Check the "oil nerd" thread -- I seem to recall there being some UOA's on the Quaker State synthetic...
I will say this much: After pouring over numerous UOA's for the 370 and 350 motors, and also sending my own samples to Blackstone for analysis, across users' UOA's Redline has performed really, really well, and surprisingly, showed better wear characteristics than typical favorites like Mobil 1.
So, FWIW, I've been sticking to Redline.
