here's a reply back from exxon-mobil, regarding mobil1 5w-30 sold in the US:
The Mobil1 5W30 motor oils is factory filled with the Corvette (meeting their tough standards) and many other GM factory fill standards, all API "SM" requirements and it also meets the tough ILSAC GF-4 approvals. Formulating the Mobil1 5W30 motor oil to meet the newer BMW requirements would mean losing other approvals listed above and we are not willing to do that.
