AMSOIL Synthetic Multi-Viscosity Hydraulic Oil’s blend of high-viscosity-index base oils and performance additives provides all-season protection and reliable operation in all types of hydraulic systems. Its proven wear resistance and varnish-control deliver maximum hydraulic system performance and life. Synthetic Multi-Viscosity Hydraulic Oil is additionally tailored to promote energy efficiency and foam suppression.

All-Season Performance
Multi-Viscosity Hydraulic Oil is designed for all-season use. Each viscosity covers a broad operating temperature range, helping eliminate seasonal oil changes. Its low pour point ensures the oil flows more readily in cold temperatures than petroleum oils. Bearings and other components receive almost immediate lubrication at start up, reducing long-term wear and instances of pressure spikes and erratic operation as a result of poor fluidity. At high operating temperatures, Multi-Viscosity Hydraulic Oil resists thermal breakdown and maintains its protective viscosity, allowing formation of a strong lubricating film.

Varnish-Control Technology
Increased heat can cause varnish to form on metal surfaces, including valves, pumps and bearings. Its soft, sticky composition ultimately hardens into a harmful veneer that can reduce fluid flow, plug filters, stick valves and increase friction. Synthetic Multi-Viscosity Hydraulic Oil is fortified with anti-varnish additives that chemically react with the building blocks of varnish, inhibiting its formation. It helps hydraulic systems remain clean and long-lasting.

  • Increases convenience and reduces costs due to all-season performance
  • Formulated to reduce maintenance costs with anti-wear and anti-varnish chemistry
  • Promotes maximum fluid life by resisting viscosity loss and chemical breakdown
  • Designed to increase system performance and responsiveness through foam suppression and fast air-release properties
  • Helps reduce energy costs due to high-viscosity-index, energy-efficient formulation


Anti-Wear Chemistry
Synthetic Multi-Viscosity Hydraulic Oil features a shear-stable formulation fortified with the latest zinc-type anti-wear additives. It meets the stringent viscosity retention requirements of Parker Hannifin (Denison) HF-0 and demonstrates excellent anti-wear performance and compatibility with yellow metals in standardized laboratory and pump manufacturer tests (see below). Synthetic Multi-Viscosity Hydraulic Oil demonstrates excellent protection for pumps, motors, valves and other components against wear.
