It's a lot about how you drive and your engine size.

I recently heard a person on NPR talking about driving to save gas. He suggested things like shifting before 2000rpm, rolling hills and rolling to red lights and stop signs also only carrying half a tank full when you can. I just got my 1995 Wrangler 4 cylinder and thought I'd give his advice a try. The first week was all in town and I got 18.2. On a recent trip to the foothills of NC (Saluda, Tryon) I checked my milage. It was about 70 percent interstate and the rest up and down mountain roads like White Oak Road in Columbus, NC and I got 20.1 mpg for the full tank. You can do better if you drive more efficiently and you might even enjoy the ride more.

Hey, I moved UP in MPG when I bought the Jeep. I averaged 13-15 in my old ('02) Silverado.

Why do Jeeps get bad mileage? Well let's see, these things come readily to mind....

High CG
Poor aerodynamics
Heavy
4WD power train
Big, heavy, fat tars (that's tires for y'all Yankee types)

Short answer is that almost everything that makes the Jeep a good offroad performer hurts gas mileage. Just the way it is.

All true
But at 4000 miles I put Mobil One oil in my new (2011) Rubicon and saw a nice improvement in MPG!

Also at 55 MPH on expressway I see 26 to 27 MPG

Let's see... they've got the aerodynamics of a cardboard box, they're heavy, they're geared kind of low, the 4.0L engine, while ironclad, isn't all that efficient, and maybe -- just maybe -- some of the people who drive them are, shall we say, "enthusiastic".

BTW, my 2000 TJ (4.0, auto trans, hard top, totally stock but with Kenda 30x9.5x15s at 27 psig) gets a whisker under 20 mpg running (nominally) 65 mph highway. Around town, with the front panel of the top off, it drops down to 16-17.

My gas mileage isn't actually much worse than my car. I get 20 - 22 in my '08 BMW 535i, and 16 - 18 in my '02 TJ.

And, the TJ is much more fun!!

I checked my mileage for the first time today and got 14.5 mpg. I was pretty proud of it, actually

I bought my '99 jeep wrangler sport new, I ordered it and took delivery in Oct of '98. Its an automatic (Wife didn't want to learn to drive a stick...)

When I had the stock 225/75-15's I would average 18 - 19 miles per gallon. I switched to 30/9.50-15's, my mileage dropped to a pretty consistent 16 mpg's... city driving, and I get that now.

I've never considered it a "brick". It is what it is. I knew what the estimated MPG's were before I ever bought it. I can't complain as it's met that target the past 13 years.

The only thing I can complain about is the amount of "rust" that has popped up on the frame and around my body mounts on the tub. The rust is coming from the inside (under the paint) out.

Yea, brick shape does it. I drive a focus for summer mileage, my YJ is for fun, and winter driving. I don't drive like a banshee in the Jeep, its not meant for that. Its meant to give a fun ride, and get you through hell and bring you home again.
Regular oil changes, good maintenance, gets your mileage acceptable and if you think about the longevity of these vehicles, its worth it.

Most 4wd vehicles get bad mileage... all those extra moving pieces going around, duh. And your windshield is close to 90 degrees to the hood, dont expect anything spectacular!

There is no excuse for the jeep, or any other vehicle to be getting poor fuel mileage, and to me, anything below 20 to 24 MPGs is poor. VW figured it out long ago. 42 to 50 MPGs, using diesel engines. The horsepower and torque ratings of gas engines are baselined at 3400 RPMs.. Diesel HP and torque ratings are all baselined at 1700 RPMs and as low as 1400 RPMs.. The math's very simple, since a diesel is at peak performance at around half the RPMs of gasoline engines, our CRD with 4:11s gets 27 mpg average, nearly double what the Rubi gets.. think what the CRD would get with 3:73s or even 3:27s.. Hmmmm.. When the motor goes in my Rubi, I'll be switching to diesel...

well the reason they get bad gas mileage is that jeep motors put that well needed low end torque to get you through that which is impossible for other land dwelers can't. It's a jeep we can go anywhere

True enough, but at 2,000 RPMs the 4.0 develops 170 ft lbs of torque... The VW tdi @ 2,000 RPMs is around 240 ft lbs of torque, and the cummins 4bt is over 300 ft lbs of torque at 1700 RPMs..

Agreed. I don't wanna be a ass or anything but I'm so sick of seeing these damn threads bitching about gas mileage. I get 11 MPG and never cried (out loud).

No one in my camp is bitching about poor fuel mileage .., the question was asked. I answered in so many words, it's because Americans are hooked on gassers, while the rest of the world understands the benefits of oil burners..
I'm very pleased to report that I get 16 or 17 MPGs .. When a new motor is necessary, I'll drop a diesel in it..

I believe it's not the jeeps fault for poor mileage as other factors are at play... Winter gas is a big one for Canadians who reside away from the US border. Environmental conditions is a another. Cold starts, idling to warm up. -30c weather on average where i live. The only thing im doing to make my jeep abit more efficient is swapping out the O2 sensors as they are are the point of needing to be changed. Another point i would like to contribute is the owners responsibility, maintenance is key as well. Regular oil changes, tire pressure at optimal levels, spark plugs as well. So for those out there who blame jeeps as being pigs on fuel, they are but they can be much worst if the owner doesn't do there part too.

Just my. 02 cents

My Jeep gains 20MPG when I take the top off, and another 10 when I take off the doors. Why? Becuase I stop giving a crap about MPG and am too busy having a damned good time just driving around.
