I don't want to argue about why the m5 does what it does that wasn't the point. The point is that there are many cars that have an ecu that have parameters and limits based on oil temps. Those parameters and their purpose will vary from one vehicle to another. As for your car and your data... Enjoy it, I don't really take it as any worthwhile information. I will rather take the word of industry professionals who have said so, and my own experiences that also prove it.

If you think you have nothing to gain by cooling your oil, than go ahead and run it as hot as you like. There's nothing left to debate. I hear you clearly that you don't wish to believe it, that's just fine with me. Carry on, there isn't anything left to say about it.
