2006 Jeep Grand Cherokee Overland Gas Mileage?

I'm looking to trade up to a 2006 JGC Overland with the 5.7 L HEMI. Does anyone know what the actual gas mileage is? I've been researching it and have seen anything from 12-25 so i dont know what to believe. Also, i've seen that you can use either 87 or 89 octane gas? Is this correct? Please Help with any info you might have...
