I am currently cruising around in a '92 XJ with about 245k on the original drivetrain, and I have been averaging about 17mpg in mixed driving. Still working on the tuneup - no idea how old plugs and wires are, and there is a decent sized crack in the exhaust manifold, so plenty of room for improvement there. In a 95% highway trip I took last month to upstate NY I got about 21.5mpg.

My '96 with 1/2 the miles that has 3.5" lift, 31s, 4.10s, aftermarket bumper, etc typically averaged 15-16, and got a best of 19.8mpg.

Maybe you should look into getting a stocker, just doing a budget boost (2"-2.5") and going with a 30x9.5 tire. Still has a nice look, plenty capable off road, no need to regear axles, and should still net you decent mileage (especially on the highway with the taller tires).
