Seems very low for the way I'm driving. Granted, it's mostly around town, but still. Seems at the worst, I should be around 15+. My Range Rover averages higher than this!

Also, I've always used premium, but do you really need to? I have a loaded 4.8 (not sure if the sport package changes anything in the engine that may alter the need for premium gas).

Thanks -
