What is the best way to maintain your Ford S-Max's engine?

I recently bought a Ford S-Max and I want to know the best ways to keep its engine in top condition. Is it important to have regular oil changes and tune-ups? What other maintenance should I consider?

Regular oil changes and tune-ups are essential for maintaining your Ford S-Max's engine.

In addition to regular maintenance, it's also important to check your engine's fluids and replace any worn out components.

Don't neglect the air filter - a clogged air filter can lead to decreased engine performance and fuel efficiency.
