So disappointed in my mpg even with low expectations!

Just notice you are running a Rubi, I'm sure that will make a little difference between yours and mine.

I have an auto, run my tires at 35 psi, and the drive was a mix of hills and flats. As for the procal, I used my gps and my speed is within 1mph so my computer is reading pretty close. Only thing it might do is fix my shift points for the larger tires. Oh, my rpm's were just above the Eco at like 2650ish I think.
At what speed and gear?
My '10 with 295/70-17 runs 2100 rpm's at 70mph.

Almost all of the MPG threads have mileage that varies widely. I traded in my truck for the jeep because of the increase in MPG. My expectations were around 15 MPG, compared to the 10 i was getting, and so far the panel indicator says between 19-21 MPG with mixed driving. Actual calculated mileage was about 18.5 for my first tank and I am completely stock. My guess is the guys on here will say check your tire pressure, slow down, and try a tuner. I would really like to know why it is so inconsistent even for stock jeeps. Gears maybe, I have 4.10's w/ a 6spd. What about you?
