At the end of the day, Amsoil is nearly double the cost of the other oils, and this test is not much of a selling point unless you need an oil that can stay in grade with dilution.
So the expensive $$$$ engines aren't prematurely wearing out because you aren't running Amsoil? Hard to believe.
You will feel better spending twice as much for the oils trust me !!
