Oil weight for track/street car question

Awesome. Honestly, I didn't expect that non-existent difference.
Apparently that N52 (?) loves extended periods at high revs.
That doesn't necessarily apply to any kind of ICE though.
Yeah, N52. But, like any BMW, works best when pushed. I do run 335 oil cooler.
I have seen numerous UOA that doesn’t justify early change. Now, running alcohol etc. is different thing, and, sure each engine is different, so without UOA to compare to regular driving or other UOA’s is just speculation when oil should be changed.
