Plus, every one of the long paragraphs and or pages does the noncommittal dance.
Everyone, insofar as they have exonerated their answer or abdicated it.
They do the word-sald type rope.
Blah blah
I will keep researching for another day or so.
Any helps is appreciated

I think your best bet is to try to ask someone like Lake Speed or see if you can get a response from Amsoil.

When I was looking at the first link, it looks like the Euro stuff is slightly heavier than the SS, and the blurb below the chart says the same, that the cold start performance of the SS is a little better because it's thinner, and the Euro stuff maintains its viscosity better at higher temps. To me it sounds like the two oils may be a tiny bit different in viscosity (but both within 5W30 spec).

I know that in the videos, Lake Speed Jr has mentioned that the base oils can be better and some have more esters which makes a difference, but I don't remember the specifics of either.

What I did to find the charts for the additives of the 2 Driven oils above is a google search for "driven virgin oil analysis" (and several variations and similar searches). I was able to find a bunch of folks that had posted their results on various forums. Maybe you could do similar searches and find results that showed more of info about those oils.
