So much for the 16/22 figures Jeep advertises... I'd kill to get 16 mpg in the city!
that sounds right for my situation too

except that I probably drive too fast on the highway and get 18.

17.11, 17.21, 14.23 - I was using 4wd quite a bit

130 miles on the tank....I'm about to hit the mark for 1/8 left. I think I'm doing quite well...

On a side note, I'm at about 32k miles so I know I need plugs. I have a feeling that's killing my mileage...

I guess that could be my issue a but too. Just hit 40k on stock plugs.

You'll be amazed how much better your KK will run if you change out the plugs..

Now is that just the normal lifespan of plugs on the Libby or is that just the stock plugs?

The Liberty uses copper plugs. So they need to be changed every 30k miles. Don't use a different plug to not change as frequent cause that could lead to issues.

Just filled up, 8.6mpg. And yes, I did correct for the larger tires lol. We had a snow storm this week, and I know plugs need changing. I barely used 4wd. I stay in rwd unless I'm starting on a hill or need to take of quickly(which only happened 2 or 3 times).

Change those plugs!
I usually rant how easy it is to change plugs, but apparently on the "newer" KK's it's not as easy as the 2008-2010.
Only place I could find the NGK plugs was at the dealer FYI.

Have to report Tom was getting 23.5 on a straight flat county road going 50 Man, I need to regear. I get about 15-17 mpg under those conditions. Tom is rocking 265/75/16 Duratracs with 4.10's, whereas I have 245/75/16 Duratracs with 3.73's. I usually press the Tow/Haul button to lock out overdrive at those speeds because it can't stay in 4th gear if there is any kind of topography. I could go to 4.10's or even 4.56's with the KK. 4.56's would probably make it feel like a Hemi, but mileage would probably suffer. I don't know if anyone with a KK has gone to 4.56 gears yet.

Did you meet John(jeepin_it_reel) when you were on the island? He has 4.56 gears, and he's spinning 265/75-16s.

And Gage, yeah I know I have to. It's just really cold lately and I don't wanna leave the house unless I have to lol

Let me ask this, does the KJ get better mileage normally due to its slightly more aerodynamic body compared to the Refrigerator box we drive?

From what I've seen on the forums, yes. Usually it's about 1mpg better or so. It's not much. I'd say for the most part we're all even. I've seen some KJs get a lot worse mileage compared to a KK.
