A single sample analysis of unused oil is hardly difinitive on which is superior. Beside more isn’t always better. It’s how the different additives work together. Another thing to keep in mind is, in the chemical industry, not all additives of the same name are created equal. They can have vastly different quality and specifications.
Fouling out cats with excessive anti-wear additives is a real issue as well, and I am a little surprised that wasn’t highlighted a bit more. Amsoil sells an oil very similar to the Redline, but doesn’t recommend you use it in an emission controlled vehicle for this very reason.
