I would really be interesting in knowing what sorts of testing they do besides UOA's. Mobil's tech center in Fairfax is way bigger than Amsoil's whole orginization. The idea that Amsoil is constantly testing new formulations is laughable. They dont have the ability to formulate there own base oils and additives so what would the point be? Basicly from a formulation standpoint Amsoil typicaly buys a decent base oil and combines it with a very robust additive package of the traditional, ZDDP, calcium type. This approach is fine and dandy but it also insures they will never be certified, even if they did submit their oils for testing, which they refuse to. its also avery crude, low tech approach compared to what Mobil , Shell or Chevron do. Off course this is as applys to 4 cycle oils.
A few of Amsoils two cycle oils MIGHT pass some of the standards but that would be only Interceptor for Jaso FC and HP injector for TCW3. None of the rest of their two cycle oils are even remotely close to passing. Imagine what the deposit test would look like after 100:1 was ran through at a 16:1 ratio? Or what about the smoke test ran at the same ratio?
