Which oil is best for a Ford Mondeo?

I just purchased a used Ford Mondeo and I'm wondering what type of oil I should use for optimal engine performance. I've heard conflicting opinions from friends and mechanics. Can anyone provide some insight?

For your Ford Mondeo, it is recommended to use synthetic oil to ensure the best performance and protection for your engine.

I've been using conventional oil in my Ford Mondeo for years and have had no issues. It really comes down to personal preference.
