No worries man! Thankfully I have a great SA, so even though I had already told him all was OK, I went back to him again and asked him to actually change it to the right fluid. So all good, They are changing it to the proper fluid as per this thread.

Thanks again!!

Here in Spain BMW uses 0w30 M engine oil. Although some years ago it was 5w30.

As long as it's LL-01 you should be good.

I've seen oils with this certification ranging from 5-30, 0-40 and 5-40. I've also used them all over a wide range of usages (street, track, 100F+ ambient heat) and run UOA on all of them. They all come back fine (other than Motul X-cess 5-40 tending to shear) which has led me to conclude that it doesn't really matter.
