There are several gas stations near me that sell ethanol-free premium gas. That's what I use in my 4-cycle lawn mowers and my 2-cycle weed trimmer. It's easy to mix the oil with the gas for the 2-cycle engine.

If you have leftover fuel at the end of the season you can buy fuel stabilizer to mix with the fuel and keep it from going bad during the winter.

Thanks.

It must be ethanol free and the proper octane, yes? That's the problem I'm running into.

Ethanol-free premium grade should work fine. The ethanol-free premium gas in my area is 91 octane. Regular unleaded gas here is 85 octane. The altitude here is almost 5,000 feet. The way I understand it is octane ratings need to be higher at sea level than at higher altitudes.

What i do is, pour the gas out of the machine back into the gas can, use a funnel. Once you've done that, run the machine till all the gas ran out. Add fuel Stabilizer to the gas can and store for the winter.

I also run my machine on an empty tank until it quits at the end of the season, but I think fuel stablizer is a waste of money since it's shelf life once opened is only a couple years. It's perfectly fine to pour whatever mixed oil/gas you have remaining once the season is over into your car's fuel tank if you don't want to waste it by dumping it on the ground.
I also think the premix cans of fuel are a total waste of money. You get 1/4 gallon for $6 which is absolutely ridiculous, and on top of that I've found that my 2 cycle leaf blower runs better on the pump gas. The only caveat is I wouldn't use gas with over 10% ethanol, but I've never had a problem using 85 octane regular fuel from sea level to 6,000 feet elevation.

You have E10 available? Here all pump gas is E15. I still prefer no ethanol, because of what it does to the rubber hoses and priming bulb. The $6 quart is worth it to me because I don't use that much for the chainsaw and mini-tiller anyway, it may last a whole season, and besides no ethanol it's 93 octane and has stabilizer in it already.

Dump the gas out, start it up and let it run dry. It won't run for over a minute on the gas left in the carburetor.

I want to recommend Red Line 2-cycle oil for air cooled engines. It's a full synthetic racing oil for 2-cycle motorcycles. I have a cheap 2-cycle leaf blower that gets a lot of use, blowing leaves, cleaning gutters, burning piles of brush, etc. One of the head bolts holds the handle, and the handle broke. After 2 years I pulled the head off to look at the cylinder, and it was white glove clean with no sign of wear or scuffing. I was astonished. NAPA sells it.

Yeah, the gas in my area (and areas I've lived previously) has no more than 10% ethanol. I don't let the gas sit in the machine year round, I think that's why I've never had a problem with rubber or carbs. I add the fuel first time I need the machine and drain it last use of the season for that tool and run till it stops. Since I started doing that many years ago I've never had a problem with any of the 2 cycle machines I've owned.

I would say it is not going to make a difference (87 vs 89). All our non-oxy here in MN is 91.
