You're not looking at products that are those that are available in North America, or the correct product, with respect to the 5w30. Castrol 5w-40 and 0w-40 in North America are A3/B4 lubricants, which cannot be dexos1 or dexos2. Castrol has at least least four Edge 5w30 products in North America. There are two SN/GF-5 versions which are also dexos1. There is an A3/B4 version, too, which cannot be dexos, either. Then, there is Castrol Edge 5w30 C3/dexos2, which is, in fact, dexos2 licensed, and available on the shelf, at least up here.
