I take advantage of the free oil changes, after that I do my own. I buy a Mopar filter and wherever I can find the oil the cheapest I save my receipts, so that if the issue ever comes up, I can show receipts for filter and oil at regular intervals.
When I had a JL, it made a huge difference on the highway. I now have the JT, but I’ve read conflicting arguments saying if you change the oem steering stabilizer for an aftermarket, it gives the dealer the opportunity to say, you altered the stock configuration and voided your warranty.??
