How do I make my 03 TJ more gas efficient?

Gas in CT is expensive and I drive a lot!

I bought my '03 TJ with 11,000 miles on it three years ago.
I know have 75,000 miles!
I love my Wrangler and drive it everywhere but it's killing me in the wallet.
Any suggestions?
Also when should I get a full tune-up?
Was it supposed to be @75,000 miles?
and what would that entail

There should be a regular maintence schedule in the back of your Owners Manual. I know you have one at 80,000 off the top of my head.

Other then that, theres not much you can do. TJ's have the aerodynamics of a brick.

Best way to keep gas mileage is to keep it as close to stock form as possible. Lifts don't affect gas mileage, but larger tires will. As well as adding hefty bumper/winch combo's.

I guess thats what you get when you leave your soft top in the ghetto.

Ebay probably would be your best bet. The dealership can get you one but it'd be cheaper else where.

I'm pretty sure removing those bumper end caps make it more fuel efficient as well.

change your oil, keep air in your tires and keep your rpms under 2. Other than that you are S.O.L I feel your pain though I put 7k on my jeep in the 2 1/2 months of having it. So when I drive it I gotta kick it in the ***, kinda like sealing the deal after getting caught messin around with the ugly fat girl in the bar. Your friends are gonna make fun of you anyway

Slow down, that is all you can do to help your MPG. Make sure you stay up to date with your maintenance schedule too (i.e. sparkplugs, air filter, etc. etc.). I'm sure the schedule is online if you Google search it - or even on this forum.

If you get bigger tires, re-gear accordingly also.

my only advice for improving your gas milage to help save money would be to sell it, or put it aside and pick up a toyota camrey

Pretend there is an egg on your gas pedal, and drive like you're scared to break it.

Then keep it tuned up well and your tires inflated to the proper PSI.

That's about all you can really do, and it's still not going to get great mileage.

If you're worried about gas mileage, maybe you should be driving something else.

.

One relatively inexpensive thing you can do is add a can of 44K to the gas the next time you fill up (important: don't just add to a partially full tank and take off). This stuff cleans the fuel system pretty good. That'll allow you to ease up on the gas pedal while still being able to keep up with traffic. Unfortunately, the stuff is only available at dealerships and costs about $25 a car. But it's be best out there. Made by BMG who has other treatment system but this is about the only one that is one-step.

The RPMs below 2K is, as mentioned above, a tremendous gas saver. Remember, it's a Jeep not a Porsche.

Keep your tires inflated to the highest they are rated for (if well below that now, be careful until you are used to the difference in handling).

You may be running a rich mix as well. If you have a local dealer or shop that can test your exhaust emission versus what it should be, you might discover if running rich is the case. That could be caused by bad sensors or chip being screwed up.

It's a quest saving gas; not a destination.
