What is the best way to maintain the engine of a Ford Focus?

I recently purchased a Ford Focus and I want to make sure that I am taking proper care of the engine. Can you give me some tips on maintaining the engine to ensure its longevity? Any specific steps or products you recommend?

Regular oil changes and filter replacements are key to maintaining a healthy engine. I also recommend using high-quality, synthetic oil for better performance.

In addition to oil changes, make sure to also check and replace any worn out belts and hoses. These may seem like small things, but they can cause big problems if ignored.
