What is the recommended oil type for a Ford Focus?

I just bought a used Ford Focus and I'm not sure what type of oil to use. I've heard conflicting information from different sources. Can someone recommend the best oil type and brand to use for this car model?

I recommend using a fully synthetic oil for your Ford Focus. It provides better performance and engine protection. As for brand, I've had good experiences with Mobil 1 and Castrol Edge.

I have a Ford Focus and I always use conventional oil. In my opinion, it works just as well and is more affordable. I've been using Valvoline for years and haven't had any issues.

I've heard that using a blend of synthetic and conventional oil can be a good compromise. It may provide better protection than conventional oil but is still more affordable than full synthetic. I've had good results with Pennzoil Platinum.
