I just changed my oil right at 22,000 miles on the JLUR. I had Pennzoil Ultra Platinum in it this run, and it did really well. The engine continues to improve as it is now fully broken-in. Now, I'm not talking about the original sub 1k mile break in where the rings seat, but rather where the engine settles in and starts to show very little wear. Most of my vehicles have seen this around 20k miles, so this looks to continue the trend, but I actually expect to see further improvement still.
Anyway, I ran a very expensive and hard to find Pennzoil Ultra Platinum in 0w20. Some think this oil is the same as Platinum, but Pennzoil reps insist it is better, although they won't say how. It does vary, but only slightly slightly on their product data sheet, showing a very slightly higher flash point and same pour point. It also is slightly thicker at 212 degrees (full operating temp), although still in the 20 weight grade, and also at 104 degrees (cold), which is still in the 0 weight grade at that temp. It is advertised to keep pistons "65% cleaner" while Platinum states "50% cleaner." It also is listed by Pennzoil as being for extreme performance, whatever that means. They don't really define it, but they do state that it is for Dodge SRT performance engines. I believe Ultra Platinum is the factory fill in the Hellcat and Demon engines, so maybe it is engineered for more high rpm high heat applications. Who knows? I do know it performed very well in my 3.6 and it could have gone much longer than 5,000 miles, as would any oil I've run so far. Of note is Pennzoil's 15 year, 500,000 mile warranty on Ultra Platinum vs. 10 years and 300,000 on Platinum.
I did add about one cup of oil at about 4k miles. The dipstick showed a very slight drop in oil level. I haven't had to do that before, but the amount was so small, it could have been a variance in my checking methodology. I try to do it by the book, with engine at full operating temp and then shut off for 5 minutes before checking, but I might have been off a little at that point. The oil I added was Pennzoil Platinum 0w20, as I had no Ultra Platinum in reserve. I didn't want to pay 20 bucks for a quart I didn't think I'd use. I would bet it didn't impact any of the data even in the slightest.
I've gone back to Mobil 1 AP 0w20 for the current run. It will likely be the most common I run, but I will try others from time to time. I have a stash of Chevron Havoline Pro DS full synthetic 0w20 that I might run next summer, if I'm in the mood to try it out. I do know that this report may make me come back to Ultra Platinum at some point, too.
The good news is that the 3.6 will run very well on any good quality 0w20 and should last a long, long time.
Every other oil change I've done on the JLUR is on this sheet, so enjoy!

I'm always open to trying something better, though, if it is out there.
