I don't hate Amsoil. I think their oil is great - top shelf stuff. I just hate the company. KInda like Microsoft. They make some really slick software (NOT Windows!). But their business practices and company ethical standards (at least in the executive suites) are regrettable.
And I do know of many Amsoil claims that were made and never paid - two cases in particular, which seemed to be legitimate. Granted, the vast majority were bogus claims, as is the case in alot of warranty type stuff where scammers try to get money for nothing. But two were valid, or at least seemed legitimate from the info I saw, and Amsoil weaseled out of them. But they are long stories and I will not go into them here.
