Ford explicitely says that you can use these motor oils:
Recommended 5W30 (Formula E Ford specification WSS-M2C912-A1) -> This oil has been superseeded by Formula F
Alternative (i.e. ok to use):
10W30 (class of ACEA additives A1/B1 or A2/B2 or API SH/CD EC)
5W40 (A3/B3 or API SH/CD EC)
10W40 (A3/B3 or API SH/CD EC)
All oils are good to be used in temperature range from -20C to over 40C)
