Amsoil guarantees the performance of its products, so you can be confident they perform as advertised. Amsoil introduced the world’s first API-qualified synthetic motor oil and has since introduced a full line of industry firsts. For more than 40 years, Amsoil synthetic lubricants have proven themselves in the lab, on the racetrack and on the highway.
You can also be confident that using Amsoil synthetic lubricants or practicing extended drain intervals will not void your new vehicle or equipment manufacturer’s warranty.
In fact, it is against Federal law for an original equipment manufacturer (OEM) to deny warranty coverage based solely on the brand of lubricant used. The Warranty Secure symbol informs consumers of this fact. Using Amsoil synthetic lubricants in place of OEM-branded lubricants, or practicing extended drain intervals when using Amsoil lubricants, does not void new vehicle or equipment manufacturer warranties.
Amsoil stands behind its products and the people who use them. If the OEM claims use of Amsoil products violates the warranty, contact Amsoil Technical Services (715-399-TECH). For complete information on Amsoil warranties, contact Amsoil Technical Services.
