Oh wait there is more. The oil analyst companies offer the ASTM D-4172 test. I knew those scientist were superstitious. Are we having fun yet?TomB said:I just Googled "Mobil 1 four ball wear test scar" and (of course...) got about 70,700 hits ... The first 2 pages were ALL links to different Amsoil distributor sites (most with EXACTLY the same data repeated over and over again ...) with names like 'syntheticoildealer.com', 'bestsynthetics.com', 'eastcoastsynthetics.com', and even 'amsoil.com' ... after 2 pages of this my eyes rolled up into my head and I believe I suffered a mild stroke. After regaining consciousness, I decided that if there is ANY real, independent data out there, I ain't gonna find it on an internet search, because Amsoil has all the search engines stacked.
Marketing and hype, superstition and distinctions without difference ... .
