I have an 04 Impala w/3.4L
I don't see much of a mileage hit from using E10, and it's cheaper than regular unleaded, so I use it. Over the last two weeks, my mileage went from ~24MPG to ~27MPG. I fill up about once every 5 days.
I did not change anything on the car, nor my driving style. THe temperature has also been about the same.
I know that regular unleaded has a winter and summer mix, but does E10 also have a different winter formulation?
Oh, I am in the midwest, if that makes a difference.
