I don't have any UOA's that I've done but I've been running it in my Cobra for 3 years and in my 4Runner for a year and I've been very pleased - quiet and smooth engine, no makeup oil added, no leaks, etc. Regarding the PQIA link I mentioned, only Pennzoil Ultra and Quaker State Ultimate have a lower NOACK % than PP which is pretty impressive considering there are some big name oils in there like Royal Purple, Lucas, Mobil 1 and Castrol Edge.
If you want UOA's for it there are plenty to be found online that look good -

I've managed to secure 25 quarts of Pennzoil Ultra from clearance sales at Walmart and the next few oil changes will be with that oil. I doubt I will notice a difference but I guess I'll see.
I hope you know I'm not trying to give you a hard time. Its just that we run motor oil in harsher environments than most cars. And at some point, the UOAs do become a measuring tool to evaluate which oil cuts the mustard and which doesn't.
