e85 is america flex fuel. 85% ethonal and 15% unleaded gas.
it is the renewable fuel that is being produce in the midwest from corn.
gm ford and chysler are all on board developing new engines that can run on e85 or on unleaded fuel. running e85 makes more power so you use more fuel so the down side is that fuel mileage is decreased. about 20% how ever that is why e85 sould be 20- 25% less at the pump. some market realize this and market the price corect and other markets don't.
in my market they are tring to sell it at the same price as unleaded around 2 bucks a gallon. but with in 30 miles away it is as low as 1.75 to 1.85 a gallon.
