Any of the premix stuff is great for folks who don't run a two stroke much. It has no ethanol and a long shelf life. You can also leave it in the machine with no bad effects.This is where Tru Fuel shines, takes the guess work out of mixing.
Not good for me because I'll run gallons through my saws and the premix is pricey. I am able to buy 91 octane non-ethanol and mix 40:1 with either synthetic Stihl, or Husqvarna oil.
Outboard water cooled two stroke oil is no good for a chainsaw, or trimmer! But for the average homeowner who just uses occasionally it will keep the machine alive for awhile. Most of the old two strokes are lower rpm and could run longer on just about any oil.
I spend more time with a chainsaw than I do on a tractor. I run high performance, high rpm saws and get years of service using the right mix!
Any old mix air cooled or water cooled mix gets dumped into the 4 stroke ridding mower,...
