I don't know. BUT...
IMHO this is NOT where I would try to save a little cash. I bought my oil, filter etc. from my BMW dealer. If there is ever any question about whether I used the right oil, filter, etc. I can show them the invoice.
FWIW I am very conscious of anything that could possibly give a dealer or BMW an excuse not to honor the warranty. On our old E53 I installed a 3rd party battery. But I ended up having to replace it with a BMW battery a year later. Not because it was defective, but because the dealer would not even attempt to repair an electrical issue under warranty, unless the battery was a BMW approved part.
