10% Ethanol your not really going to see difference in overall performance and minimal lower MPG (like someone else said like 2% or so).

One thing I noticed on my Lexus LS when I replaced the starter twice, was the first time 10% Ethanol blend gas was at about 25% of the gas stations around. So not to often did I fill up with Ethanol blend. Second time when I replaced the starter though I'd say during that time and currently now around 90% of the gas stations use a 10% Ethanol blend and the intake manifold had alot more gunk/deposits in it. My buddy who was helping me (car nut) said he has noticed over the last few years as the Ethanol blend became almost a standard that most cars he has worked on he notice a lot more deposits built up in the intake manifold. Though by just spraying a little carb cleaner it cleaned right up with very little work. So I'd assume if you run a fuel injector cleaner through once every few months it should keep everything squeaky clean. Which is what I do now with my BMW and Lexus.

Oh well my 2 cents from my experience.
