In fact, the Mobil 0W-40 held up better than many other oils in 4-ball testing. 4-ball testing is very similar to the test presented in your link.

Yes, I remember you posting somethig like that on BITOG site. Do you have any pictures? I guess the main test was between Mobil 1 0W-40 versus Mobil 1 5W-40, not against Royal Purple, etc, right?
From what I read, Mobil 1 used to publish this industrial standard data on their oil's specs like Amsoil and Redline. However they stopped doing it and said it was not relavent. The coincidence is that Mobil 1 was beaten by Amsoil and Redline on this particular test.
Now I am hearing that Amsoil is also not providing this on some of their oils. (I have never used Amsoil.)
