Re: Please enlighten me, RU saying 5W30 is too thin(m
However, the BMW "Service and Warranty Information" booklet that came with my US 2000 5401a specifically said the following 3 oils are approved by BMW:
1. BMW High Performance 5W-40 Synthetic Oil (PN 07 51 0 002 545)
2. Mobil 1 5W-30
3. Mobil 1 5W-40
If the M1 5W-30 is not suitable for their engines, why was BMW officially endorsed it ?
