If it is labeled as "Technosythese" it is Group 3.
Not sure about the others. I would assume primarily Group 4 PAO.
This is correct. In Europe they have to call it "synthetic technology" if uses as primary base oil, Group III hydro-isomerized petroleum (ultra-refined conventional oil). If labeled as synthetic or full synthetic then would be a Group IV or V base. Or at least that's how it used to be.
