How do I properly maintain the performance of the BMW M9's engine?

I just bought a new BMW M9 and I'm wondering what steps I can take to keep its engine running smoothly and at peak performance. What are the recommended maintenance tasks for the M9's engine?

As a fellow BMW M9 owner, I can offer some personal advice on maintaining the engine. First, make sure to follow the manufacturer's recommended service schedule and bring your vehicle in for regular check-ups. Additionally, be sure to use high-quality oil and change it at or before the recommended intervals. Keep an eye on your coolant and brake fluid levels, and replace them as needed. Finally, make sure to drive your M9 regularly, as prolonged periods of inactivity can cause issues with the engine.

As a BMW mechanic with years of experience working on the M9, I can share some professional tips on engine maintenance. Regular oil changes are crucial for prolonging the life of your engine, as well as keeping other components, such as the camshaft, in good condition. It's also important to check and replace your spark plugs and air filter at recommended intervals. And don't forget to keep an eye out for any warning signs, such as abnormal engine sounds or performance, and bring it in for a check-up if needed.
