Wasn't to long ago diesel was a lot cheaper than pump gas, too.I run alky on mt TTA, and E-85 on my supra. i like the E85 better, however my car is fitted with a flex fuel sensor and a bunch of other gadgets so i can just drive the car fill up whatever fuel i want and the ecm does the rest. i even have a gauge that displays exactly how much ethanol is in the tank! that being said E-85 with the addons is much better IMO, yea you use more fuel and need a bigger fuel system but at 2.05 a gallon you cant go wrong!
