I think he means "No effin' Way"
And I agree. It was first rumored that Mobil 1 SS was Mobil going the route so many other mass market synthetics have, the dark Group III path.
However, this is not the case. It is still a PAO & ester blend (Group IV & V) with an improved barrier package over the marginal Tri-Synthetic.

I thought Lakespeed Jr. from JGR summed it up nicely.

Mobil 1 definitely uses a PAO and ester base oil, not a group 3.
How did you confirm that?
I believe Mobil's evasive answers along with the spectrograph evidence strongly suggests that some grades of Mobil 1 do utilize some Group III in the base oil blend.
