High-Zinc Formulation Fights Wear and Helps Preserve Mower Speed and Responsiveness
AMSOIL 20W-50 Synthetic Hydrostatic Transmission Fluid is specifically formulated to deliver smooth, responsive operation in zero-turn mowers, stand-on mowers and other equipment professionals rely on to make a living. It fights wear and viscosity loss during continuous, severe-service operation, maximizing mower speed and operability. Unlike motor oils, AMSOIL Hydrostatic Transmission Fluid is purpose-built to withstand the unique demands of hydrostatic transmissions. It lasts up to 2X original equipment manufacturer (OEM) recommendations, helping professionals save money and reduce downtime.
Maximizes Mower Speed & Responsiveness
In many zero-turn mowers, oil pressure drives the wheel motors. Fluid that fails to protect against wear can cause the tight tolerances in the wheel motors to widen, which reduces oil pressure and erodes speed and responsiveness. Fluid that thins at high temperatures can have the same effect. AMSOIL Hydrostatic Transmission Fluid contains high levels of zinc-based anti-wear additives to help maintain those tight tolerances, while its synthetic base oils naturally resist viscosity loss in extreme heat. As a result, it helps maintain mower speed and responsiveness for increased productivity.
Commercial-Grade Wear Protection
Transmission fluid must form a thick, durable film on gear teeth and other components to guard against metal-to-metal contact and wear. The mechanical action of meshing gear teeth, however, can tear apart – or shear – the molecular structure of the fluid, leading to viscosity loss. High heat can also cause the fluid to thin. The thinner fluid can fail to protect against wear, reducing mower life and increasing maintenance costs. AMSOIL Hydrostatic Transmission Fluid’s naturally tough synthetic base oils resist viscosity loss due to shear and high heat, promoting the formation of a durable sacrificial anti-wear film on components that helps extend mower life.
20W-50 Synthetic Hydrostatic Transmission Fluid
• Fights wear for smooth, responsive operation
• Purpose-built to outperform motor oils
• Resists high heat and shear
High ambient temperatures, combined with hydrostatic transmission temperatures that can exceed 230ºF (110°C), cause some conventional fluids to break down and form harmful deposits. AMSOIL Synthetic Hydrostatic Transmission Fluid features naturally heat-resistant synthetic base oils, which reduce deposits and help keep equipment clean and running properly season after season.
