Protect your Engine

Hand-in-Hand Protection

The AMSOIL DOMINATOR Racing Oil is engineered from advanced synthetic technology to better withstand the elevated rpm, high temperatures and shock-loading common to racing applications. Its robust formulation, tested and validated by championship race teams, is designed to provide maximum horsepower without sacrificing engine protection. DOMINATOR provides straight-grade protection in a multi-grade formulation. AMSOIL DOMINATOR® Synthetic 10W-30 Racing Oil (RD30) provides superior performance and maximum protection in high-performance and racing applications.

Anti-Wear Formulation

Racing and high-performance engines are typically modified to deliver maximum horsepower and speed. Their powerful designs create shearing forces that can cause lesser oils to lose viscosity, leaving bearings, pistons and other components vulnerable to wear and failure. DOMINATOR Synthetic Racing Oil's durable formulation resists viscosity loss due to mechanical shear to maintain a strong protective oil film. It is heavily fortified with zinc and phosphorus anti-wear additives to provide additional protection against scuffing and wear in severe racing conditions (see results below).

The piston crown contains normal carbon, while the rings remain clean and functional. Note the absence of wear or scuffing on the piston skirt.

The camshaft shows little-to-no scoring, bluing or wear after 3,000 miles of high-performance racing.

AMSOIL DOMINATOR DOT 4 Synthetic Racing Brake Fluid

Precisely tailored to the needs of auto enthusiasts and dedicated racers, the Dominator DOT 4 Synthetic Racing Fluid meets the highest DOT standards (5.1) and is the perfect choice for high-performance passenger-car, light-truck and powersports applications. DOMINATOR DOT 4 Synthetic Racing Brake Fluid features the ultra-high boiling point required during extreme racing conditions.

Provides vapor lock protection through high boiling points while resisting brake fade common in racing applications for a confident brake feel all the way to the finish line. It's also engineered with a nitrogen blanket to avoid moisture absorption and prevent contamination during manufacturing and storage, ensuring top-quality fluid upon purchase.

Break-In Oil

AMSOIL Break-In Oil is an SAE 30 viscosity grade oil formulated without friction modifiers to allow for quick and efficient piston ring seating in new and rebuilt high-performance and racing engines. It contains zinc and phosphorus anti-wear additives to protect cam lobes, lifters and rockers during the critical break-in period when wear rates are highest, while its increased film strength protects rod and main bearings from damage. AMSOIL Break-In Oil is designed to increase compression, horsepower and torque for maximum engine performance.

The primary goal during engine break-in is to seat the rings against the cylinder wall. Properly seated rings increase compression, resulting in maximum horsepower; they reduce oil consumption and prevent hot combustion gases from entering the crankcase.

Combine these three products to maximize your performance on and off the track while maintaining a high protection for your engine.
