What is the best oil for a Ford Mondeo Ecoboost engine?

I recently purchased a Ford Mondeo with an Ecoboost engine and I want to make sure I am using the best oil for optimal performance and engine longevity. I've heard conflicting opinions, so I want to know from experienced Ford Mondeo owners, what is the best oil to use?

Based on my experience, I would recommend using a synthetic oil with a weight of 5W-30. This type of oil is specifically designed for Ecoboost engines and will provide better protection and performance.

I have been using conventional oil with a weight of 10W-30 and have had no issues with my Ecoboost engine. However, if you want the best oil for your car, go with a synthetic option as it will provide better protection.

I have been using a synthetic blend with a weight of 0W-20 and have noticed improved fuel efficiency and smoother engine performance. However, it may be more expensive than conventional oil. It ultimately depends on your budget and driving habits.
