Preferred Customers purchase AMSOIL products at wholesale cost, which is approximately 25 percent less than suggested retail. Six-month trial membership can only be purchased once; after the trial membership, Preferred Customers need to renew on an annual basis to maintain Preferred Customer status. Annual memberships can be renewed indefinitely.

Instructions: Click “ADD TO CART,” then proceed to “CHECKOUT.” You will be prompted to submit additional information and AMSOIL will provide everything you need to get started.
