It looks like my Carrera T is holding up well to track use. I've switched oils a few times (all Porsche A40 approved):
1) dealer-fill Mobil 1 0W40
2) self-fill Motul X-Cess 8100 5W40
3) self-fill Mobil 1 5W50
There are few miles on the engine, and my OCIs have been short due to track use, but it seems that Mobil 1 5W50 is working well. It's MUCH cheaper than Motul X-Cell 8100 5W50 and I needn't worry about steering out of range like Mobil 1 0W40.
Note:

Note:
- The latest sample is missing a value for aluminum. I've asked Blackstone why that is.
- The jump in lead coincided with filling up with gas at the track. The "unleaded" gas likely wasn't completely unleaded.
