It will depend on how you drive like no hard accelerations and staying within the speed limit helps. Also the type of terrain you drive on. Hills and mountains will reduce the gas mileage you get big time. I had a 91 4x4 and now have a 04 4x4 and both average about 15 mpg combined city/hwy. Hwy only on mostly flat roads 17ish pushing 5-10 mph over the limit. Make sure your tires are not under inflated. I'm assuming you don't have a camper on it.
