Due to inconsistent sulphur levels and ethanol BMW specs LL01 for gassers in North America. US diesels use LL04.

The oil and BMW filter cost $63 and change for me at New Century in Alhambra after 10% off for being a BMW Car Club member. Still saved almost $30....
LL-04 is for diesels, as I understand. (I think it has something to do with higher level of ZDDP additive, but don't quote me on that.)
I don't use stabilizers, and haven't researched them. I don't think they are necessary if you use the right oil in the first place. Use the extra money on the right oil, I guess.
If I had bumped into a thread about overheating I would ask if you had work done on the cooling system. As I know there is a special bleeding procedure, (and tool to use, some sort of pump that you pressurize the system to a certain level,) to do when adding coolant after cooling system work. If I remember correctly I had to detach a coolant hose to install the oil cooler retrofit. I then had a performance power kit installed by a dealer since I knew they would have to bleed the system anyways...
