1. It is high HTHS oil with some 4.4cp. N54 needs 3.5-4cp. What you doing is creating unnecessary heat and drag. Your turbos need bit more time to spool. Basic rule if lubrication: as thin as possible, as thick as necessary.
2. Sport is only API certified, which mean Noack limit is 15%. N54 has issues with CBU and you might be contributing more than necessary.
3. BMW engines are oxidation monsters. Sport is ester based which means it has higher oxidation than street oil.
Sport is good oil if you spend a lot if time at the track and when I mean a lot, I mean every weekend.
Get Castrol Edge 0W40!

What do you think of the Castrol Edge 5w-40 Euro that is LL01 sold at walmart and others? |
Mediocre.
Pennzoil Platinum Euro 5W40, Motul X-Cess 5W40 GEN2, Quaker State Euro 5W40 (repackaged Pennzoil) and Valvoline European Vehicle 5W40 are all better.
QS Euro goes $18 for 5qt on Wal Mart web site.
