In Germany that oil is sold as Full Synthetic. You cannot sell oil in Germany under 'full synthetic" label if it does not contain 50%+ of base oil that is either PAO or Ester.
We are getting same oil here. Also, pour point indicates PAO base.
For example Mobil1 sells M1 0W40 in Germany as SHC oil, while in the U.S. it sells as Full Synthetic.
That is not to say that HC oils are bad, or that M1 with its VISOM base is bad, but my point was that in Castrol hierarchy Magnatec falls below Edge. It uses cheaper mineral base stocks, while Edge is using PAO. As far as I heard, M1 is also returning to PAO for 0W40.
