And the cost for API license is $360,000 for one test alone, and you can be looking at another $100,000 after the initial $360,000. I personally think the European oil certification is much better than ours!!! And I am not a big fan of Amsoil and their marketing system, but they do have a good product.moisheh wrote:
Amsoil dealers are like aluminum siding salesman and they are certainly not lube engineers. If you want an expert try one of the oil companies. A real oil company not Amway, oops I mean Amsoil.

Plus a lot of their oils are not API approved---------so, if are under warranty, you could get screwed.
The other option (that a lot of oil packagers use) is to just mix in an already approved additive package into their base oil (synthetic or dino). No need to repeat the API testing.
Without the API logo on the container, who knows what is really in the container (and I would never trust an oil salesman on that).
