So I missed the chance to do this with the M2.

Ah too bad, thanks.

I asked Blackstone about this subject for the S55 since I too missed catching a sample at the 1200 mile oil change on my M2C. Here's their reply when asked about how S55 factory fill samples they've tested compared to "normal" 0W30 BMW oil samples:

I did some poking around in our database, and most factory oil samples from those engines show a viscosity in the 0W/30 range. The additive package is also similar to BMW 0W/30 oil samples we've tested. It's a reasonable assumption to say they leave the factory with BMW 0W/30, but it's hard to be totally certain. The measured viscosity of similar grades, such as 5W/30, are about the same as 0W/30. I will say there is nothing terribly remarkable about the factory oil from those engines. It doesn't have an "odd" additive package or relatively thick for thin viscosity compared to the recommended 0W/30.
