Nobody is talking about using E85 - they are only talking about using E10 which is the international standard anyway.
internal combustion engine compress gases. When you add ethanol (or lead or any other octane booster) that same engine will be able to compress the gas to a higher pressure. If you want to know more than that go onlne and read up on it. I'm sure you;ll find out all sorts of things you didn't know.
the addition of ethanol generally results in a reduction in fuel efficiency of about 3% - so if the only factor here was the amount of BTUs in the fuel then the addition of ethanol would result in a much greater degradation in fuel economy.
btw ethanol is also refined from crude oil
