But, at least they have something to do with the relevant spec in the product name and on order sheets. If I want a 5w-30 A3/B4 from Wakefield Canada, there is no ambiguity. I won't accidentally select ILSAC 5w-30 or C3 5w-30, since they don't use weird lettering in product names and require a subtitle for people to somewhat figure it out. Castrol sells at least 7 versions of 5w-30 here, with GTX, HM, black bottle ILSAC, gold bottle ILSAC, A3/B4, C3/dexos2, and Elixion E6. There's no ambiguity for the line items.
