The BMW announcement leaves no room for the interpretation given by your local dealer. The BMW annoucement says:
BMW Long-life rating LL-01 Synthetic Oils for BMW M vehicles equipped with S54, S62, S65 or S85 engines
This DOES include the S65 (NA engine), and does NOT include the S63 or S55 engines (FI ///M engines used in turbo M5/M6 and upcoming M3/M4). Furthermore, the BMW announcement clearly says for cars in production at the present time (August 2013). That latter clause would exclude the turbo S55 engine in the upcoming M3/M4.

See above. LL01 specifically allowed for S65/S85 engine. S63 and S55 engines (new FI turbo ///M engines) are not mentioned at all, where other specific engines (S65, S85) are directly mentioned. Very clear to me this announcement does not intend to target S63/S55 because those engines are never mentioned; but does intend to target S65/S85 as those engines are specifically mentioned for LL01.

Are we to believe that each and every single one of those cars were abused?  |
I track bearing wear causes and photos in this thread.

I include all engines whether modified or not. But the article which discusses cause and effect concentrates on stock (unmodified) engines, and unmodified cars.
