Okay... but that statement doesn't tell us anything. This whole thread is about what "fully synthetic oil" really means. What are they making it out of? What's the base stock? What are the additives?

This statement from Mobil's website looks promising with the mention of PAO's - but doesn't really give us all the needed information:

q: Is Mobil 1 with SuperSyn Technology a fully synthetic motor oil?
a: Yes, it is. To meet the demanding requirements of today's specifications (and our customers' expectations), Mobil 1 with SuperSyn uses high-performance fluids, including polyalphaolefins (PAOs), along with a proprietary system of additives. Each Mobil 1 with SuperSyn viscosity grade uses a unique combination of synthetic fluids and selected additives in order to tailor the viscosity grade to its specific application.
