I'll say it since no has yet. 
Its a Jeep. It's not going to get great fuel mileage.
I would not jump to trust the computer for the mpg, if that is what you are using for your figures. It is better to compute it yourself by miles / gallons used and do it a couple of times. It will be the average of all your driving, and that to me is more realistic.
I do get better mileage from high octane fuel, but not enough to warrant the price differences.
The best thing that I did was getting the Superchips flasher. I see about a 2 mpg increase with it, and some increase in performance. Very happy with it.

18-19 is not bad, search for MPG threads. 11-12 sounds a bit low. The flashpaq will give you the biggest bang for your
Buck, but the gears will make your Jeep more driveable.
