If we push our electromechanical knowledge (and our imagination) a little bit we can see the possibility of a defective ground point in our car forcing the alternator to overcome the current resistance caused by this by increasing its output and thus making the engine a little bit more strained trying to keep up with the alternator demand... there is your increase of gas mileage.

Maybe (I am not sure, I will be checking this out...) that was the old way of the alternator functioning, before better gounding (less resistance) wiring materials and "smart" alternators controls of nowadays...
