For the record: ethanol burns with no carbon residue. All you want get is CO2 and water. Some countries run on E100 ethanol. Ethanol is used in drag and indycar racing, look it up.

Ethanol burns with 1/3 less energy vs gas, but much higher octane rating.

So while you will get 25% less fuel economy with E85, it costs less than half as much. But pickup drivers never math good.
