Any way to improve gas mileage?

I just got a 2006 Jeep Wrangler X and I feel like the gas needle is always dropping down. Is there any modifications I can install to help improve this?

If you have oversize tires you could regear. You could keep your foot out of the go pedal. Keep it under 3k when shifting. I've notice a improvement just keeping it under 3k.

The car came with after market tires (you can kind of see them in my profile picture; they're not much bigger). Does that make a significant difference? and what does keep it under 2k mean lol, I'm new at this, this is my first car

I've seen this dead horse so many times I just laugh. However, several have had minor success with replacing ALL O2 sensors and resetting the computer. At most 1-2 mpg. It may be worth a shot!

It basically means to stay under 2000 rpm while driving.

Buy a programmer. Set your computer up on economy and you will def see an improvement. You will loose some performance because it changes shift points but if getting an extra mile or 2 per gallon is important to you then it shouldn't matter how it performs. Or!!!! You could always get a PriASS

It's sad but true. I bought a jeep hoping to get better mpg than my truck. It worked but not by a lot. The jeep is just a toy for me but man it it more fun to drive.

You need to give up MPG for fun. If MPG is what you want sell it and get a car, wranglers are not cars. Do you think the driver of the Corvette says the same thing?

Are we helping you with a car or a Jeep? Big difference. Hah hah. Well the easiest thing is speed. NEVER go over 60-65 and it will get better mpg.

Drive like you have an egg between your foot and the pedal. Goal is to not break the egg.

Start measuring in smiles per gallon. You get more that way.

They sell hubs for it. They actually off of a ford ranger i believe. Being able to unlock your hubs so you dont have the drag of the front gears will improve mpg. I cant atest to how much, my uncle is doing this to my aunts tj..... ill try to remember to post it when he gets it all done.

From what I have seen, a half at best.

everything I've read says its 0.5mpg or less. the general consensus is the lockout hubs are not worth the cost if your solely looking for MPG increase.

It all comes down to having the proper gearing for the type of driving that you do and changing your driving habits. I was able to get 18-20 mpg out of mine with 3.73 gears and 33s but nearly all my commuting miles were highway miles which the 3.73 gears were very good for. I could cruise at 65 mph @ 2000 rpm. However if most of those miles were city I'd be better off with 4.56 gears. I also drive like an old man which helps too.

I pretty much gave up on the whole mpg game because I have a 90 mile commute to and from work so I bought a commuter car. The money I save in gas is enough to make up for the car payments and I get to save those miles for offroad from now on and occasional fun trips.

Get downsized and collect unemployment.

I have a daily driver, a handshaker cavalier 4 door with 200 thousand miles, that last fill up ( 3 quarters full because i never fill up for some reason) millage was 370. My wrangler, 3 quaters fill- 179 miles. Guess which one i actually daily drive. Not the cavalier haha. I have issues.

So glad i have this 1500 dodge 4door the company was nice enough to supply me with, along with the gas card. Mpg's on my wrangler dont mean squat to me . But if i didnt have this, im sure the cavalier would be in the drive way.

Those RPMs would not be appropriate for the TJ, they would lug the engine. <2000 rpms are only appropriate for lightweight sleek aerodynamic cars, the TJ needs higher rpms to propel its barn-door aerodynamics through the air and to turn its significantly heavier and harder to roll tires. Running RPMs that are too low on the TJ can actually harm the mpg by lugging the engine and keeping it out of its most efficient power band.

In fact, regearing the axles to raise engine rpms after installing bigger tires can actually improve the mpg since the engine is operating at a higher efficiency.
