This is neat- another 4.0L UOA the same week as mine:

Comparing the two, your engine has about 29,000 fewer miles than mine, and your oil has 2900 fewer miles than mine (cue eerie music).
Your Mobil-1 obviously has more Moly (for those who like Moly
and less ZDDP than my RTS (older SL rated batch). Other than that, the numbers track OK. You're at 15 ppm FE and I'm at 19, which isn't as big a spread as I'd expect with the difference in mileage on the oil, but that might be the thinner oil or even the fact that it has less ZDDP. Or it might stabilize and turn out the same as mine if you ran it out another 3000 miles, hard to say.
Lead, copper, and nickel- same story. Close to my numbers but on fewer miles but that's nothing conclusive.
Its interesting that Blackstone's "Universal averages" column on yours is allegedly for 2000 miles, and mine is allegedly for 4500 miles and they're almost identical. Some might say TOO identical... Hmmm.
You didn't get a TBN... CHEAPSKATE!!!
I'll bet yours is a little lower judging by the lower calcium reading, but that's to be expected comparing an HDEO to a regular passcar oil.
I'll probably run another change of RTS (SM this time) over the summer and then I'll either try M1 0w30 AFE, or else an SL-rated 5w30 (maybe RP) and see how those pan out. I've always believed that Jeeps like slightly heavier oils, so I want to do a test with a lighter oil to confirm/deny the hypothesis.
