Not only this, Amsoil oil comes with a warranty, so even if there is any damage caused to the engine after using Amsoil oil, the company would pay for the repairs.


As mentioned above, although Amsoil claims its products have met and even exceeded the recent industry standards, including Dexos 2 and Dexos 1 Gen 2, neither the company nor any of Amsoil’s products is listed in the list of Dexos Approved brands.
