I've got the PUP 0w20 in my 18 JL right now. I'm at about 3500 miles, so it will be a little while, but when I change it, I'll do a UOA and post it. It is a 6 speed and is a hoot to drive, so I frequently run it in a spirited way and it sees rpms right up to redline quite a bit. It'll be fun to see how it does, but I'm confident it will show well. I just don't know what it really has that "regular" Platinum doesn't, other than a higher flash point.
