"real" gas or ethanol gas
I recently filled the tank on my 2013 Terrain with non ethanol fuel. It cost me $3.40 per gallon and the ethanol fuel was $3.00 per gallon. I don't know, I'm no math xpert but somthing just doesn't seem right. I mean, there'* only one gallon of ethanol in each ten gallons of gas. I'm not sure how to work it all out mathematically, it just seems like the math doesn't work to me.

gas value is more based on what they think they can get away with than what it costs them. where are you at, i would feel pretty good if i could get gas that cheap

Wish I had access to non-E gas myself.

i have tried that on occasion while traveling, the car certainly seems to run smoother. never really had the opportunity to do a direct comparison of MPG though

And I believe that this is the answer.
Those that have E10 all over the place, and are against the "evil of ethanol" would gladly pay a slight markup/premium to get ethanol free. This is also assuming the octane is the same, as some stations will only have ethanol free in higher octanes, and the higher octane alone is the driver for price. It could also be something to the effect of having to pay extra to get it shipped in from further away.
In my case, there is only one station in town that advertises ethanol free, and they directly complete with another gas station that is across the street that runs E10, and they are usually the same price.

Locally I only run Chevron 94 Octane ethanol free and it cost about $6 per gallon.
My vehicles do get better mileage and run better with the higher octane.
The main advantage and peace of mind is knowing that I wont have water absorbing ethanol in my tank and fuel lines and tank wont rust out.
I always keep the vehicles tanks full especially as it get'* colder outside, to prevent condensation in tank.
Here is one of my local Favorite Chevron Stations!
Located at Coal Harbour in Van BC on Pacific Ocean, I am just reversing as the Fire boat is getting re-fueled.

I've also heard, if you were to mix 10-15% water with 1 gallon of E85, mix/stir shake whatever and let settle, you can drain off the bad mix in the bottom and have 99%gasoline.

My bad, its the other way around. 85%ethanol and 15% gasoline. No wonder my L67 runs like lately.
E85 - Wikipedia, the free encyclopedia
Corrosion in non-E85 fuel systems
Use of gasoline in an engine with a high enough compression ratio to use E85 efficiently would likely result in catastrophic failure due to engine detonation, as the octane rating of gasoline is not high enough to withstand the greater compression ratios in use in an engine specifically designed to run on E85. Using E85 in a gasoline engine has the drawback of achieving lower fuel economy, as more fuel is needed per unit air (stoichiometric ratio) to run the engine in comparison with gasoline. The additional ethanol required for a stoichiometric fuel ratio helps compensate for lack of energy provided by ethanol'* lower heating value (LHV), which is lower than the LHV of gasoline.
Fuel systems and engines not designed or modified to use E85 may experience increased wear and may fail prematurely. Some (particularly older) fuel systems and those used in powersports and agricultural engines contain rubber seal elements which have excellent gasoline resistance but poor ethanol resistance. These systems generally can accept up to E10 without major degradation in service life of susceptible seal components.
