How to properly maintain your Ford Mondeo engine?

I recently purchased a used Ford Mondeo and I want to make sure I properly maintain the engine to ensure its longevity. Can anyone provide tips or advice on how to do so?

Regularly change the engine oil and filter every 5,000-7,000 miles to keep the engine running smoothly.

Keep an eye on the engine coolant levels and make sure to replace it as needed to prevent overheating.

Clean and inspect the spark plugs every 30,000 miles to ensure proper ignition.
