here's the exact quote from BMW site:

That's odd. Does it also list ACEA specifications? I thought BMW had done away with API ratings by the time SM came around. So, it's okay to use SL GC on a newer BMW that calls for the BMW specifications, but not an older BMW that calls for API SM? How very strange.
Yeah, all sorts of mistakes on that BMW page, unfortunately. For example, the Valvoline SynPower SAE 5W-30 that they're recommending does not carry an LL-01 spec. It's the Synpower HST 5w-40 that does, but good luck finding it in a container smaller than a 55-gallon drum.
