DOMINATOR\u00ae 15W-50 100% Synthetic Racing Oil<\/strong><\/h3>\n

Product Overview<\/strong>
AMSOIL DOMINATOR\u00ae 15W-50 Synthetic Racing Oil is specifically designed for racing engines. It provides maximum performance and superior engine protection under extreme racing conditions \u2014 including intense heat, extremely high RPMs, and shock-loading \u2014 which are all common during competition.<\/p>\n

\n

Key Benefits<\/strong><\/h3>\n

Maximum Engine Wear Protection<\/strong>
Racing engines are typically modified to deliver significantly higher horsepower and speeds than standard engines. These modifications result in increased shear forces, which can cause oil viscosity to break down. Viscosity loss can lead to increased wear on bearings, cylinders, and other critical engine components.<\/p>\n

AMSOIL DOMINATOR\u00ae 15W-50 is engineered to resist viscosity breakdown caused by shear. Its durable oil film continues to protect under extreme stress. The formula is fortified with high levels of zinc<\/strong> and phosphorus<\/strong> anti-wear additives to help guard against scuffing and component wear in racing conditions.<\/p>\n

    Maximum Horsepower<\/strong>
    AMSOIL DOMINATOR\u00ae 15W-50 is friction-modified to reduce drag inside the engine, enabling maximum horsepower output while simultaneously lowering engine temperatures. Unlike conventional oils, this specialized formula is built to handle extended high-RPM racing intervals and helps extend the life of high-performance engine parts.<\/p>\n

    \n

    Applications<\/strong><\/h3>\n

    AMSOIL DOMINATOR\u00ae 15W-50 is suitable for all types of racing, including circuit racing, rally, off-road, and powerboat competition. It is ideal for engines that require a high-viscosity SAE 50-grade oil.<\/p>\n
