I have only driven the Kia in town the past few days and have 115 miles on this tank so haven't got to check it yet. I will be taking it on a trip this weekend for about 350 miles. Dennis, I may be interested in the spacer after I see how the mileage thing pans out. I know I don't want to lift too much but 2 1/2 inches with 30" tires may be what I'm after. I will be driving it alot so i don't want to kill my fuel mileage but if I can still get in the 20's I'll be happy. One of the main reasons I sold the Jeep was that it sucked the fuel. Also didn't have much room.
