How to properly maintain my Ford S-Max's engine?

I have a Ford S-Max and I've noticed it's been running a little rough lately. What steps can I take to properly maintain my engine and keep it in top condition?

Regularly changing your oil and air filters can significantly improve the performance of your Ford S-Max's engine. Also, make sure to check your spark plugs and ignition coils for any signs of wear and replace them if necessary.

Don't forget to also check and top off your engine coolant and transmission fluid. Keeping these fluids at proper levels can prevent overheating and component damage.

If you notice any strange noises or vibrations coming from your engine, be sure to have it checked by a certified mechanic. Ignoring these warning signs can lead to more costly repairs down the road.
