When you say "actual unbaised tests," what do you want to see tested? Each manufacturer provides many specifics, are you talking real world application? In that case, oil analysis is the closest you can get, but has WAY too many variables that will ultimately affect the results.

As I have said an uncountable number of times, I am not here to defend or to push AMSOIL. These are just MY experiences with AMSOIL, Mobil 1 and other engine oils, and their manufacturers. In fact, I used to be a HUGE supporter for Mobil 1, and used their products religiously. It wasn't until I started doing so work with some Formula SAE engineers on a Formula SAE race car, that I learned just how much better AMSOIL is (both on the paper, and in real world applications).
