I have had my '04 Xf for almost a month now and I have taken it on a few road trips as well as use it as my daily driver. I can get 325 -360 miles before my gas light goes on. I have 4 other vehicles, two of which gets better gas mileage than this and the other two is a suv and pu. I did not buy this vehicle for great gas mileage,instead I bought it to enjoy the drive.
