Why does my BMW M3 engine sometimes make a knocking sound?

I've noticed that my BMW M3's engine occasionally makes a knocking sound when I start it up or while I'm driving. What could be causing this and should I be concerned?

The knocking sound could indicate an issue with your engine oil. Make sure to check your oil regularly and change it according to your vehicle's maintenance schedule.
