confused about oil specification

I've got a 2013 with a 1.5TDCi 55kw (UGJC) engine.

I know it uses 5w30 but should the oil be  WSS-M2C913-C  or  SS-M2C913-D?

What's the difference between the two?

cheers

    Could be D has superseded C ? i use Petronas SYNTIUM 5000 AV - 5W30 on my 1.5tdci.

    Oils are usually backwards compatible, so the later spec should be fine to use

    Thanks for posting!

    I've read that WSS-M2C913-D is backwards compatible on to WSS-M2C913-C so presumably WSS-M2C913-D has a better additive package.

    I suspect for a given grade and specification, all oils are on par. The oil brands buy in base stock from the refineries, additive packages from chemical companies, then blend the ingredients into the required oil.

    So could the D spec extended service be applied to any modern Ford diesel such as the UGJC engine ?
