BTU is a unit of measurment for heat. Ethanol does not produce the same amount of heat (read: engergy) as gasoline. An engine running on Ethanol will get LESS gas milage because it takes MORE of it to run the engine. While its octane level is very high, something like 109, its power output is very low which is why you have to have more Ethanol fuel in the air mixture, which means less gas milage.
If we can produce a super ethanol that will yeild us the same power as gasoline, make it cheaper, cleaner, and more abundant, then the only thing we need to do with oil is change it every 4k miles or so.
BTW, Big Al is promoting the 4,000/4 Month oil change. Average car uses a gallon of oil every oil change. By moving from 3 to 4k miles, you save about a gallon of oil every year. If everyone in America went to 4k or more between oil changes, that would save 300 million gallons of oil.
Most new cars have oil life monitors, in which either a computer algorythm or by sensor can tell you when to change your oil. I know my Maxx was over 5k between oil changes. Some cars are said to do it every 10k.
Reduce oil use, which has to be disposed of somehow. At least gasoline is burned off. Oil has to be transported and all this other crap.
