What's the best oil to use for a Ford Focus engine?

I recently bought a Ford Focus and I'm not sure what type of oil to use for the engine. I've heard that different types of oils can affect engine performance and longevity. Can someone recommend the best oil for a Ford Focus?

As a mechanic, I recommend using synthetic oil for your Ford Focus engine. It provides better protection and lasts longer than conventional oil. Plus, it's what Ford recommends for their vehicles.

I've been using conventional oil in my Ford Focus for years and I haven't had any issues. Just make sure to change it regularly according to the recommended schedule.
