I haven't had any worse gas mileage or performance....Most gas stations have been running 10% ethanol for alot longer than they've had the stickers. I think maybe you're imagining things, or maybe you just need a tune up

It isn't any cheaper becasue the corn has to be planted, harvested, trasported to process, processed, and transported to distribution. Every one of those steps uses gasoline/diesel, thats why the oil companies are supportive of E85.
