The sad thing is that many ignorant assumptions will continue since more people will read a thread asking if anyone loves Mobil1 instead of a thread containing data. Adding that my engine didn't blow up using M1 was just to get more views. Otherwise, it would get only about 50 views.
I love the Widman viscosity graph. Sometimes we debate over 2-3 cst's at 100C when the viscosity in freezing temps and below have a much larger gap! As the graph shows, the first number in a multi-viscosity oil does not tell you the actual viscosity at a given temp and does not mean than a 0W-x is thinner than a 5W-x.

His uoa sample was obviously
tainted with a bit of virgin oil or some Pennzoil Ultra.
