What should I do to extend the lifespan of my Ford S-Max's engine?

I recently bought a Ford S-Max and I want to make sure its engine stays in good condition for as long as possible. What maintenance steps should I take?

Regularly change the oil and oil filter according to the manufacturer's recommended schedule.

Keep an eye on your coolant levels and make sure it's topped up when needed. Also, be sure to flush and replace the coolant every 2-3 years.
