Just gonna throw my two cents in here. I change my oil every 4,000 miles and use Valvoline fully sythetic oil. I don't worry about filters either. Whatever is cheap and looks good. On my old car I did the same and had that damn thing at 60,000 - 150,000 miles with no problems at all. So hopefully the Jeep will do the same (Started at 26,000).
