100 Octane Fuel

Does anybody use 100 octane fuel in their small equipment? My gas station stopped selling ethanol free fuel a couple years ago. I've seen the effects of ethanol at my local shop with other peoples equipment. I've had no issues yet... Right now our gas has 10% ethanol and heard it is possible to go to 15%-20% ethanol. Right now I'm running 93 in everything. I ran 100 octane all last year without a problem, and my small equipment started up easily in the spring. Its not exactly in my route to go get it often so I've just been getting 93 when I go fill my wright stander up. Yes I know 100 is more expensive...And yes I know the argument will start of it burns hotter, although I disagree. Just looking for some thoughts since I couldn't find any other threads when I searched. Thanks in advance.

Octane allows fuel to burn slower.

Click below to see if there are any gas stations near you that offer ethanol-free fuel.

I don't think the OP is concerned about the octane rating, rather he wants ethanol free fuel.

The only 100 octane fuel I know of is aviation gas, which is leaded. Leaded fuel will allow more carbon build up. Everything is a compromise. The link to search for ethanol free gas is probably the best bet for the OP.
