Can anyone explain the usefulness of this test ?, or should we not judge an oil based on results of that test ?. Firstly, I respect Amsoil as a good quality fluid. But, there are two things that irritate me about Amsoil. Firstly is they have so many freakin distributors that any time you do a web search on ATF or other fluids, 25,000 out of 26,000 search results turn out to be Amsoil dstributors advertising and you have to weed through to get to the 1000 non-amsoil results. Secondly, is the 4 ball wear test they plaster all over the place. It gives you so little information that I am reluctant to believe in any of that information. Plus you see crap products like Prolong abuse that test all the time claiming no measurable scar wear - that's when you get into all the cheater additives like bleach , coke , or whatever it is that gives false results. We now see a post on Redline compared to Amsoil in the 4 ball wear test, what do we make of that test. I am surprised Redline spent the time to engage in that test. Any info would be cool. J.
