Ever since the Castrol and Mobil incident with the BBB deciding in favor of Castrol it seems that ideologies have triumphed over common sense. The current system calls Group I, II, and II+ as conventional, any combination of Group III and Group I, II, or II+ as synthetic blend, any combination of Group III and Group IV or V as Full Synthetic also called "not a real synthetic" by those who disagree with the BBB's decision.
In order to make these arguments go away, and as a step to make oil purchasing less confusing for those who may not be 'in the know' aka the average consumer, I think there should be a revision in how an oil is marketed/labeled. In my opinion the following might be a more appropriate method of labeling motor oil.
Any combination of Group I, II, and II+ should be conventional.
Any combination of Group III, IV, and V should be syn-blends.
Any combination of Group IV and V should be full synthetic.
What do you guys think?
