In my opinion when you lift and modify your vehicle your milage will drop no matter what.
I bought my XJ brand new with 6 miles on it and I got just what the sticker said I would get for milage. 19 hwy and 15 city. Now that I am lifted I get about 14-15 hwy and in the city...well I really dont care. Anyways remember that we drive the most un-aerodynamic vehicles next to the Scion XB and when you raise it further in the air and add more weight from things like heavy duty bumpers and winches, rock sliders and roof racks it all adds to alot of drag. My new Good Year MT-R with kevlar tires weigh a staggering 67 lbs each including the rim! My old 225/75/15's weighed in at a mere 25 lbs and that was with the more rugged Bridgestone Duellers. Our cars are not light to begin with either. I had mine weighed once at a scrap yard and it weighed 4400 lbs. Mine is the sport model which is a more stripped down version of the Laredo. No fancy power windows or locks. No permium sound system or power leather seats. I would venture a guess all this would easily add a few hundred extra pounds to the equation. My vehicle has 3.55 gears and they are probably the best factory set of gears for running around town and having an overall good daily driver. I plan on getting 4.56's done this winter whilst the car is sleeping comfterbly in her auto cocoon and when that happens I plan on my milage getting worse...much worse. But I really dont care, for that is the price that I am willing to pay for having fun...a whole lot of fun. Of course I could try this and bolt on that. Maybe it will work and maybe it won't. You can bet I'd rather be sticking my money in my tank than under my hood. Just my $0.02 on the matter.

if you want good mileage, park the XJ (unless you're going wheeling) and drive a subcompact car.

Don't go wheeling with said subcompact car. Trust me.

We bought a 1987 Toyota for $100 and took it wheeling at my buddies sand pit. It took 3 hours to kill it. Then we rolled it off a 20 foot cliff. I drove on it with my old CJ-7 then we drug it upside down to the road and then scrapped it. Here is the link.

I think you have covered all the bases..............But I've been running 98oct Fuel, a 92deg/c thermostat(so it gets hot & stays hot which stops the computer gong back to cold start fuel map- below 88deg/c) & I'm also run a 3" FRAM AIR HOG pod filter in a Cold Air Box. I may have a big advantage as i'm running 31" Bighorns @40psi/Stock 3.54 ratio's on my 01 Classic 4lit-L6 & it returns on average 9.8lit per 100klms(Hwy) / 12.3lit per 100klms(City)Sorry I haven't converted it to US/MPG. I did stuff up my eco by going to a 2 1/2" Cat-back exhaust with straight thru muffler & this reduced the back pressure so the fuel consumption increased by 3lit/100kms so i then changed back to a loop flow 14"long by 2 1/2" bore muffler.......Now for some reason the rest of my mates with XJ's & TJ's can't get anywhere near my economy because they running 32's, 33's or 35's with various different ratio's or they have a lot larger right feet.
