About this item

Custom-Built to Outperform
AMSOIL Signature Series 100% Synthetic Motor Oil is formulated for drivers who demand the absolute best engine protection. Built with advanced synthetic base oils and a precision-engineered additive system, it is designed to control wear, resist volatility and maintain viscosity under extreme heat, pressure and cold-start conditions. The result is uncompromising film strength, cleaner components and protection that pushes beyond industry standards into a class of its own. Modern engines place unprecedented stress on motor oil through turbocharging, direct injection, higher temperatures and extended service intervals. Signature Series is engineered to meet those challenges head on, delivering more protection, performance and confidence mile after mile, even during extreme use.
See the Product Data Bulletin for full details.

Guards Against
Low-speed pre-ignition (LSPI) remains a serious concern in today’s turbocharged, direct-injection engines, where uncontrolled combustion events can damage pistons and other critical components, especially as motor oil ages. AMSOIL Signature Series 100% Synthetic Motor Oil is engineered to help prevent LSPI by maintaining a strong, stable formulation that continues to deliver outstanding performance throughout the drain interval. Even after 25,000 miles of use, Signature Series delivers 4X more piston protection against LSPI4 than the industry standard requires.
