroke engine warranty.
