Wear metals are sub-micron, about the size of the additive package components. Bypass filters do not remove them. If you had particles large enough for bypass filters to remove, you would be buying a new engine soon.
When Gulf Coast and Amsoil were about the only two players in the market for these, people thought up all kinds of strange rumours, like they would filter out the additive packages.
Someone once said "The difference between a new engine and a worn-out one is only a few thousands of an inch".
I have posted that I would like some assurance that what I buy next month is the same as I got last time,
In response to this. Great for you. Seriously. But if I was happy with a product and the next time I went to buy it, they told me, we tweaked the formula and made it even better, but it doesn't cost you anymore, I certainly wouldn't turn it down.
We like to see better quality products in everyday life from detergents to cars, to tvs, but we want the same motor oil from the 50's? Or would you rather they just improved when you approved of it?
I just happened on this thread and it still amazes me of those that spend soo much time putting down a product they have never used. If you don't like a brand of camera, but you have never used it, do you go out of your way to bash it? Probably not.
it's this simple. If you don't want to use it, don't. If you want to "trust" Amsoil as some of you call it, go for it. hundreds of thousands of users can't be all stupid and 30 years would definately show a trend, if one existed. The only trend that continues seems to be the non-users bashing a product with no more information than what in most cases was put in thier head by an oil competitor, or the auto parts store guy who makes a few bucks an hours and has never even seen a bottle of Amsoil.
This post will not stop it, nor will anything else. The fact is Amsoil has grown by over 20% annually for the past few years. It will continue to do so without your support. Amsoil is not for everyone. It doesn't have to be.
