Local gas station supplies 91 octane ethanol free. After expensive rebuilds on my lawn tractor and snow blower, and the loss of an outboard motor, I only use 91 octane for my small engines. No problems so far.
Believe me its worth the extra cost.
That’s what I do.
There is one gas staion in my are that sells ethanol free gasoline.
It is always at least $1.00 a gallon more than premium with ethanol.
I did the same a few years ago after talking to a guy on a tree crew. They were having many problems with their saws until they went ethanol free. I swear by it. My only gripe is the only way to get it here is 91 octane which is expensive. I use it in my lawn tractor, snow-blower. weed-eaters, chainsaws and my outboard. It adds up.
