Welcome to Ecomudders!

A couple of years ago I stopped to fill up our TDi in Santa Cruz (on the coast west of San Jose), and a guy pulled up to the next pump with a diesel powered older soft-top Jeep (CJ-5?). We got to talking and he claimed 30 mpg on the highway at 55 with its VW 1.6L TD and (IIRC) a Toyota tranny with a super-tall 5th gear. Sorry, don't recall much additional detail.

On the aero side, be sure to read MetroMPG's thread on Autospeed article: adding a chin undertray to a 1st gen Prius. A 4wd Jeep has to be a lot "dirtier" than a Prius, so should have proportional benefits from cleaning up the airflow even a little.
