How do I properly maintain my BMW M5's V8 engine?

I just bought a new BMW M5 with a V8 engine, and I want to make sure I maintain it properly to ensure its longevity. What maintenance tasks should I prioritize and how often should I perform them?

As a car enthusiast, I understand the importance of maintaining a BMW's V8 engine. First and foremost, make sure to regularly change the engine oil and filter every 5,000 to 7,500 miles to prevent sludge buildup and premature engine wear.

Don't forget to also check and replace the air filter every 20,000 miles or as needed. A clogged air filter can restrict air flow and harm engine performance.

In addition to regular oil and filter changes, make sure to also replace the spark plugs every 30,000 miles to maintain optimal engine performance.
