Key word here is "LEGALLY".
The only way to know is test it.
The percent of ethanol may be incorrectly added by the local fuel distributor or gas retailer. Overblending and "double-blending" is common. Adding 15, 20% or higher amounts of ethanol- (Legal limit=10%). Distributors do this all the time to raise their profits since Ethanol is subsidized and costs them less.


HOW TO TEST FUEL
FOR ETHANOL

This is a way that private airplane pilots sometimes use.

To determine if ethanol is in the gas:

On a test tube or olive bottle six or seven inches long, make a permanent line about two inches from the bottom.
Fill with water to this line, then fill the tube to the top with gasoline.
Cover the tube, agitate it, and let it stand.

The ethanol and water will mix and separate out together. If the water level appears to have increased, the fuel contains ethanol and should not be used. Ethanol percentages of less than 5% can sometimes give a reading below the line. Therefore, any deviation in the water line indicates the presence of ethanol and should serve as a basis for rejecting the fuel.

Has anyone noticed ethanol free fuel around the Lake Lavon and Sam Rayburn area's by any chance ?

you might consider having the non-ethanol gas you buy from the station tested to see how much ethanol is actually in it.

Some stations cheat a little.

Cheat? No way. Just because I put 27 gallons in my 25 gallon tank that wasn't empty yet because I drove into the station and a person would think that somebody had messed with the pumps?
How is that cheating? BTW this station is owned and run by foreigners. Did I report it? Oh hail yeah!
Another time on the way to the deer lease we stopped in Sweetwater to fill some 5 gallon gas cans to take down and they each held 6.5 gallons. My buddy didn't figure it out until we were already on the road again.
Naw, gas stations don't ever cheat
