Oil approval question

[map76]

Hello everyone. I have a question. If a particular oil meets Ford's WSS M2C945-A specification; does it also meet the WSS-M2C930-A specification as well? I believe the 930-A is an older specification. I have a 2005 Mercury Mountaineer that has the Ford 4.6L v8 in it, and this engine requires the WSS-M2C930-A specification. Thanks

945-A supersedes 930-A. 930-A is for Sm oil while 945-A is for Sn oil.
