How do I properly maintain the engine in my BMW M5?

I recently purchased a used BMW M5 and want to make sure I am properly maintaining the engine. What steps should I take to ensure the engine lasts for as long as possible?

Regularly change the engine oil and filter, according to the manufacturer's recommended schedule. This will help keep the engine running smoothly and efficiently.

Make sure to use high-quality synthetic oil, as recommended by BMW. This will provide better protection for your engine and help it last longer.

Don't neglect regular maintenance, such as spark plug and air filter replacements. These small tasks can make a big difference in the long run.
