I see Shannow reguarly refer to this stuff as A3/B4 so did some digging. I take it the 5w-30 at Walmart https://www.walmart.com/ip/Castrol-Edge-5W30-Motor-Oil-5-qt/34039135 is not the same as http://msdspds.castrol.com/bpglis/FusionPDS.nsf/Files/CBF55E354ED8B47E80257D540060FC09/$File/BPXE-9P9HK3.pdf available in other parts of the world?
