Just enjoy your new ride and fill up when you need to. If you are concerned about gas mileage you just wasted 25K! Sorry, but Jeeps have NEVER gotten anything even respectable when it comes to gas mileage and they never will. They are built to run offroad and be used on the pavement as an expensive and uncomfortable form of transportation. I'm sure this comment will raise a few feathers but anyone who thinks otherwise has never driven a nice road vehicle.
