This thread hits on some of the stuff I read. Mainly, the PP 0w20 vs 5w20 NOACK values. The 0w20 actually has a lower NOACk than the 5w20, likely linked to better base stocks. Conversely, the PU 5w20 beats both.
The shear thing I read seems to mainly apply to w30 vs w20 oils as opposed to the low temp rating.

I believe Pennzoil Platinum and Ultra has been reformulated once or twice since then. See my reply above for the latest PP data points. You have to look for the "with PurePlus" data sheets for the latest.
At least I compared it to Mobil1 to keep this thread somewhat on-topic.
