I'm a bit confused by all the different Ford oil specs and what they mean. In particular what is required to meet Ford WSS-M2C913-D and which cars need it.
In Australia we have two full synthetic oils that carry this Ford spec and they are both also rated Euro A5/B5. They are Castrol Magnatec 5W30 A5 it is a Ford WSS-M2C913-D oil and so is Valvoline SynPower 5W30 FE. This SynPower is API SL and ACEA A5/B5, I assume the SL is due to the zinc / phos levels being above the limits imposed on ILSAC oils. The Magnatec A5 has a very high sulphated ash (SA) level of 1.24 %
Valvoline SynPower 5W30 FE says "Suitable for FORD vehicles requiring the latest Ford Fuel Efficiency (FE) specifications"
Castrol Magnatec 5W30 A5 says "For use with Ford Ranger and Mustang Vehicles".
Regular M1 5W-30 claims SN, GF-5, Dexos1, HTO-06, A1/B1 and Ford WSS-M2C946-A & M2C929A (but NOT A5/B5 or M2C913-D).
What do all of these Ford specs mean ?
Both of these full synthetic 5W30 A5/B5 and Ford WSS-M2C913-D oils appear to be locally produced for the Australian market which sort of implies to me that this is what Ford Australia requires in their vehicles. We have no other special, blended for Ford, oils that I know about.
