Do your next blackstone in cold weather and have the engine idle for 10mins for you send the oil.
Essentially you're saying: run the engine in conditions that cause fuel in your oil and then you'll see fuel in your oil. Is this supposed to prove that 0W40 is wrong for the car? Run 10W60 under the same conditions and you'll see fuel in your oil as well, I would think.

Here is what Kawasaki (the racing engine designer and builder) had to say in that M3 thread about the scary bearings.

A little something to add, I have been running the 0w40 mobil for a while now. I installed a gauge in the car to monitor OP. So far so good. I have got it to about 240 on the oil and still have 35psi at idle. At 210 oil I have 40psi. Full hot (240) is 80 at 8500 and 210 at 8500 is around 85-88
In conclusion the pressure is just fine for what we need. Although every car could be a little different I will have no problem running this oil from this point forward.
I never checked the pressure before the gauge install but now that I know there is good pressure I will never go back.

For information, I found the thread where I read about the BMW engineer here:

Some thoughts by one of the M engineers:

Quote:
I was fortunate to attend a BMW sponsored track day a few years ago and they had a factory engineer/advanced driver from Germany in attendance.
I and others were able to pick his brain through out the day and the 10W-60 spec oil of course came up. The real concern of most was the use of that oil in our Canadian winters.
He justified it's use in M engines when specified, for track days like the one we were currently enjoying and high speed driving when oil temps can easily exceed 150C.
He was asked to define high speed driving and he said sustained speeds in the 250 kmh range. When asked, what if you don't track your M3 and never exceed 150 kmh? He honestly found the question puzzling and answered "why would you buy an M3 if you didn't plan on driving it fast; there are other less powerful but more suitable 3 series choices available"? I told him my dentist who had an M3 was typical of most M3 owners in N/A. He likes the performance looks of the car, the status of it but he's never driven it faster than 140 kmh and typically cruises in the 120 kmh range. He found this 'poser mentality' very strange but agreed an M3 driven in such a manner would never see higher oil temps than a regular 3 series BMW and consiquently the regular BMW spec' oil would be more appropriate.
