We tried Castrol, Pennzoil (not LL01 , different viscosities) same effect as BMW oil.
So don't bother yourself to spend a lot many just buy case in Costco and you good to go, believe me. We did this for last 3 years of testing.
Thanks for your input phlfly, and can I confirm that you meant LL04 and LL01 as BMW spec below says LL04. Also, which filters did you guys used?

Longlife-04 engine oil SAE 0W-40
Trade name BMW part number Container size
BMW engine oil Longlife-04 83 21 0 398 504 1 litre

Longlife-04 engine oil SAE 5W-30
Trade name BMW part number Container size
BMW engine oil Longlife-04 83 21 0 398 507 1 litre

Anyway, so far the list is below;
1. Castrol Edge Titanium 0W40 oil + BMW oil filter
2. Mobil 1 0W-40 + Hengst Filters
3. Mobil 1 5W-30 (claimed to be tested best)
