The best part about the fuel here:how the decline in quality and rise of prices began. Once the politicians got involved, the industry had to put 10% ethanol in the fuel as an emissions reduction measure. That's what they said on our news channels; but if you watch CSPAN, live near Washington D.C., or read like a madman you also heard about the farming industry hitting dire straights 6-7yrs ago. The farmers were having to pimp-out their acreage to the government and told to plant corn under the program they were on. The corn helped the farmers, who helped the oil/fuel industry "clean" up their fuels a tad, who helped the manufacturers start getting towards their mandated CAFE standard in time, so we the consumers could feel better about not killing the earth.

Only real hiccup was the cars; they weren't engineered to run that concentration so until a model year (or two for some mfgs) later the new cars weren't either... all those vehicles running around on a fuel with less caloric energy to burn. The prices went up, the cars burn the stuff faster; and they industry made billions upon billions.

And for all the push for cleaner fuels and vehicles; you sure don't see enough E85 stations (or a good consistent %, that's made some of the racers carry sight-glass hygrometers around to test the stuff before they pump it). There was/is research into bacterial bio-diesel, so hopefully the nerds of the world can synthesize something gasoline cars can run on. I don't EVER want to stop driving mine!
