Just trying to find an approved oil for the above car. I keep getting lost in technical details when searching, and the BMW list keeps changing. Had been using M1, but since it lost LL-01 I've used pennzoil platinum euro 5w40 and castrol edge 0w40 (I thought I had used 0w30, but when I double check it looks like only the 0w40 is LL-01). Are these both appropriate? Usually 1 or the other will be on sale with a filter at my FLAPS...
