AMSOIL Racing Oil delivers the ultimate protection and performance demanded by high-output engines. Its synthetic formulation provides exceptional film strength that resists viscosity breakdown under extreme heat, RPM, and load, ensuring vital components stay protected even in the harshest racing environments. 

Designed for superior shear stability, it prevents metal-to-metal contact, reducing wear and extending engine life. The advanced additive chemistry, including high levels of zinc and phosphorus (ZDDP), offers robust protection for aggressive cam profiles and valvetrain components. 

AMSOIL Racing Oil also maintains internal cleanliness by controlling carbon and deposit buildup, preserving horsepower and consistent compression. Its molecular uniformity enhances cold-flow performance for quick oil circulation at startup while maintaining thermal stability in intense heat. 

Whether it’s drag racing, endurance events, or snow-covered circuits, AMSOIL Racing Oil delivers consistent performance, superior wear protection, and unmatched reliability—giving racers the confidence to push harder and finish stronger. 

AMSOIL Racing Oil has earned its reputation as a benchmark in motorsports for one simple reason—it performs where other lubricants fail. Under the brutal combination of high heat, high RPM, and extreme load, it maintains its strength and stability. Whether it’s powering cars down drag strips, enduring the relentless pace of endurance racing, or tackling frozen snowmobile circuits, AMSOIL Racing Oil consistently proves its worth. The science behind synthetic racing lubricants has transformed how racers think about protection and performance, giving teams and individual enthusiasts the confidence to push their engines to the edge.

Racing engines endure conditions far beyond what street vehicles experience. High compression ratios, extreme cylinder pressures, and elevated temperatures demand an oil capable of resisting shear, oxidation, and breakdown. AMSOIL’s synthetic base oils and additive packages are engineered specifically for this challenge. Unlike conventional oils, which degrade quickly under stress, AMSOIL Racing Oil maintains its viscosity, ensuring the film strength necessary to prevent metal-to-metal contact. This durability gives racers the confidence to push for more laps, more power, and more reliability, whether in a turbocharged import or a naturally aspirated V8.

Viscosity stability is a key advantage of AMSOIL Racing Oil. In racing, oil can thin dramatically under mechanical stress, reducing protection and accelerating wear. AMSOIL’s Dominator series resists this breakdown, keeping a stable protective film through intense heat and high RPM conditions. Endurance racers value this stability over long events, while drag racers depend on the oil’s ability to handle shock loading during violent acceleration. In both extremes, it delivers unwavering performance.

In cold-weather racing environments such as ice tracks and snowmobile circuits, oil flow at startup is critical. AMSOIL Racing Oil’s molecular consistency allows it to remain fluid in sub-zero temperatures, circulating quickly to protect vital components. Its 2-stroke racing oil formula burns cleanly, minimizing deposits in exhaust ports and power valves—a vital factor for consistent performance in cold climates. Conversely, in hot-weather racing, synthetic base stocks resist oxidation and breakdown better than mineral oils, maintaining protection even under relentless thermal stress. This stability ensures consistent horsepower and long-term engine cleanliness, keeping engines running strong from start to finish.

Internal cleanliness is another defining trait. Racing engines often run rich fuel mixtures and high compression ratios, creating conditions for carbon buildup and deposits. AMSOIL Racing Oil incorporates detergents and dispersants that control contamination without compromising film strength or foaming resistance. The result is a cleaner engine, more stable compression, and longer component life—benefits racers can feel in every lap.

Each AMSOIL Racing Oil formulation serves a specific purpose. The SAE 60 version is designed for high-output drag racing engines needing maximum film thickness, while lighter blends like AMSOIL Dominator 5W-20 provide rapid acceleration and minimal drag for applications where every fraction of a second counts. The company’s synthetic break-in oil is tailored for new racing engines, allowing proper ring seating while still offering crucial protection against premature wear.

High concentrations of anti-wear additives, including ZDDP, form a sacrificial layer that guards against wear in aggressive camshaft and valvetrain setups. This chemistry, combined with consistent viscosity and cleanliness, makes AMSOIL Racing Oil a complete solution for professional and amateur racers alike.

Ultimately, AMSOIL Racing Oil stands as more than just a lubricant—it’s a performance component. Its ability to deliver exceptional film strength, resist viscosity loss, flow effortlessly in the cold, and remain stable under heat has made it indispensable in motorsports. From drag racing to snowmobiling, racers trust AMSOIL to protect their engines and preserve performance when it matters most.
