I have continued to use Castrol Edge 0W40 even after Castrol (and Mobil) got rid of the LL01 rating. The Castrol 5W40 now showing up at Walmart does carry the LL01 rating. It is about $22.xx a 5qt (liter?) jug. Even without the LL01, I figure if it meets MB, Porsche and VW specs over the same period, then I would use it.
