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.

Any sensors will be insulated from the block and have their own ground wire from the ECU. They will not be affected by the potential of the block swinging.
Better spark would be hardly measurable in FE unless he had 12% misfires.
