Some Castrol and Shell products use Gp IV and V, as well as severely hydrocracked Gp III. Some Mobil and Amsoil products are Gp III, some may well be Gp II. They all make a range of oils at various price levels. The 0w/30 Castrol oil is, I think, a Gp IV oil, as mineral derived oils are unlikely to achieve 0w/xx viscosity. It fully meets your preference for a full synthetic. So, why decry Castrol or Shell? I have no connection with the firms BTW: just curious about the stance.
