The other thing that gives me pause in that there is in fact conflicting information. Here is a link to the Toyota website:

They claim that 10k miles is the right number. Obviously they have also done their own studies yet they come up with a different number.
Mercedes and Audi also recommend 10k miles. Based on that information, i'm just not sure about the 15k interval. |
Why would you use an oci formulated for a Toyota or an Audi for a BMW? Different oils, different engines, sump capacity, etc. Toyota says use 5w20 oil. Are you using that as the "right oil" for your BMW? Audi and Toyota are Simon Pure while BMW are capitalist swines? Why not use the mfr oci recommended by Cummins (hey, hey, usa, usa) for their heavy duty diesels: 35,000 mi?
