You'll burn more E-85 becuase more is required to get the same amount of energy. Also, E-85 takes more energy to produce than straight gasoline. I wouldn't bank too much on this technology. It's a stopgap that the farmers are behind but in reality if all the corn produced by this nation was used to make this fuel, less than 25% of the nation's petroleum requirements would be met. If you want something that is really benneficial, go to diesel and run biodesel or get a waste oil conversion. It would probably pay for itself in the first year. Many restaurants would be willing to give you their oil for free simply becuase they're saving money by not having to pay for a recovery firm to come out and get it. While we're at it, support getting rid of regional gasoline mixtures. Go with one or two that are more efficient, like California's. Within 200 miles of St. Louis, 7 different formulas are used based on the season and the states' emission requirements. Go to one, and it reduces costs becuase refineries have to shut down and make adjustments for every fuel.

I think the only way to really do something about this is to come up with real alternatives to gasoline. However, with the profits oil companies are making these days it's pretty easy for them to buy the rights to better technology and horde it for themselves.

Also, what ever happened to efficient engines? I seem to remember cars getting a lot better fuel economy 10 years ago. Now GM touts cars that get 30mpg. That's not great.

Personally, I'll just keep riding my bicycle more, and use mass transit when I can. I'm finding the train ride to the airport is a nice break from reality. I read the paper, or just sit and enjoy the view of all those saps sitting in rush hour traffic, one to a car.
