Welcome to the world of Jeep'n, and the WF. Glad to have you on board. A lot of good people on this forum, with a lot of experience. The owners manual, if you got one, will be a good start on service intervals, types of fluids to use, etc. If you didn't get one, just call Chrysler/Daimler Corp. and tell them the year of your wrangler, and they will send you one cheaper than anyone else. I had to do that with ours too. Hope you enjoy your Jeep'n as much as the rest of us have, and will continue to do.
