Among the Mobil 1 0w40's, the ESP X3 and C40 GT are the most shear stable. The Supercar 0w40 was tested for 24 months with GM through track use. The Supercar 0w40 is a nice oil. Notice all but the FS 0w40 contain some ester.
Another interesting Mobil 1 oil that gets overlooked is Mobil 1 Truck and SUV. Contains AN and is more shear stable than regular Mobil 1.
For those that think these are just run of the mill oils, take a look at this article. These oils exceed specifications.
