I use the Castrol Edge, its expensive but the oil is considered very good 20000 kilometers between oil changes
it has to be.
I cant remember of hand but have a look at the Castrol website and ONLY use ford recommended oil for this engine
as the engine dosen't like any other.
I have a 2.2 on an 07 prefacelift which takes 6 litres I dont know the amount for the 2 litre
