Okay, here is why I ask this:
Castrol has previously said that the USA 0w-30 is the same as in Europe, and now we find that the GC formulation has apparently changed (gold to green, different add pack, etc.).
So, since USA 0w-30 appears to be group III, is there some basis to conclude that the new gold GC (not the 04 green stuff) is likewise group III?
