AMSOIL 20W-50 100% Synthetic Hydrostatic Transmission Fluid

Synthetic, high-zinc formula fights wear. Built for hydrostatic transmissions to maintain mower speed and efficiency better than motor oil. Promotes long transmission life for professionals who depend on their equipment to make a living.

Maximizes Mower Speed and Responsiveness

• Zinc-based additives fight wear to maintain motor-wheel tolerances and proper oil pressure.
• Resists viscosity loss in extreme heat for maximum mower speed and responsiveness.

Commercial-Grade Wear Protection

• Forms a thick, durable film on gear teeth and other components to guard against metal-to-metal contact and wear.
• Resists mechanical shear and viscosity loss for excellent wear protection and long transmission life.
• Maintains protective viscosity despite extreme heat to ensure strong protection.

Maintains Cleanliness

• Naturally heat-resistant synthetic base oils help reduce deposits.
• Promotes component cleanliness for peak efficiency and excellent performance season after season.
