Grade is going to be irrelevant considering the BMW approval. Isn't it Longlife-01?
Longlife-01 approved oils are disappearing from the shelves, as has already been mentioned the Castrol 0W-40 with Porsche A40 and Mercedes-Benz 229.5 approvals is an entirely acceptable substitute. Mobil 1 0W-40 also has Porsche A40 and Mercedes-Benz 229.5 approvals, buy whichever one you can find cheapest at Walmart.
