I just got back from a 250 mile run with my '08 and I have to ask: Is it just me or is everyone getting 22.3 mpg? I took the Chally up I-70 here in Colorado over the steepest and highest miles on all of I-70 and got that mileage. If there is not a problen with my mileage computer then why are Challys rated at 13-18 by the EPA? I travelled at 80 for most of the way with short bursts to over 100 (I'm a baaad boy). I was also starting at 6000 foot altitude and ended at 10,000 foot altitude. So I don't baby it but it is one of the highest mileage vehicles I own. Am I the only one?
