Does anyone know if those wind deflectors have any effect on gas mileage .. Will these deflectors give you better gas mileage and if so how much

For a SUV or pickup with a shell, putting the deflector all the way back can net decent mpgs, 5ers are so far from the cab wall (VS height above cab roof) it is near impossible to gain beyond a few tenths of a mpg. Most people can save that much by slowing down 2-3 mph.
