So the question stands.
I'm not sure if there's actually a question, standing or otherwise. I saw AJ's post; he's said that before in other posts and I believe him. But let's put it in context: PTG is a privateer that used to run BMW's in North America under a contract with BMW. Very successful organization.
As a privateer, they're free to run any oil they want, so long as they get results. Presumably they ran Castrol Syntec for a reason and it worked for them.
Nonetheless, BMW Motorsport's spec sheet for the E46 M3 GTR with the 4 liter V8 (not the S65 derivative, the previous one that sold as a limited edition) specifically listed TWS as the engine oil. So does the spec sheet for the (factory-sealed) Formula BMW engine. The parts catalogs for BMW Motorsport race cars - M3 GT4, Z4 GTR, etc. - all list TWS as the engine oil, just like they list Castrol SRF as the brake fluid.
Doug Hillary has more recent experience of who ran what oil in which car at the 2010 24 Hr enduro at the Nurburgring, but TWS was a contender there, as I remember his report. Perhaps he'll come by this thread and add some color.
