Fuel
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.
Fuel Requirements
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 approved. Use of ECHO branded 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, such as ECHO branded 2-stroke 
oils, meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FD Standards must 
be used. ECHO branded 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 will void the two-
stroke engine warranty.
2-Stroke engine oil contains petroleum distillates and other 
additives that may be harmful if swallowed. Heated oil can 
release vapors that can cause flash fire, or ignite with explosive 
force. Read and follow the oil manufacturer’s instructions, and 
observe all safety warnings and precautions for handling 
flammable liquids. For more detailed safety and first aid 
information, visit www.echo-usa.com for a copy of the Material 
Safety Data Sheet.
