I was just watching a review of ethanol energy on CNN. They report that Consumer Reports claims that cars using ethanol see no decrease in mileage or performance. Now I'm not sure what Consumers Reports claimed and a source wasn't cited, but the point of the story was to consider the performance of ethanol compared to gasoline, which was left somewhat vague in the end. Gasoline has about 125,000 BTUs per gallon, and ethanol has about 76,000 BTUs per gallon. The last time that I checked, the conservation of energy law was still in effect. Sidebar: IMO, nothing that Consumer Reports claims can be believed. This is not the first time that I have run across this sort of nonsense. In fact, just about anytime that I see a report from them on something that I happen to know about, they're wrong.
