I've used 5W-30 in all my BMW's and never had any engine issues. I'm confident BMW knows whats best for their engine, they are savvy and top performers in many of the famous performance races around the world.
I use BMW 5W-30. The brand doesn't matter, it's the level of specification that matters and most oils sold in America don't meet that. Majority synthetic oils are classified ACEA-1 and BMW recommends ACEA-3. Only a few oils are BMW approved in America, and I still don't prefer to use them because it's either LL-01 Castro Syntec 0W-30 or Mobil 1 0W-40. I prefer not to cheap out on oil and just use what BMW sells, so I order it from Tischer in bulk.
