You might as well as which god is the best god. I personally do not add oil additives and have not for over 20 years. I've had no oil related engine failures (actually no engine failures of any sort) in that time. I could not tell you how may miles that covers between my and my wife's cars, but all were replaced with over 150K on them (some close to 200k).
I also don't recall ever seeing an "I changed my oil regularly with appropriate quality oil and my engine still suffered an oil-related failure" post of any message board I've ever visited. Do whatever you want with this info
For what it's worth, this is what BMW says in the manual:
