I was actually referring to the previous UOA which you did take from the pan, I thought maybe some RT6 or something got mixed in, thus thickening the sample.

It could also be that they mixed up your sample with someone else's. Gathermethewool's UOA showed 11% shear, which while not great, is much more believable.

The discussion over at BITOG is interesting. Like I said before, this is the oil Amsoil would recommend for a VW 2.0t (GTI/TT/A4), and those things are murder on oil, especially the gen 1 engines (pre-TFSI) they make a WRX look positively kind to oil. So the idea that this low-SAPS oil would obviously not be up to the task of a WRX seems strange to me.

I found this discussion at BITOG (link) which seems to indicate that the Euro manufacturers screwed up yet again when translating requirements to the North American market. Apparently the low-SAPS oils aren't up to long drain intervals in gasoline cars due to ethanol and sulfur content in North American fuel, though they do fine in diesels.
I will follow up with Blackstone and ask them to confirm.
