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 certified 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 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.

   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.
