Question Mileage for 2012 JKU?

Just curious what mileage everyone is getting on their 2012 JKU's? I'm getting 13-14 in the city according to the mileage calculator on the dash. I'm going to calculate it myself in the next tank. I've got 2800 miles on the engine. Mileage seems low to me.(

There are lots of posts about this if you do a search. I am actually very happy with the mileage I am getting on my 2012 JKU. I drive about 50 miles each day in a mix of city/2-lane highway and when I am light on the pedal I average just about 19-20 mpg (calculated). Now when I am heavy on the pedal or stuck in traffic it plummets down to 14-15 mpg.

Still what do you expect from a brick on wheels?

At 9000ish miles I am averaging 18.8 mpg with a mixed 40/60 city/highway 50 mile a day commute.

A recent all highway (or at least 90%) tank I averaged 22.2. That being said I had about 3/4 of a tank on mixed gravel and muddy dirt roads a few weeks ago and averaged 14.8.

I hand calculate for all of my fill ups, but the EVIC is usually no more then +/- .1-2 assuming I reset it after every fill up.

I drive a '12 Unlimited with 3.73 gears and an automatic. Stock Sahara tires and rims.

2012 JKUR, 6spd, 2" spacer lift, 33" duratracs, 4:10, 6000 miles - worst 14.1 best 18.9

around town 15.5 to 17
highway under 67 17.5 to 19
highway over 67 drops like a rock so I try to keep it under 67mph
The 14.1 was pulling a utility trailer

I had hoped for better but given the vehicle, mods, and the figures on the sticker probably right about where it should be.

Well mine has been at Don A Vee Jeep since Friday. It wouldn't start and they believe its computer related. Hopefully, it's a computer glich. Everyone's getting better mileage than me!
