I just got the warning that I have 9xx miles before no start. I've got 3050 miles on mine now. Why should I have to fill so soon? We did get this warning as we were travelling thru the eastern Sierras with chain controls in effect. It got down to 10 degrees. Btw, the X handled like a dream! I've had it now for 3.5 weeks and have driven it a lot. Love it! I'll be taking it in tomorrow.
