i haven't done it myself but from what i understand, you would need to use the premium fuel settings and you would have to use premium fuel in your jeep to get it.

I'm using the Economy Fuel Setting, and I'm getting 17/18 in the city and 20-22 on the highway.

I used the Premium Fuel Setting before and was getting about 15 in the city and 17 on the highway.
