In other words, in your mind its a conspiracy theory. Bull!S&!. There is no oil that can magically go 25,000 miles, at least not at the consumer level. Perhaps 6000, although for the price your paying there would be no reason to avoid selling it if your a dealer, the markup more than makes up for the lesser oil changes. The real issue though is that as I understand it, Amsoil itself is set up as a MLM, not as a retail operation, so the reason its not carried in stores is because that is not their chosen distribution method, not because there is some conspiracy to suppress a superior product.
Until today I'd not heard about Amsoil. But much like the K&N thread, just reading this and the nature of the testimonies set off alarm bells, and after some research online I realized just what a scam this stuff is. Every review I can find is put up by someone out to promote the product, there are dozens of website with scare tactics to get people to use it(good example here:
http://www.lessforeignoil.com/content.php?content.4 ), tons of purportedly independent 'reviews' that are on websites clearly designed to look independant but when I read them its obviously marketing, major disputes on their Wikipedia entry from people who are upset that Amsoil or their dealers have turned thier entry into a commercial, and lots of talks of conspiracies, wierd references to the Mobil1 vs. Castrol court case(which near as I could tell had absolutely nothing to do with Amsoil) as though it somehow legitimizes it, and people making plainly ludicrous claims about what it does for their engine.
Seriously, even if the stuff is pure gold and will give me 50mpg and an oil change every million miles I don't think I could bring myself to support this kind of behaviour with my hard earned money. Might as well toss it out to Scientology, Amway or whatever other scams are out there. Which, btw, is interesting since apparantly Amsoil has branched out into nutritional supplements, another disreptuable MLM heavy money maker.
Thanks, but no thanks. I have some sense of morals and ethics, and am not nearly this easily scammed.
