An important detail, AMSOIL products are tested in independent, third-party labs against other popular brands of synthetic and conventional oil. In laboratory tests, AMSOIL consistently outperforms the specifications of other oils and lubricants. But the real test is how consumers respond to the products. With consistent growth over decades, consumers have placed their votes in favor of AMSOIL over other brands by choosing and remaining loyal to AMSOIL for daily use, extreme motor sports, commercial & industrial use, and household applications.

Unlike other oil companies, AMSOIL puts product before profit. It’s a family-owned and operated company, and the management team demonstrates the pride-in-ownership that traditional oil companies lack in corporate America. There are no shareholders to satisfy with profit margins. So, when it comes to quality and performance, you are (hands down) getting the best lubricants on the planet.
