I picked up some bulk oil from a seller on the forums and got a mix of TWS 10w60 and Edge 10w60. Both say that they are formulated for M engines.
However, the BMW part number on the Edge is different (83 12 2 219 730) and realoem.com indicates this to be for a BMW motorcycle (HP2 Sport K29).
Now I know Castrol is in the midst of re-branding all their synthetic oils to EDGE and was wondering if some of you have started getting this oil from your dealers as well?
Here are side by side pics -
