This is a very confusing issue for a lot of us. I would like to put the signature or XL series oil in my 2012 V6 mustang but I've received a lot of conflicting answers on whether doing so may cause warranty issues.
The sig series oils meet Ford WSS-M2C945-A specs BUT, there is no API certified logo on the container. the fact that there is no API logo, may cause Ford to deny a warranty claim.
an entire thread about this was opened up at a mustang forum, and no one is the wiser for it unfortunately.

what an absolute joke all of this bureaucratic nonsense is.
consider the fact that the 2011 mustangs were required to meet Ford WSS-M2C930-A. The amsoil XL line meets that spec, and has the API logo. Now this is where it gets crazy. The 2012 mustangs must meet the new Ford WSS-M2C945-A spec. The 2011 and 2012 cars are the exact same cars, but now require different specs. This means that anyone who wants to use the XL oil is now potentially vulnerable to denial of claim!
I spoke to Josh at amsoil several times and he confirmed the potential warranty issues with the current reality. He thinks that the XL lime should be labelled for the new spec by the end of the year.
Can anyone get an answer from ford on these issues?
