I did a 300mile trip today. Here's what mine does consistently crushing in the freeway, with just an intake and cat back exhaust, no ecu tuning..

We drove our 2006 to Florida (from Chicago) back in 2009 and the best we saw was upper 13's but we were driving about 70-75mph. I don't see why you should not be able to get 13-14mpg's if you stay at 65mph. This past summer we drove up and spent a week in northern Wisconsin with the 2008 and I saw a best of 15.7mpg's on one fill up, averaged high 14-low 15 on the other fill ups. This was due to flat roads and speeds of around 60mph once we were up there. Also they don't have ethanol in the gas up there.

I agree... On a flat road on a mine hit 14's, your MPG varies on the road you drive into..
