Is this something you just made up? Any labs produce these results?

How much would you like? we have been collecting UoA's for almost 10 years now....... Mobil 1 started going to Hell when Exxon bought them in 1989. They have been consistently reformulating Mobil 1 products into lesser performers, some even losing all their ACEA ratings in the process. The current version of 0W-40 took several attempts before it regained any ACEA ratings, and then only just. Mobil 1 once was a great product; unfortunately it no longer is.
There are several great full synthetics available that simply put Mobil 1, particularly their 0W-40 grade, to shame in just about every category, particularly the “ability to stay in grade” under high temp/high shear conditions, which the current Mobil 1 is very poor at.
