There is definitely a difference in the winter blend and the summer blend gasoline. Most of the formulational changes are to help cold start by varying the fuels vapor pressure and the ease that it atomizes in colder winter temps.

No matter how expensive ethanol is its still cheaper than the gasoline based additives that would be substituted if that 10% mixture of E wasn't used. I doubt the rising cost of E has anywhere near the effect on gas prices as much as the rising cost of crude oil.
