Fuel without ethanol?

This guy does a lot of neat stuff.  Here, he does the first of a series of tests comparing ethanol fuel to non-ethanol fuel:

I'll have to check that vid when I have a few minutes, to see if my suppositions are correct.
With that said, some of the local stations are starting to carry ethanol free gas (most notably, the Ingles near my house) but it's ~$1 more than regular E10.

Well, at ~5% (multi-cylinder engines) greater fuel economy, more power, and lower maintenance, it's probably worth that.  So, $1 more is the actual price of fuel, compared to non-ethanol fuel years ago at $0.76/gallon.

Without the ethanol, they do have to add octane.

This past weekend, I ran a 1 tank with ethanol fuel, followed by a tank without ethanol.  Two days later, I ran a tank without ethanol, followed by a tank with ethanol.  This was on the same stretch of road.  The non-ethanol fuel cost $0.31 more per gallon.  Although the engine temp remained the same, the thermostat opened about 200 more times on the ethanol fuel, than on the non-ethanol fuel.  I used .7 gallons less fuel with the non-ethanol fuel.  The fuel runs were 296 miles with the ethanol, and 291 miles with the non-ethanol fuel, just because of where the stations were.  I'd say that's a reasonable sample distance.  All 4 runs were with the AC on.  I got 4 MPG better fuel economy with the non-ethanol fuel.

Over the last several weeks, I have run 7 tanks of ethanol fuel, with the AC on, and got about 31 MPG, each tank.  I ran 285 or more miles per tank.  That is consistent, and should serve as a baseline.
