OE Roof Rack Crossbars...mpg?
has anyone proved that removing them helps mpg? I have read that some people get alot of mpgs out of removing them, but I just can't see that they screw with economy that much!

I can't imagine that they screw too much with MPGs. The aerodynamics are already so bad I just can't believe it. My four lights didn't really effect it too bad.

I tried this for 2 months. It only improved by .5-1 mpg. def not worth not having its utilitity. you could gain that by raising tire presure 1-2lbs.

I think only big aftermarket ones would. Im running a Confer rack with 4 Hellas and a spare up top an that would help to take off. But not the thin stick bars

Maybe not measurable for some, but still not magic.
