All city with 5.13's, that sounds about right to me.... I think the OP is complaining that he's getting that even with highway driving mixed in and onlu 4.10's.

JFD140,
Aren't you the one that hydrolocked your engine?

I can only go about 55 max but hey i dont care. Going fast is overrated anyway
but on the interstate at 55 mph i get anywhere from 9-11 mpg depending on how the wind is treating me.

Oops...my bad, got the posts confused. That does seem a little low for 3.73's, but even at that, it really depends on how you drive in the city.
Some think that lower gearing will actually help. I'm going to 4.88's (6 spd Unlimited) just to get my top end back.

Free site for tracking your mileage and easy to use.

TrackYourGas.com

Looks like there are a few Jeep entries. 10 of those entries are Wranglers.

I get about 15-18mpg in the city and 17-20mpg on the highway, when I'm driving up the mountains I get about 13-15mpg.
4in lift
37in tires
Superchip seems to have helped a lot because I was getting 12-15 hwy before and I was running 33in tires before the chip, but I also changed my gear ratio to 4.10. Which works fine for me.

I have a 2010 Wrangler Unlimited 6 speed, 3.73 and about 1,100 miles.
So far I've typically averaged 18-19 MPG.
Highest average for whole tank of gas was 19+ something and lowest was 17.8
The low included some city driving and 4x4 on snowy roads.
My typical drive includes backroads at 55 mph mixed with suburb and I usually drive it like I'm being followed by the police.

08 JK Unlimited 6 speed, 5.13 and 35" tires. 30K miles. Mostly used in a 15 mile commute on a freeway at ~60mph using the cruise control (speedometer says - haven't re-calibrated it). Unfortunately, it sits at about 2800rpm. I regeared it for the top end power though, not milage.

I consistently get 12mpg. Almost to the tenth.
