Will report back on further impressions as I drive thru the next 5k OCI.

I just switched my S55/M3 and my N55/335i to Motul 5W40 too and I'll be sampling both after 5,000 miles.
FWIW.... my N55 loved Molygen 5W40...as reported from its latest Blackstone report.
The engine has had 13 oil changes with LM 5W40 with 67,000 miles of daily driving.
