Not a thread complaining about MPG, but somethings wrong

I know good gas milage and jeeps don't go together yeah i get it. HOWEVER, on my 2011 unlimited sport, I'm getting 12 around town. Now i am a conservative driver, the one who people usually pass when a light goes from red to green. This weekend i had 2 hour drive, all highway. I used speed control the whole way at 68, and reset the mpg before i got on the highway.

Are you ready....After 2 hours, my reading was 15.9 MPG!!!!! thats highway for 2 hours straight at 68! Does something seem wrong here? To me thats a red flag. I run 32's, nothing beefy, nothing in my car so theres no additional weight.

Can i hear your guys thoughts? It's really bugging me.

That's not very good mileage, but, without more info it's going to be hard for folks to help out....

Auto or Manual?

Axle ratio?

What tires?

Tire pressure?

Just a guess here but with the windy weather we've had and how UN aerodynamic the Wranglers are maybe going into the wind knocked down your mileage by a couple/few MPG ?? Also I always notice less MPG once the weather turns cold or the winter blended gas starts flowing.

I get anywhere from 13 - 17 on the hwy depending on wind and elevation and speed. I have a 2013 4 door Rubicon with an auto tranny and 4.10's. I get around 12-16 in town and have for the last 4 X 4 door Auto tranny Rubicons. It varies a large amount to elevation and wind but I lived in CO am now in NE and drive between the two states as well as up to WI.

Maybe so, that could be it. It is an Auto, as well as Chicago has been quite windy lately. I just didn't believe it was windy enough to get 15.9. I don't mind paying for gas, and i knew what i was getting myself into when i bought a jeep. I love it and will never be without one. But sometimes i just dream about the potential 2016 Diesel and can't help but smile.

I got 12 MPG in the wind driving to CO in Oct... Driving back I actually hit 18 and almost needed a picture. Wind pushing me into NE from CO hahaha. It makes a big difference.

I made a couple hour drive over to PA a couple weeks ago (pretty breezy) and heading there I was getting almost 22MPG (light foot on PA T-Pike, cruise set at 60-62mph). On the way home into the wind I was only getting 18-ish (also less T-pike driving) so I'd say a 3-4 MPG swing is very possible.
