Is it better to use regular or synthetic oil in a BMW M9?

I recently purchased a BMW M9 and I am wondering what type of oil is best to use. I've heard mixed opinions on whether regular or synthetic oil is better for performance and engine longevity. Can you provide some insight and recommendations?

In my personal experience, I have found that using synthetic oil in my BMW M9 has provided better performance and improved engine longevity. Synthetic oil has a higher resistance to breakdown, resulting in less wear and tear on the engine.

While synthetic oil may be more expensive, it is specifically formulated for high-performance vehicles like the BMW M9. It provides better protection against extreme temperatures and high engine speeds. I highly recommend using it for optimal performance.

I have used regular oil in my BMW M9 for years and have never had any issues. As long as you follow recommended oil change intervals and use high-quality oil, regular oil should suffice.
