Snow, sorry to have to disagree with you, but you are mistaken. Ethanol, (and E85), engines not only can match gasoline on a miles per liquid gallon basis, they can beat them. The corn growers lobby used to give several colleges a new truck and let the kids convert a gasoline truck over to ethanol. The colleges that won the competitions always got better mileage on E85 than the stock truck did on gasoline. When you keep in mind the fact that ethanol has about 2/3rds the BTUs as gasoline, and still the kids were able to not only match but exceed the gasoline mileage, that tells me that it CAN be done. I don't think there is an 'Ethanol Vehicle Challenge' anymore, the car manufacurers have got it all figured out now. There just has to be enough demand, and I believe you'll see it in a few years, and Ford will be selling E85 only trucks that get the same fuel mileage as gasoline trucks do. DF
