Anything without ethanol should have a higher energy content. I'd roll with that and see if you get any more MPGs. That would affect your mileage.

Here in PA, Shell's V-power, which is a top tier brand with tons of detergents for cleaning valves and whatnot used to not have 10% ethanol. Now it goes, as the state has regulated that ALL pump gas contains at a minimum 10% ethanol.

Also, BP is a top tier brand. If it contains no ethanol, I'd surely roll with that. Best of both worlds.
