The best way to increase mileage is to change your driving habits. Be light on the gas. The best I have gotten in my 03 4.0 5 speed 4wd with 31s, Magnaflow catback exhaust adn cranked bars is 19.5MPG mostly highway.

May need a tune up. That's some pretty crappy mileage. I got about 15 or a little less when I drove in stop in go traffic in a busy city all the time. With my exhaust, intake, and tuner I get about 18.5 in the summer and about 17.5 in the winter with mixed driving.

Just filled up right before I got here to work and this last round was 19.13mpg all city driving. I've got a manual 4x4 with 31's. That 12mpg you got just doesn't sound right at all. Like Mike said you may need a tune up. Try running some lucas cleaner through it.

K&N will give you like 1MPG difference but since it sucks in hot air you wont get any power or little from it. Opening the exhaust will help a bit. I still think you are on the gas too hard. If you can hear your intake growling then you are using to much throttle.

I have the 4.0 sohc auto with 4x4 and 4.10's and I get pretty crappy mileage. 14 sometimes 15 city and if i stay under 65 mph on the highway I can almost get 20. It was just recently tuned up, and I use synthetic oil and run fuel injector cleaner every oil change. Also my tires are always properly aired and i never go above 2,500 rms. Also it is stock with the exception of 2" lift. I am thinking of doing some seafoam or the motorcraft equivalent in the spring.
Any other ideas anyone?

its been cold and the intake growls alittle longer when i first start it up in the morning. i dont really let it warm up enough so maybe that has something to do with it. i was getting better gas mileage in warmer weather so it may just have something to do with the cold engine

Actually you lose mileage by letting it warm up. You get 0.0MPG since you are burning gas but not moving. I let it idle for about 2-5 minutes then I take off and drive it easy until it warms up. Then I'll drive a bit harder but still take it easy. Try using less throttle and letting off the gas earlier. What hurts the most is getting back up to speed. Also coast down hills.

i'll do that half my drive to school is down hill and i usually just take my foot off the gas at the top and let gravity take over.

Short trips will hurt mileage. But again with that many miles do some maintenance. Tranny flush, plugs and wires and maybe seafoam or that Motorcaft stuff.
