I agree. It's a few oil changes at $25 each and it takes me about 20 min to do since I can just crawl under the jeep without any jacks. Already done two and I'm now at 6k miles switching to 5-6k intervals. Also did my rear diff fluid which took another 15 min.The dork at my local dealer is not touching my Jeep. I will pass on the free oil changes, I always have done my own it don't mess with the warranty just keep your receipts.
I feel like the last oil change and rear diff fluid change to 75-140 has actually increased my mileage a little. Stock diff fluid was black and lots of metal shavings on the drain plug.
