It's the correct sheet, as SR5 pointed out. Castrol in North America, in addition to listing A3/B4 right in the product name, also tends to list "North American" or "European" or something similar on bottles where there may be ambiguity based solely on viscosity grade. I've seen 5w30 SN/GF-5 Edge bottles here with "North American" to distinguish them from the A3/B4 versions.
There was more than enough confusion several years ago with people running 0w-30 ILSAC Castrol in VW engines that should have been using GC 0w-30 A3/B4, so the labelling is intentional. No one in North America, aside from a BITOGer, looks beyond the 5w30 when they buy oil, which makes them likely to pick up City Star and other PQIA Hall of Shame varieties, let alone the A3/B4 they should actually be using.
I know way too many "car guys" here who state that a 5w30 is just a 5w30 no matter what.
