Always go with what the manufacturer recommends. The additive packages are completely different for LL-01FE & LL-04

For the US and these powerplants BMW recommends a High-SAPS mid HTHS (LL01FE) and a Mid-SAPS low HTHS 20 grade (LL17Fe). BMW will never recommend LL04 because hths is too high which hurts their CAFE rating. LL04 is essentially LL17Fe but with a higher HTHS.
