Thats also part of the problem with these engines, too many people are 'nice' to them, leading to excessive blowbye. They're a [censored] race motor put into a streetcar. They need to be warmed up gently, and then drive the living [censored] out of them once oil temps are where they need to be (which is rather quick, oil temps warm up to 160+ in summertime in just a few miles.
The shop I work for has a customer who owns an E46 M3 GTS3 car that we put together last fall, fresh rod bearings on an otherwise stock, ~100k+ motor, and has won literally every race he's been in. It's been running Redline 40wt race oil, Blackstone analysis has been great.
