I've been trolling the internet for the last while and come across quite a few oil "tests" , where people use bearings under pressure to convince viewers how well a certain oil works. Royal Purple tends to be one common oil that tests out well in these experiments.
To the untrained eye they seem legit, but how well to such tests equate to the quality of a motor oil ?. I know Amsoil pushes the size of wear scars on their 4 ball tests, but is there a relationship between wear scars on bearings and the ability of an oil to provide reduced wear ?. I just picked out two such tests, but there are hundreds out there, some seem to be done well and many do not.

Thanks for reading, and any replies on this.
