Sorry but alcohol lacks the energy of gas and the main reason we have it in our gas is to fatten the coffers of the corn growing states. Even the EPA blew up because of the amount of environmental damage occurring to the streams and rivers near these corn field. But due to a strong "corn lobby", the applied money to the complainers and the public continues to get duped.
There is nothing beneficial about putting alcohol in our fuel. It attracts water and can make a mess of your fuel system. Some want to increase alcohol to 20% soon.
It is not illegal here and if you want to pay for alcohol free gas, it is available at the pump if you look around for it. I use it in the boat and jetski.

These discussions fascinate me. People buy a $90,000 vehicle, and say drive it 12,000 miles a year. If your average mileage is what mine is, about 13 mpg in mixed driving, that means you burn a little over 900 gallons of gas a year. In my area the price between regular and premium is about $0.50 a gallon, so you spend under $500 extra a year to burn the grade of fuel specified in the owner's manual. Why risk reduced performance and possible reliability problems for $500 a year, especially if you are a long term owner?

I cannot recall seeing an anecdotal post related to gasoline grade causing engine damage, reduced performance, and possibility problems, either here or on mud. If you've seen one or more, links to them would be outstanding and appreciated. I get the same mpg and 0 to 60 time with either 91 or 87 octane. Engine knock sensors and the ECU set timing for maximum hp without knock.
All that said, most of the time I run 91 octane...not because it needs premium, but since it's the only ethanol-free stuff for 10-15 miles. With that comes more BTU's per gallon, as well as virtually no degradation of rubber fuel lines. Side benefit is with around a dozen Stihl power tools, ethanol destroys the flexible fuel lines in a year or 2, especially if you store the tool without draining the fuel. Ethanol-free will keep over a cold winter with a tiny bit of fuel stabilizer.

Same here, but at first scheduled maintenance in spring and fall. That's maybe 5K.
This discussion is in a whirlpool, headed straight down.

No disagreement here!

And after 15 years of long-term ownership, I'll have $7,500 extra in my pocket.

And here is the crux of the problem. All we have is anecdotal evidence, which is no evidence. Until I see results which are repeatable and repeated by others, conducted in a controlled environment, e.g. on a dyno, then I'll follow the information in the owners manual for whatever vehicle I'm driving.
