What is the most efficient way to maintain a Ford Focus engine?

I just bought a used Ford Focus and I want to know how to keep its engine running smoothly. Which maintenance tasks should I prioritize and how often should I perform them?

Regular oil changes and tune ups are key to keeping your Ford Focus engine running efficiently. Also make sure to check and replace air filters as needed.

Keeping up with routine maintenance such as checking and replacing spark plugs and coolant can prevent unexpected breakdowns and save you money in the long run.

I recommend following the manufacturer's recommended maintenance schedule for your Ford Focus. This will ensure that all necessary tasks are completed at the appropriate intervals.
