What is the best oil to use in a Ford Focus?

I recently purchased a used Ford Focus and I'm not sure what type of oil to use. Should I use synthetic or conventional oil? Is there a specific brand that works better for Ford cars?

I would recommend using synthetic oil for your Ford Focus. It provides better performance and protection for your engine compared to conventional oil. As for a specific brand, I have had good experiences with Mobil 1 or Castrol Edge.

I've been a Ford mechanic for over 10 years and I always recommend using Motorcraft synthetic blend oil for Ford cars. It's specifically designed for Ford engines and provides great protection.

I've always used conventional oil in my Ford Focus and haven't had any issues. It's cheaper and gets the job done, but I would recommend changing it more frequently.
