I keep reading here and elsewhere that only in the US can Grp III oils be marketed as synthetic. As far as I can tell, some european countries have specific legal language that prevents GrpIII from being marketed as synthetic. However, it seems that in much of the rest of world "synthetic" oil can be based on grp III. Does anyone here KNOW how extensive the ban on Group III as synthetic really is?
I know the story about the NAD evaluation of Mobil vs Castrol. I also know that in that case it was shown that Mobil had been marketing GrpIII in oils labelled as synthetic in some parts of the world at the time of the dispute. I am not trying to re-live this argument. I am trying to find out the extent of the GrpIII as synthetic ban. Clearly, it is not only the US that allows GrpIII oils to be marketed as synthetic.
