You are going to get whooped up here big-time
I will say that in regards to the UOA testing... You would actually need 30 or more consecutive runs with just 1 oil to have a significant enough of a baseline for a comparison... And then 30 or more consecutive runs with that second oil.... And that's a minimum of what you would actually need... Probably should be 40-maybe 50 of each... to be truly statistically meaningful and reliable.
And that telling wear by UOA even by performing the above 30+ runs consecutive runs on each oil would be questioned by some... . .
I tend to think weighing parts before and after 30+ runs with one oil would be more telling...
Even with all of that done like that.... There are still other big variables that can make it nearly impossible to come up with a fair level field comparison between two oils.
