It looks like after 6000 miles the oil sheared to around where the Mobil 1 and castrol edge euro start at around 12.5-12.8 cst.
Yes, the lower levels of moly may be due to, at least in Mobil's case, the use of tri-nuclear moly, which there was some infinium documentation on a while back. That's purely speculation on my part however.
And yes, the Euro 0w-40's tend to be a bit on the lower end of the grade, as the minimum HTHS is ~3.5cP and they usually are just a bit above that.
The SRT 0w-40 is 13.7cSt, whilst the Castrol Edge 0w-40, in its current incarnation is 13.5cSt ( current Castrol Edge PDS) ) so the AMSOIL product is a fair bit heavier than the spec product as well.
