This weekend I was in Munchen for the Welt 3.0 Meeting/car show... while I was there I stopped by the factory run BMW dealer down the street from the Welt. I took some pics of the factory motor oils that BMW sells here in Germany.
They had two oil grade viscosities for the N54/N55 engines:
5w30 fully synthtic LL-4 rated oil: #83210368607 price 29.38 euros per liter
0w40 fully synthtic LL-4 rated oil: #83210368504 price 28.89 euros per liter
The Castrol TWS 10w60 oil is only for the M3(e46/e9x) and M5/M6 (e60) models.
