Legion5 - You do realize that your argument is totally illogical right?
You state that the best way to break-in the engine is to run it hard.
You state that BMW tells you not to break it in hard to "minimize damage" and "reduce risk". Risk of what? You just said running it hard was the best way to get "extra reliability".
Also - various manufacturers do use additional additives in the factory oil. Subaru for one used a specific oil in my 04 STi. I dont know if BWM does or not, but I wouldn't assume anything.
