    On average I get between 23 and 24mpg. Last tank was 23.3, best tank ever was 24.2.

    All stock, 2.73's. I drive with a pretty light foot most of the time, and do mostly highway.

    I got around 30 before major mods with the slushbox and 2.73's 90% of it was highway though. 80 MPH at about 1800 rpms was lovely.
