I don't know where you find non ethanol gas except the airport or race track, and I'm not paying their price!
Ethanol has it's advantages and disadvantages.
Advantage, the ethanol keeps water from collecting in the tank and rusting it, also keeps water from pooling and freezing, sends it right on through the engine. Ethanol works along with octane, burns cooler so lower octane works well with higher compression engines. Ethanol works very well with fuel injection and sealed systems.
Disadvantage, older neoprene fuel components are attacked by ethanol. Fuel pump diaphragms, non ethanol resistant hoses, carburetor diaphragms and other rubber components don't like it. They degrade, flake, and leak. Open systems, vented tanks, carburetors, engines that get seasonal use or stored are prone to fuel evaporation, which leaves sticky residue behind from the ethanol. It will slog jets, stick floats, stick needle valves, generally cause a mess in the fuel system.
As for high octane having any advantage, it should only be used where needed. It is only needed in high compression engines. Very few engines fall into that category. Some of the old muscle cars, some newer performance cars, some 2 cycle chainsaws. The owners manual is the best source for fuel requirements. Everything else will run just fine on low octane pump gas. Fuel quality and consistency has come a long way since the early days of gas engines. Some older equipment warns of using the proper octane fuel as the mfg had no control over where the equipment might end up, a foreign land where good fuel was unavailable, or someone attempting to run on "drip gas" or whatever was available or might save a dollar.
Running high octane in a low compression engine is not only a waste of money, it actually reduces the BTU value of the fuel, as octane displaces the otherwise usable fuel. It also contributes to carbon build up and crankcase deposits over the long run.

Today's Featured Article - 12-Volt Conversions for 4-Cylinder Ford 2000 & 4000 Tractors - by Tommy Duvall. After two summers of having to park my old 1964 model 4000 gas 4 cyl. on a hill just in case the 6 volt system, for whatever reason, would not crank her, I decided to try the 12 volt conversion. After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
