So what I am getting is they will either make no noticible improvment in gas mileage, or they will make some difference. If they make even a 1 or 2 mpg improvement in FE, then they would pay for themselves in 1 or 2 years.
Not sure if I want the kind that press on to the rims. I used to have pressed on hubcaps on my old 67 Mustang, and they were always falling off. I saw a screw on kind. Not sure what they screw on to though. Do holes need to be drilled into the rims or something?
