How often should I change my BMW M9's engine oil?

I recently purchased a BMW M9 and I am wondering how often I should change the engine oil for optimal performance. I have heard mixed opinions. What is your recommendation?

It is recommended to change your BMW M9's engine oil every 10,000 miles or once a year, whichever comes first. This will ensure your car's engine runs smoothly and prolong its lifespan.

If you frequently drive in harsh weather conditions or engage in high-performance driving, it is best to change your BMW M9's engine oil more frequently, around every 5,000 miles. This will prevent any potential damage to the engine.

It is also important to regularly check your oil level and quality, and top off or change it accordingly. This will help maintain your car's performance and prevent any unexpected problems.
