there are multiple older threads about this...

where do you get 10% difference in fuel economy? if the fuel is 10% alcohol you dont lose 10%, the alcohol still contributes. i believe 10% alcohol fuel has about 3% less BTU, but the idea that it correlates directly to mileage has been debated. some even claim better mileage with 10% alcohol.
