AMSOIL synthetic lubricants contain no contaminants or molecules that don’t serve a designed purpose. Their versatility and pure, uniform molecular structures impart properties that provide better friction-reduction, optimum fuel efficiency, maximum film strength and extreme-temperature performance conventional lubricants just can’t touch. Conventional lubricants, are refined from crude oil. Contaminating elements such as sulfur, nitrogen, oxygen and metal components such as nickel or vanadium are inherent to crude oil and cannot be completely removed through the refining process. The oil refining process separates the various types of molecules in the oil by weight, leaving molecules similar in weight but dissimilar in structure, reducing performance.
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.
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.
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.
