That is part of the debate. No one really knows. Posts have been made that the LL-01 spec covers more than just the oils ability to stay in grade for 15,000 miles. It would appear that many people have gotten away with using non LL-01 oils...so the choice is really yours. I have occasionally strayed from using non LL-01 oils on rare occasions. In fact I have Mobil 1 5w-30 in my car now...but I never go more than 7500 miles.
As much of this thread shows, it is much debated, and "up to what you are comfortable with". BMW is clear on their recommendations...
