GM Engine Oil Recommendation

Time for an oil change. What is the GM recommended fluid? Mobile 1 with the Dexos 1 specification and are all Mobil 1 synthetics made to this specification or do I need to find a specific blend? The manual does not specify.


P.S. Do not use Carl Black in Orlando. No one could answer this simple question and were extremely unprofessional, not greeting me etc.
