I've seen the tear down of a true synthetic 10W-30 just like above. The bearings look so good, we almost called BS that they had any use on them.
No, I'm not talking about the refined petroleum/PAO blend you were using in this picture.
This picture confirms exactly what Scott Whitehead commented about. 20 grade lubricants showing increased wear on the rod bearings.
IIRC, they were back spec'd to 5W-20 like all the other Ford Modular engines of the time.
I've been told that these bearings didn't look too bad. The coating rubs off with use and the shooting stars are a result of small particles getting caught in the "soft" layer a performace bearing has for that purpose. IE it's designed to catch those particles and embed them in the soft layer, the result is the shooting stars.
FWIW when I tore the stock motor down the bearings looked new. You can see the stock main bearings used in that build look very good too. Some rub marks but overall real good especially with the hp and shock loads it was subject to.
Anyhow those are the only motors I've done csi on. No hot spots on any bearings or journals. I've had the cam caps off a few times too during cam swaps. They look almost new and I haven't had a hot spot on any of the cams that came out.
Edit: That motor had mineral oil used for break in. Then it was RP 5w-20, RP 5w30, and I think M1 0w-30 and M1 5w30 were thrown in too.
Edit #2: Cam journals on stock head. IIRC this was with about 20k on them. The cam lobes just had wear marks, same as the followers in this pic. No measurable wear anywhere.
