Not impressed with VOA/UOAs I've seen that oil (Pennz Ultra 0w40), certainly not to the point of calling it the 'god' (or even minor deity) of anything. Its possible its got great anti-wear in an additive pack that doesn't show up on simple analyses, but my guess is that its really just a 40-weight version of their 20- and 30-weight A1/B1 oils.
Pennzoil Ultra 0w-40 has a lot of moly (275 ppm), possibly even the trimer moly from Infineum, in a large enough amount it starts to have AW benefits on top of the usual FM benefits. (Chrysler engineers were touting extra moly in it for their SRT engines a while back.) Also, Pennz has an ad campaign with it being used in racing BMW's. http://www.bobistheoilguy.com/forums/ubbthreads.php/topics/3922550/Re:_BMW_Motorsports_uses_0w-40
Therefore, use it! That oil is no slouch.
Below is a link to a quick VO analysis of PU SRT 0w40. I wouldn't call it a "bad" oil, but its not on a par with a Euro-spec A3/B3 like M1 0w40, or better yet a racing oil, "street/strip" oil, or HDEO. PU 0w40 SRT is very targeted at a (healthy) Chrysler Hemi v8 (392 or Hellcat) with rollerized everything that's pretty easy on oil. It wouldn't even exist if SOPUS hadn't gotten the contract to provide oils to FCA, they'd just have their Euro 5w40 and their A1/B1 20-and 30-weights for the US market and Dexos applications. If you are addressing an apparent wear problem in a different engine, I simply think you should take a bigger swing at it than this oil provides by going for an oil with more ZDDP, that is if you can't find and mechanically fix whatever is wrong.
