Based on my research the go-to do-it-all brake fluid is Castrol SRF. It's got a high wet and dry boiling point, plus 18 month service life. From what I've seen on the BMW side, guys usually do a full bleed once at start of season for HPDE.
It has access to everything. It creates the oil life percentage by driving habits, coolant temp, and throttle % usage. Honda is the largest engine manufacturer in the world and has been using the system since ~ 2006.
Asking for real data and not anedotal information does not make someone a snowflake. Getting annoyed that people don't accept your "confirmed" OCI without any real proof makes someone else a snowflake......
I find when the engine is hot, the 0W20 oil immediately flows down the stupid orange dipstick.
What I do is leave the engine cold overnight. Start the car for 30 seconds. Turn it off, and wait about 3 minutes before checking.
Oil level difference after start versus before start is about halfway...
