For high-performance racing applications, AMSOIL DOMINATOR® Synthetic Racing Oil is the go-to choice. This specially designed oil not only provides maximum horsepower, but also offers superior engine protection. It's no wonder that Team AMSOIL relies on this exact same oil to secure their victories and championships.

AMSOIL DOMINATOR® Synthetic Racing Oil is specially designed for racing engines and is fortified with zinc and phosphorus additives to protect critical surfaces from wear. Its unique friction modifier provides superior protection against extreme temperatures, resulting in cooler-running engines and maximum power. Additionally, DOMINATOR is shear-stable, ensuring that it maintains its performance even under the most demanding racing conditions.


What Makes DOMINATOR Different?

AMSOIL DOMINATOR® Synthetic Racing Oil stands out from other oils due to its high levels of zinc and phosphorus additives, specifically zinc dialkyldithiophosphate (ZDDP). ZDDP is a powerful anti-wear agent that not only reduces friction but also protects against corrosion and oxidation. This makes DOMINATOR the ideal choice for high-performance racing engines that require maximum protection and performance.

Another reason AMSOIL DOMINATOR® Synthetic Racing Oil stands out from other oils due to its unique formulation. One key ingredient is ZDDP, which creates a protective film on metal surfaces to reduce friction and wear in high-pressure conditions. This film also helps prevent corrosion. Additionally, ZDDP acts as a friction modifier, increasing lubricity for maximum horsepower and torque. It even acts as a sacrificial anti-wear agent, reacting with the metal surface to create a chemical barrier that prevents direct contact and metal-to-metal wear.

Superior Protection

When it comes to racing vehicles, superior protection is essential. These high-performance machines have modified engines that produce extreme heat and pressure, far beyond what the average car or truck experiences. For instance, a Pro 4x4 race truck can generate over 900 horsepower and reach engine oil temperatures of more than 300ºF (149ºC). To withstand these conditions, top-of-the-line protective measures are necessary.

When it comes to protecting your engine, it's important to consider the temperature at which your oil operates. While a typical passenger car or light truck may see engine oil temperatures below 220ºF (104ºC), racing engines can reach much higher temperatures. This is significant because the rate of motor oil oxidation, or breakdown, doubles for every 18ºF (10ºC) increase in oil temperature. In other words, racing engines can experience oil breakdown more than 16 times faster than a typical vehicle. That's why it's crucial to choose an oil that can provide superior protection under extreme conditions.

When it comes to racing oil, superior protection is crucial. The oil is subjected to immense pressure and shearing forces as it flows between the main and rod bearings and cam lobes and lifters. This can cause the oil's molecular structure to break down, resulting in reduced viscosity and film strength. To prevent this, high-quality racing oils are formulated with additives that provide superior protection under these extreme conditions.

AMSOIL DOMINATOR® Synthetic Racing Oil is designed to provide superior protection for engines that experience extreme shearing forces. Its unique formula is specifically formulated to withstand the demands of high-performance racing engines, ensuring maximum protection and performance.

At What Cost?

When it comes to engine modifications that increase power, there is often a trade-off between performance and protection. DOMINATOR®, however, offers an extra layer of safeguarding for engines that operate under extreme conditions. Racing oils like DOMINATOR® are designed to provide maximum performance and protection under high pressure and heat, but only for a limited duration. So, the question remains: at what cost are you willing to push your engine to the limit?

When it comes to motor oil, there are always tradeoffs to consider. DOMINATOR®, a high-performance racing oil, is specifically designed to provide maximum protection during intense racing conditions. However, this level of protection comes at a cost - DOMINATOR® doesn't contain the same additives found in passenger car motor oils that help with fuel economy, engine cleanliness, cold-weather operation, and extended oil drain intervals. So while DOMINATOR® may not be the best choice for everyday driving, it's the perfect choice for those who demand the most from their engines on the track.
