No. -B1 just has the SN+ LSPI test, thats all, as timing chain wear is still a year or two away when the upcoming GF-6 happens.
The WSS Ford spec family has never been much to write home about.

No, Ford avoids the GM dexos1 and dexos2 specs due to proprietary intellectual property legal issues and corporate rivalry. Ford
should unify on GM's better dexos specs, but won't for obvious reasons.

So what you are saying is an oil that is GM Ford, Chrysler specs as well as any other spec is just GM spec? No it is an universal oil intended to be used in multiple vehicles. If GM spec oil is so good why not get AC Delco oil as this is true Dexos with not having to meet other manufacturers spec.
