How to maintain the engine of a Ford S-Max car?

I recently purchased a Ford S-Max and I want to know how to properly maintain its engine to ensure its longevity. Can anyone provide some tips or advice?

Regularly change the oil and filter every 5,000 miles and monitor the oil levels. This will help keep the engine running smoothly and avoid any potential issues.

Make sure to clean the air filter every 15,000 miles to ensure proper air flow to the engine. This will help improve performance and can also increase fuel efficiency.

Check the spark plugs every 30,000 miles and replace them if necessary. This will help ensure proper ignition and prevent any engine misfires.

Regularly inspect and replace worn belts, such as the serpentine belt, as they play a crucial role in the engine's operation. This can prevent potential breakdowns or damage to other components.
