Amazing you can even find ethanol free these days - I would buy whatever is cheaper. You might get slightly better mileage from the ethanol free stuff as it has more energy density than w/ 10% ethanol but probably not even noticable.
All modern stuff is tuned to run on E10 just fine.

You should get around 5% better mileage with 100% gasoline than you will with 10% ethanol. Around here 100% is easy to find, but at a 40% premium price over the 10% ethanol. It doesn't pay to get the 100% stuff. And modern vehicles are designed to run 10% ethanol, so the slight improvement in mileage is the only advantage. It's not worth the money.

many places in the Mid West ( corn country) you cant get regular 100% gas... Almost EVERYTHING is 10%... I bought a new F250 in 1989 and ran it 250K miles on 10%.. EVERYTHING I have bought since then runs on 10%.

If you have small motors (lawn, etc.) or boat motors (probably built up until about 2008) and other small motor applications, then the ethanol free is essential. The rubber fuel lines in these motors will deteriorate quickly especially if you leave any fuel with ethanol in them for an extended period. And it can be hard to get it all out, stabilizer doesn't matter. Speaking from multiple experiences here. Otherwise, modern vehicles probably have little benefit from pure gas. Although I have noticed an uptick in both pep and fuel mileage when I have it used it in late model trucks.

You can find ethanol-free gasoline in quite a few places in the midwest, surprisingly. Or maybe not so surprisingly.
https://www.pure-gas.org lists stations state by state that carry it. I don't really have a problem with it per se, but it doesn't store as well and tends to attract water. It has a benefit of not freezing up as readily because small amounts of moisture are absorbed. If you run gasoline powered equipment, especially two-stroke, you probably know about the potential problems of ethanol laced gasoline. It's not practical to try and avoid it completely but if you don't drive much or have collector cars the straight gas with stabilizer is a better choice for storage.

Correct. The system was designed to work with ethanol.

I didn't mean you cant find it if you look real hard, but it is not common in Illinois.. WE have 104 counties in the state and your site lists 125 gas stations. So basically one per county. The 3-4 small towns around me are not listed on the site. Springfield is a city of 100,000 people and they list ONE station. Quincy is a city of 50,000 and they list TWO stations.. I guess you can find regular gas if you look hard enough, but I would have to drive 30 miles and pay 20% more to get it. Point is I have been using 10% for over 30 years in a dozen vehicles / tractors / mowers / chain saws/ and few little problems.

I run premium in my Raptor and luckily the Texaco down the road has ethanol free premium. I actually run it in my Mustang and my rzr, too. The Raptor is not flex fuel, so I'd assume there could be some long term effect by using even the 10%stuff. An ounce of prevention and all...

ALL MOTORS will run 10%... a FLEX FUEL will run 85% ethanol... Mark was just pointing out that you can run 10% or ethanol free, your motor don't care, and neither will hurt......... I have been doing it for 30 years.
