When did it become American bashing to say America can't violate the laws of physics?
I don't work for Exxon, and I'll tell you that ethanol as a primary fuel source for automobiles is a pipe dream. We can make biofuels work (biodiesel is very promising) but there just isn't enough corn out there for ethanol to replace gas.
I keep whining about ethanol and gasoline blends reducing Miles Per Gallon, but no one listens. This is the real reason it's a big fraud. All oxygenates have a lower energy content than hydrocarbons.
I always record fuel economy every tank because it is an easy way to keep track of the car's condition. Prior to 10% EtOH additions, I got 30 MPG...I drive all highway. I now get 27. Where are the savings? Even if the 10% EtOH were cheaper, I would be buying more to go the same distance.
The is the dirty little secret.
