He doesn't gain MPG from freeing up wasted electricity; he restores it from having better signals from his sensors, better spark and the like. Just cleaning the ground connections is usually enough, but replacing things would freshen them up as well.

Cleaning grounds is a normal practice in the geo metro community. It made one heck of a difference to my Miata, and my Ranger was doing all sorts of weird things before I cleaned it's grounds, like trying to die when I turned on the turn signals. Restoring power and MPG is just one reason to do it.
