Perhaps it is the Court that err'ed, not Castrol.
If the courts of jurisdiction had made Castrol, and others, market the product as: "Faux Synthetic" or "Group III Synthetic," or similar, then the buying public would be notified that there is some sort of difference between the Group III and Group IV synthetics, and a downward price pressure would naturally develop on the Group IIIs. Everyone would have benefited, as the buying public (including many BITOGers) would have opted for the fine Group IIIs at the relatively lesser price, and others would pay up for the "better" PAOs. The Castrol lawyers must have walked away from the judgement shaking their heads at the Court's supidity and their good fortune.
