Correct but it doesn't have anything to do with the HT/HS since LL-01 and LL-04 have the same requirement. It's solely about the SAPS level.The thing is that BMW has never officially back spec'd LL04 in the US for petrol cars probably for regulatory reasons. Beginning around 2015 they moved to sub 3.5 hths 30 grades (LL01FE for N-series gas engines and LL12FE for N47/57 diesels ).
