A 50:1 ratio with 89 Octane fuel can be used in all ECHO 2-stroke equipment, provided the oil is ISO-L-EGD and JASO M345 FC/FD certified. ISO-L-EGD and JASO M345 FC/FD oil must be used with a mid-grade (89 octane) or premium gasoline in all 1997 and newer engines.
A 50:1 Ratio = 1 US Gal. 89 Octane + 2.6 fl. oz. ECHO POWER BLEND OIL
Echo Power Blend Universal
2-Stroke Oil can be used in all of our 2-cycle air-cooled equipment ever
made. You may also use this oil in any other brand of 2-cycle air
cooled equipment, but it should always be mixed at the 50:1 ratio
whether or not it was a 32:1 or 16:1 etc. machine. This oil is the
highest quality 2-cycle oil on the market today. There is no need to
have more than 1 tank of fuel for your 2-cycle equipment any more.
