I've used it in various flavors in different cars since the middle 80's when I had my SAAB 900S. I admit to trying other brands at different times, but consider all of the oils I've used to be quite good (M1, GC, PU, PP, Edge). I've tried to stick with LL-01 for the BMW, but now that the approvals have been dropping, I've just figured 229.5/A40 is certainly good enough for a 20 year-old 5 series. That said, just yesterday I did an OC and swapped out Edge Euro for M1 Euro because of the generous rebates from Mobil and Walmart.
