AMSOIL DOMINATOR® DOT 4 100% Synthetic Racing Brake Fluid - 12 oz Bottle

AMSOIL DOMINATOR® DOT 4 100% Synthetic Racing Brake Fluid is a premium synthetic racing brake fluid engineered for high-heat braking systems and extreme motorsport applications that require DOT 4 brake fluid. AMSOIL positions it for superior high-temperature performance, strong pedal feel, and resistance to brake fade and vapor lock under severe racing conditions.

Designed to maintain stable braking performance under extreme pressure and heat, this fluid delivers ultra-high boiling points and stable viscosity across a wide temperature range. AMSOIL also says a nitrogen blanket is added to each bottle during manufacturing to help purge moisture and preserve performance.

Built for serious racing use, this brake fluid is ideal for performance vehicles and track applications that need stronger high-temperature brake fluid performance than standard street-focused fluids. AMSOIL says to use it in racing applications requiring DOT 4 and recommends changing the fluid once a year for maximum performance.
