How do I properly maintain the engine of my Ford S-Max?

I recently purchased a Ford S-Max and I want to make sure I take proper care of the engine. What steps should I take to keep my engine running smoothly and efficiently?

First, make sure you regularly change your oil and oil filter according to the manufacturer's guidelines. This will help keep your engine clean and properly lubricated.

Another important step is to check your engine's coolant levels and regularly replace the coolant when needed. This will prevent your engine from overheating and potentially causing damage.

It's also important to keep an eye on your spark plugs and replace them when necessary. This will help ensure your engine is running at its best.
