2015 WRX Stage 2... oil recommendations?

T6 has ridiculously high NOACK. Don't think it's a great idea in a very hot turbo engine.

Castrol Edge 0w40 has moderate HTHS and a Ca level of around 1700 but decent NOACk. A little high Ca for a DIT.

Mobil 1 10w40 HM has a moderate NOACK, moderate HTHS, and low Ca. Probably the better choice but the Castrol is probably alright too.

There's a lot that doesn't show up in a VOA test. Castrol EDGE 0W-40 seems like a no brainer for your application in terms of performance and value.

I think you summed up fascination with T6 quite nicely.
