Let's not forget that there are oilers owners reading this forum, and LL-04 is required for us (F3x 28d, E90 335d, E70 X5d, even F10 35d.) You can actually use LL-04 in gasoline engines, but you can't go the full 10K/15K OCI and must sample your oil to determine the lifetime (they start with a lower TBN). My guess would be a 5K or 7.5K OCI would be ok in a gas engine with LL-04.
All this is going to change as EPA ratchets down the allowed sulfur in gasoline in the next few years.
On the viscosity front, BMW's LL specs restrict the stated viscosity range to 0 or 5 on the cold side, and 30-40 on the hot side. There's hardly a difference IMHO on what you choose.
