Very true, but the statement is that it affects gas mileage, I suppose that an alternator that is full fielding might increase the load slightly, but not something I would think you could see in your gas mileage.
I think it’s plausible that a weak link in that spark side of the system could cause the plugs to not fire at their full potential and not burn the fuel efficiently.
