I just bought a 2004 Ranger 4x4, 2 door supercab, 4.0L. with 45,000 miles on it. This is my first truck and I really love it. Its a perfect compromise of power and fuel economy plus I heard that if you treat rangers right they will last forever. Besides for the basic maintanence like oil and filter changes what else do you recommend to with a ranger to get it rolling like new?
