I'm running 33's on a stock D35 and D30, my best guess is 3.XX something gears, I don't know for sure.
I've owned the XJ for about eight years now, originally it got about 17-20 MPG. The engine failed and was replaced with a remanufactured engine and got about 15 MPG on the highway. After installing the lift, I'm getting no better than 10 MPG highway.
I can kind of understand the differences between the stock engine and reman engine, with the pistons having to be bored out and what not, but I don't understand how that makes a 5 MPG difference...
I can kind of understand the added weight of the lift and tires sucking fuel, but not another 5 MPG difference...
I've read about builds with lifts larger than mine, where the user gets in the 17 MPG range. I also have friends who have tracked something along 6 MPG fully kitted out. Any of you more experienced gear heads have any tips or thoughts to clear up my confusion and improve the fuel economy of my rig?
