xj = 21 mpg was my best, 235/65's, no lift bone stock 185k miles or so when I sold it.
xj with 3.5" lift and 31's, stock gearing, drove it like an asshole 15mpg on average.
TJ/yj = about 13-15 mixed bag of jeeps from stock to 35/36" tires

The one thing you'll find with a jeep is if you're cruising rural roads at 50-55mph you will get decent mileage, but as the wind resistance of a box and the rpm's creap up on the highway it will drop significantly.

My fullsize silverado's have always been around 15-18mpg, occasionally eek 20-22mpg out of a tank if I keep it around 65mph for an entire highway tank of fuel.

Mine used to be pretty good actually, about 14mpg. (304/T15/3.73s/35s)

I've had 3 TJs:

4.0 / AX15 / 3.73s / 31s + 3" lift = 15 city / 14 hwy
4.0 / AX15 / 3.73s / 33s + 4" lift = 15 city / 16 hwy (had header and CAI)
2.5 / 30RH / 3.73s / 31s + no lift = 15 city / 13 hwy

Wind resistance is the killer for these

Had 5 XJs, 3 stock, 2 lifted with 31s and 3" lift. all the stockers were like 16-22 city/hwy, the lifted ones were 15/20 both.

I had a stock 2008 JK up until last month and was averaging 18.065/mpg since I bought it new in the spring of '08.

I now have a 2014 JK Unlimited Rubicon and so far am averaging about the same but it's probably too early to really know how accurate that is.

95% of my miles are city driving.

My 89 YJ with 31's and 4.88's would get me 16-18 around town, and 19 hiway if I stayed at 60. It would actually hit 70, but mileage would drop almost 3 mpg at that speed.

I disagree with the negative comments on DD'ing a jeep, as long as you realize it's your DD and don't turn it into a 'wheeling project'. I enjoyed driving the YJ, just hated fixing broken stuff if I beat on it a little.

I had no problems DD'ing them, but the more modified they are, the worse it is, long term. First month is fun :)

The big issue is those vehicles are all getting old and wearing out. So as DD's for the money, they can end up needing a lot of maintenence to keep them going.

The newest TJ's are now 8 yrs old. The newest XJs are what, 12 yrs old. And the newest YJs are 18 yrs old. And all suffer terribly around here with rust. XJ's also are just a big rolling pile of electrical problems. And while it used to be, just a few years ago, that replacement motors and transmissions and such were a dime a dozen, they are starting to finally dry up, or all have 200k miles on them.

I agree with this, I commute 52 miles round trip with my 94 2.5 YJ almost every day (unless it's motorcycle weather). I like driving it, but it's all stock except some 30" tires. Plus, it saves a ton of miles on my truck :thumb: MPG is not great, the ride is about like a horse carriage, my feet get wet sometimes even with the hard top on, and working on it sucks because of it's age, but it's a jeep so you have to be ok with all of that! on second thought... get a little S-10 or something for commuting. ;)

My DD is a CJ5. Granted, I have less than 10 miles to drive to work, and during the summer I ride the motorcycle unless it is raining. Yes, there are times that I return from a weekend of playing and have to patch something until I can correctly fix it, but at the better part of 60 my hard wheeling days are over. A marine heater keeps it warm in the winter, XM radio with a nice enclosed system, and an upgrade to PS makes it an enjoyable ride.

The most I got out of my tj rubicon was 16 on the freeway. My v8 wj got as high as 20 on the freeway (hand calculated).

Even with a hard top i hated dd'ing the tj, it didn't get shit for mileage, you could hardly keep a conversation on the freeway, and absolutely no cargo space. With that said I loved the thing but all of the "jeep things" get old if you commute long distances daily.

The wj was my favorite dd of every vehicle I have owned.

My 4 cyl 5 speed tj on 33s gets about 21 city 14 highway. My 4.0 auto tj on 35s gets 15 avg.

Oh and btw, I love DDing my wranglers. I don't know why people are complaining about them, but every lifted TJ I have built drives and rides smooth. Yes they are noisy especially with my KM2s on 1 and swampers on the other, but my radio also gets pretty damn loud. Lol

It comes down to what you need it for and how much practicality you are willing to give up. There were times I really liked driving my TJ but I was putting 30k miles a year on it. Those miles often involved needing to cram a couple people and or some tools in it on a daily basis while getting the mileage of a truck. Sure it can be done but just about any other vehicle will be more practical than a CJ/YJ/TJ.
