How to Maintain the Engine of Your BMW M1?

I just bought a BMW M1 and I want to make sure I am taking good care of the engine. What are some essential maintenance tips that I need to know?

The engine oil and filter should be changed every 7,500 miles or every year, whichever comes first. This will keep your engine running smoothly and reduce wear and tear.

Regularly check and top-up your engine coolant to prevent overheating. This should be done at least twice a year.

Inspect and replace the drive belt every 30,000 miles or so to avoid potential engine failure.
