There's a station near me which sells E-85 for about $0.30 cheaper than "real" [well 90% real, anyway] gasoline. Of course, since a gallon of E-85 won't move a car as far as a gallon of real gasoline, the gasoline is still cheaper per mile.
2 stations in Columbia Mo. I'm a wrench and I think its a good idea...great for keeping combustion chambers clean.
