What maintenance is needed for a BMW M6 engine?

I just purchased a BMW M6 and want to make sure I am properly maintaining the engine. What specific maintenance tasks should I be performing and how often?

Regular oil changes are essential for the performance and longevity of your BMW M6 engine. They should be done at least every 7,500 miles or once a year, whichever comes first.

In addition to oil changes, it is important to regularly check and replace air filters, spark plugs, and other engine components as recommended by the manufacturer.

For optimal performance, consider using premium gasoline and using a fuel additive every 5,000 miles.
