I have been doing a lot of searching, and I think I've found the original text that
lazaro's first post was replying to. Let me make clear, I am doing this solely because I want to dredge through the material available and find out the facts. I am not biased in any way, nor am I implying that one brand is superior to another. So please, nobody overreact.
The following is an excerpt from a county website, giving advice on proper car maintenance. It was written by a person named Hib Halverson; who he is or what his credentials are, I have no idea. The closest I could find to the date of origination is February of '99. This is the
actual link to the article in its entirety.
"The results of these tests were just what I expected. While Amsoil might be good stuff coming right out of a bottle; after it's been run in an engine for relatively short periods, it clearly falls short of a lubricant that I would put in my Corvettes or, for that matter, the engines in my other two "beater" cars.
As a manufacturer of high-performance synthetic lubricants interested in making oils that enhance the durability of engines that use them, Red Line does a great deal of testing of antiwear additives, friction reducers and synthetic base oils. There are many components which it could add to its products to make them perform better in ASTM tests on unused oils. However, their goal is selecting a specific oil chemistry that adequately protects a running engine not simply obtaining good test numbers for advertising and marketing purposes.
Red Line had some samples of fresh Amsoil Series 2000 analyzed. Based on that data, they told me they believe some of Amsoil 2000's components are highly chemically reactive, which could allow the oil to react with steel very aggressively in the new oil test and get good numbers. However, when exposed to blowby gases in an operating engine; they think these additives deactivate rapidly, bringing the wear characteristics right back to what you would find with any synthetic oil."
After having read the whole article, I was left feeling that the author was biased against Amsoil, but that in itself doesn't tell me if these claims are fact or fiction. The argument is a sweeping accusation of Amsoil products, while being undescriptive and using very broad terms. I have no engineering background of any sort, so I don't even have a point of reference to start with.
So, I wonder. Is there any validity to this article at all? Does the science back up this man's claims, or is it just twisted data meant to serve a biased opinion?
Furthermore, why can't I be satisfied with ONE oil and stick with it?!
