well every time i've driven through texas, i've gotten stopped by the cops. so i maintained a decent speed, besides my brother is driving my 240.

I have a 06 5AT sedan, I just drove from Baltimore to Jacksonville with a loaded trunk and got 27mpg on one tank, Left on a full tank, filled up after 449 miles and then still had a half tank when I arrived in Jacksonville. The only thing different from factory is a K&N drop in filter and synthetic oil.
