Drive slower, tune up the engine, and be a natzi about tire pressure. You can google how to hyper mile, but that is about it. You are driving a 4 wheel drive vehicle with 30 year old technology, with the arodynamics of a double wide. 13 isnt bad.

yeah, it really is all in the way you drive, just adding more stats: 2000 sport, 30's 5 speed, if i try i can get 21 mpg going 55 mph on the interstate. also if you wheel, say good bye to mpg. i got an average of 9 mpg my last tank due to having to much fun in the mud!

I have a 06 LJ Rubicon. In straight stock, w/auto, on the hiway with A/C going, we got 22-24 mpg driving 60 - 65 mph. Put 32 inch tires on, and that knocked the mpg back to around 20 mpg. I swiched to full synthetic in the engine, but haven't changed the diff's yet. With the weather getting colder, I can feel the "drag" in the diff's before the oil gets warmed up. I have a 45 mile round trip to work, and average about 18 mpg for work.

My question is to those who get 16-17..Other than plugs, wires, oil and filter..what else? Distributor cap and rotor? I've been meaning to change my diff fluid. What other suggestions?

As posted, I don't go above 63 max and drive like a grandma.

holy hell i wish i got 22 or even 16 heck even 14 mpg.......in the summer time Im able to get about 13-14 mpg and in the winter im getting 8-10 mpg but thats because I use auto start for about 3-5 min before my 5 min drive to work and again from work to home its great living so close to where I work, but it just kills gas your gas going on so many short trips a week

Direct your Air Intake towards your exhaust manifold to make it a warm air intake. You will lose power, but you will gain mpg's. The warmer the air the more prone for detonation and easier vaporization. your ecu will compensate for it by reading the IA sensor.

here it comes....

When I bought my '98 with 100k miles on it, I did everything you listed above, including the cap & rotor. I noticed the engine ran smoother. I also changed out the fluids (coolant + thermostat, diffs, transfer case, transmission). I recently got about 16 mpg going 68-70mph on a trip.

Our Jeeps get respectable mileage on the open road. It is the stop and go that kills us. I averaged a solid 20 on the interstate on a trip that had me stopping only for gas, and setting the cruise at 55 for hours on end uninterupted.
