Mileage; Mythbuster?
All right, I would like some help.
My wife told me that she was watching a program where they claimed that washing your car and waxing it was something people should do, to get better gas mileage.
She said the program claimed that their is a 7% improvement in mileage, if you wash your car and keep it waxed.
I would not doubt that their might be a improvement, but their is no way that I can believe it would be 7%. I think the article was sponsored by Turtle Wax?
Does anyone have any ideas of what this figure might really be?
