AMSOIL 100% SYNTHETIC ATV/UTV CONTINUOUSLY VARIABLE TRANSMISSION FLUID

AMSOIL 100% Synthetic ATV/UTV Continuously Variable Transmission Fluid delivers purpose-built CVT protection for Polaris STEELDRIVE-equipped machines, combining exceptional friction durability with heavy-load film strength that OEM fluids struggle to match in real-world riding conditions.

CVT transmissions in ATVs and UTVs operate under a unique set of stresses. The belt-and-pulley design depends entirely on precise friction characteristics to prevent slipping, and the fluid has to maintain those characteristics while enduring extreme heat from aggressive trail riding, heavy cargo loads, and low-speed, high-torque crawling. Add passengers, accessories, and a few hours of mud or hill climbs, and you're asking a lot from a transmission fluid that most riders never think about until something goes wrong.

EXCELLENT FRICTION DURABILITY
CVTs don't shift gears in the traditional sense. They rely on a belt riding between two variable-diameter pulleys, and the fluid's frictional properties are what keep that belt from slipping. If the fluid can't maintain consistent friction characteristics over time, you get shudder, inconsistent power delivery, and accelerated belt wear. AMSOIL Synthetic ATV/UTV CVT Fluid is engineered with friction properties specifically calibrated for this application, reducing shudder and promoting smooth, predictable operation across the full range of pulley ratios.

SEVERE-SERVICE WEAR PROTECTION
Extreme pressure and high torque during aggressive riding can mechanically shear conventional fluids, causing them to lose viscosity and leaving components exposed. This is compounded when your Polaris is loaded down with cargo, a second rider, or bolt-on accessories that increase overall drivetrain stress. AMSOIL Synthetic ATV/UTV CVT Fluid maintains outstanding film strength under extreme pressure, protecting heavily loaded CVT components even in the most punishing conditions. The Four-Ball Wear Test (ASTM D4172) returned a wear scar diameter of just 0.43 mm, confirming strong anti-wear performance where it counts.

SUPERIOR EXTREME-TEMPERATURE PERFORMANCE
Heat is the primary enemy of transmission fluid longevity. Sustained high-RPM operation, slow-speed technical riding, and hot summer conditions all push CVT temperatures well beyond what casual use demands. When fluid breaks down under heat, it leaves deposits that accelerate wear and degrade shift quality. AMSOIL Synthetic ATV/UTV CVT Fluid resists thermal breakdown with a flash point of 220°C (428°F) and a fire point of 236°C (457°F), helping cool transmission components and extend fluid life. On the other end of the spectrum, a Brookfield viscosity of 9,150 cP at -40°C and a pour point of -46°C (-51°F) mean the fluid flows quickly during cold starts, whether you're riding in late fall or the middle of winter.

HIGH VISCOSITY INDEX FOR CONSISTENT PROTECTION
A viscosity index of 182 means this fluid maintains stable viscosity across a wide temperature range. It won't thin out excessively when the CVT heats up during hard use, and it won't thicken to the point of sluggish operation in cold weather. That stability translates directly to consistent belt grip, predictable power delivery, and reliable protection season after season. At operating temperature (100°C), the fluid holds a kinematic viscosity of 7.4 cSt, while at 40°C it measures 35.6 cSt, both well-suited for CVT pulley systems that demand precise fluid behavior.

SPECIFICATIONS AND COMPATIBILITY
AMSOIL Synthetic ATV/UTV CVT Fluid is designed for use in Polaris STEELDRIVE CVT transmissions. It serves as a direct, high-performance replacement for Polaris OEM CVT fluid and is Warranty Secure, meaning it will not void your factory warranty. For riders searching for a synthetic CVT fluid for Polaris Ranger, Polaris RZR, or Polaris Sportsman models equipped with STEELDRIVE transmissions, this is a purpose-engineered alternative to the dealer-supplied fluid.

SERVICE LIFE
Follow the original equipment manufacturer's recommended oil change interval for your specific machine. Polaris typically specifies CVT fluid changes based on hours of operation or mileage, and adhering to those intervals with a premium synthetic fluid helps maximize transmission longevity.
