I asked Mobil awhile back and out of the blue, ten years later, they responded to a question regarding benchmark tests that Redline and Amsoil use very frequently to advertise there oil. Mobil tends not to market there oil this way, maybe because it won't stack up or maybe what they really believe what they told me:

I don't think this is true about Amsoil not doing any real world testing. The UOA's on this site are becomming a huge asset of real world testing. I thought they run there oils in cabs before releasing them or something to that effect? ?quote:
Amsoils tests that they perform are not API approved tests so they do
not have any validity to them. They also do not perform any real world
testing such as Mobil
