With gas prices crossing $4 a gallon, the EPA says cheaper, more ethanol-rich fuel will ease the pain. The math doesn't really add up—but the risks sure do.
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.

It varies by area. My E85 is well above half e15. Like within a dollar so at recent best, 33% less.
