Sounds like you truly care about the maintenance of your Wrangler, yet don't want to get hosed at the shop for an oil change, paying top dollar for decent oil.
Let me suggest AmsOil. Truly one of the best synthetic oils you could possibly get, and through me, at possibly the lowest price as well.
What I do, and 95% of my customers do, is bring their OWN warranty and spec approved oil to THEIR dealership, or their favourite garage to have their oil changed.
This way, you aren't getting dirty, don't have to worry about property disposing of your used oil, and best of all, you save money on using a superior oil, and filter.
