Looks great, thanks for the contribution of info.
This is a great oil right here! Thanks for doing all of this for us. Definitely makes the site more interesting and informative. I hope to add to the list soon. Thanks a lot brother!
Why change a winning formula?
DING DING DING! Healthy traditional package on that puppy. I suppose the 40 is not constrained by ILSAC resource conserving ash limits.

I was told SN oil does not have a Max Zinc level. This oil is SN
mmmmm

Just to clarify, there's no API SN limit on Zinc, but rather Phosphorous; which limits Zinc indirectly. And yes this 0W40 does comply ... since the P limit doesn't apply to this grade.

Lots of boron considering its' low atomic weight of 10. Boron compounds potentiate normal Zn/P AW effects.
My Delvac 1 SHC has only 1189 ppm Zn but 245ppm B.

What do you all make of the fact that the 0W-40 SN does not seem to be adopting the reduced calcium/additional magnesium that the other SN grades have? Is it due to Ash limits as ArcoGraphite suggested? If so, since 0W-40 SN retains the more traditional additive package, does this suggest the reduced calcium/additional magnesium is compromised in other areas in order to meet reduced ash levels, since 0W-40 SN is sticking with the conventional package?
^Probably to still meet the requirements of the various Euro specs, for now? Just a guess.
High boron is common in motorcycle oils.

That is a good question, one I'd like to know. I think it is due to the lower ash limits. What is odd though is the 15w50 looks like all the other M1 oils. The 0w40 is different.
