The additive chemistry used in the Saber Professional IS tested to the JASO FC and ISO-L-EGD standards, by Amsoils additive supplier. They simply have made a business decision that the ROI wouldn't make it worthwhile to get certification, since so few customers are even aware of certification or care about it. This is a similar situation to some of their engine oils, where they simply choose not to have the product licensed by the API, even though it would easily meet all the performance (wear, deposits, oil consumption, etc), and chemical (phosphorus) requirements.
Amsoil fully warrantees all their lubricants when used in mechanically sound equipment; according to their specific recommendations. In addition, they do extensive bench and field testing before a product is ever released. I cannot recall any performace related issues with any of their lubricants during the 25+ years I've been a registered dealer. This includes their Universal synthetic ATF that some folks have such a hard time accepting.
I should note that the 100:1 mix ratio is for typical homeowner or recreational use. Commercial applications and racing applications should use a richer mix ratio, which is best determined through experience and seasonal engine teardowns....
