I noticed about a 2 mpg improvement with the Celebrity after adding the airdam, and a similar loss when I took it off for awhile. Hard to say with the wagon, I haven't driven it much since adding the airdam. But since it is almost the same car and both undercarriages are the same (very dirty), I would think it should give a similar improvement with all else equal. I hardly drive it now, but will be driving it full time when winter starts.

Winter daily driver, parked most days right now
