Thats kind of right. and LL-1 oil is for the US market with high sulfur fuels. And LL-4 is for the EU market with no to little sulfur in its fuels. But what is also confusing is that the LL-4 rating is also spec'd for a lot of diesel engines.
This is the only document I found at my German BMW dealer...
