Yes, I run 50:1 in all of my 2 cycle chainsaws, never ever came remotely close to scoring a piston or burning a hole in top of one.
They run so much better on non Ethanol fuel too. Start way easier and run way better and more power.
The Ethanol fuel draws moisture just sitting in the tank and when you have the gas cap off, and in your gas cans too. Hence the moisture condensing back out dripping out of your cold exhaust pipe.
