isn't ethanol a type of alcohol (I mean that in the sense that it will mix with water). so you can pour a known amount of gasoline in water and the ethanol will sink to the bottom and the gasoline will remain on the top and you could probably see the line where the gas and water separate.

That's exactly how you test. The easiest way to do it is place 10 ml fuel and 10 Ml water in a 20 or 25 ml graduated cylinder. Cover & shake. Check a few minutes later. If you now have 9 ml gasoline then you had E10. If you have 8 ml you had E20, 7 ml is E30, and E85 would be 1.5 ml gasoline left.
Why is it that even though everybody talks about performance and mileage differences between straight gasoline and E10 that nobody can tell if one station's fuel is different than some other's based on performance?
Starting to make me wonder if the whole E10 thing is just psychological.
