4" lift and MPG report
I keep track of every tank and thought some folks might be interested in the effect of the lift.
Here is the trend for the past couple months fill ups
15.51 MPG (did some trail riding)
17.48 MPG
19.44 MPG
15.54 MPG (more trails)
16.97 MPG
17.81 MPG
18.27 MPG
16.86 MPG (4" Rancho Sport lift installed during this tank)
17.73 MPG
14.73 MPG (trip across State must have been headwind)
18.02 MPG
14.67 MPG (nothing note worthy )
16.58 MPG
Rolling average before lift +/- 17.28 MPG
Rolling Average after lift +/- 16.35 MPG
Still on the stock 255/75-17 and 3.73 auto so the only variable was the lift install. I also kept the air dam in place... for now.
Just pulled the trigger on 35" KM2's. I'll have them on in the next couple days so I'll report back in a month or so with the... ahhh... bad news...

I swear JK mileage is all over the place. I had a buddy that had a 2007 2 door auto that was bone stock. He got 13 - 14 mpg. Then he traded it in on a 2009 unlimited auto and he gets 18 mpg.
I have a 2008 rubicon 6 speed with a 3" lift, 35" KM2s and 4.88 gears. I got 18.5 MPG on my last tank. That was all city driving. Although I do usually drive early in the morning so traffic was light.

My 2009 Unlimited stock gets 18-20 on the highway. I figured the average on a recent roadtrip to Utah and on the way there was consistently getting around 19 MPG. The way back we fought a nasty headwind so it was down around 16.

high mpg
I was supprised with my jk i get 19 in town and 23-24 on the highway thats one of the reasons im scared of lift and bigger tires. i have the tf leveling kit and that made no difference on the mpg.

How much off road improvement?
With the new 35's. Was it large or does it just look better? And how about the power and throttle response? Please keep updating the MPG rates too. Good thread. What 35's did you get?

It has a lot to do with the terrain you drive. I live in southern central Indiana (HILLS) and fuel mileage is on the low side. But when I am up north mileage goes up Flatter ground. My best 17-18, on average 16+or- and I drive easy.
