It can, however, be used in flex-fuel vehicles and those (mostly from GM) designed for E85 (85-15 gas-alcohol mix). If used in a flex-fuel car, however, it may be subject to a motor-fuel tax, which varies from state to state. I'm not enough of a lawyer to know all the details, but, in some cases, using homemade fuels without paying the tax on it is a legal offense.....people have been fined for making diesel biofuel at home and not paying the diesel tax on it.

The old saying that there are two certainties in life (death and taxes) didn't come about without reason.
