What's the best oil for my Ford Focus engine?

I'm not sure what type of engine oil to use for my Ford Focus. I noticed there are different types available, such as synthetic, conventional, and high mileage. Can someone recommend the best type of oil for my car?

Based on Ford's recommendations, the best oil for your Ford Focus engine would be synthetic oil. It offers better lubrication and protection for your engine.

As a Ford technician, I prefer using high mileage oil for Ford Focus engines. It's specifically designed for older engines and helps reduce oil consumption.
