My owners manual says to run 89 octane gas because it cleans the engine better. But I have heard that non-ethanol gas is better for single-cylinder engines. Any suggestions?

I use ethanol fuel in my Echo trimmer and have no problem. I do recommend using Opti-2 oil. Been doing this since I purchased it seven years ago and have never had a problem.

I use 87 ethanol fuel and Stihl synthetic 2-stroke oil. Keep fuel fresh, 30-60 days.

89 octane gas is fine; but, if it's going to sit idle for an extended period of time then I'd run it dry and not leave any is the system anywhere. That ethanol crap loves to eats stuff up in the off-season . . ..

Realizing that this is an old thread, I switched to Husqvarna pre-mix about 5 years ago, and it's completely done away with carburetor problems. Yes, I get it's more expensive, but there's something to be said for having equipment start the first or second pull. I would switch back to mixing myself, but I can't find any ethanol-free gas near me.

E0 all the way for homeowner use. I rarely have any fuel problems in any of my equipment. But I am also blessed to be able to buy it at the pump! Not all can!

You can make it from pump gas. There are videos on youtube about removing the water/alcohol if you like experimenting/tinkering.

If you don’t use much fuel, it’s more convenient to buy the canned pre-mix.

Mix my own using ethanol free fuel and Stihl synthetic.
