How to maintain the engine of a Ford S-Max for maximum performance?

I recently bought a used Ford S-Max and I want to make sure it remains in top condition. What are some key maintenance tasks for keeping the engine running smoothly and ensuring maximum performance?

Regular oil changes are crucial for keeping your engine running smoothly. Make sure to follow the manufacturer's recommended schedule.

In addition to oil changes, keeping your air filters clean and replacing them when necessary can greatly improve engine performance.

Don't overlook routine maintenance tasks like spark plug replacements and checking the belts and hoses. These small tasks can greatly impact the longevity of your engine.
