This is at the heart of the situation in the USA. Currently LL01 is what is recommended but with the coming diesels they will require LL04. LL04 is currently only available in the EU/elsewhere b/c the US has inconsistent sulfur content which (so I have been told) creates an issue with certain types of oil. This will all be addressed shortly by BMW USA on the website... I will keep you updated as we get closer!
