The 0w20 Amsoil was stable, I am impressed with that. It is 8.9 and the top of viscosity for 20 weight is 9, so that oil had like no shear off. I do like the use of heavier oils as well documented here, but as far as that oil goes, looks good. What you may want to do is try 30 weight and see if the wear numbers come down, that is what I did. I didn't get a real definitive result though.
