They probably use the cheapest Castrol 0w20 that they make which would be Magnatec. Which holds up in the Ford Ecoboost engines with great UOA results up to 7k generally. In many ways this oil is preferable to their higher priced oils like Edge and Edge EP Gold Bottle as far as UOA results go.
Long story short, it's probably a very good product with little to be concerned about.
