I suspect that Valvoline condensed his email into that format. Most of the FAQ's are like that.
I don't believe that PAO is listed in the MSDS. They are only required to list hazardous chemicals, and they don't even list mineral oil % in the US MSDS.
In the Japan MSDS they do have to list mineral oil, but not PAO. Mobil 1 in Japan apparently has about 40-50% mineral oil (probably hydrocraked Group III), about 10-15% additives, and the rest undisclosed (probably PAO/ester base).
