Some hydraulic applications require use of highly biodegradable hydraulic oil due to government regulations or environmental concerns. Vegetable-based biodegradable oils, however, often provide good biodegradability but compromise performance in other areas. AMSOIL Biodegradable Hydraulic Oil is designed to offer the best of both worlds. Its synthetic formulation delivers the ideal combination of excellent biodegradability and wear protection for mobile and stationary hydraulic applications.

Maximum Protection

Biodegradable Synthetic Hydraulic Oil provides excellent wear protection for hydraulic pumps and motors. It maximizes component life to help reduce time and money spent on maintenance.

Reduces Environmental Impact

Biodegradable Synthetic Hydraulic Oil is readily biodegradable, with an environmental persistence classification of Pw1, the fastest and highest level of biodegradation. It helps reduce environmental harm in the event of leaks or minor spills.

APPLICATIONS

Use AMSOIL Biodegradable Synthetic Hydraulic Oil as a replacement for most synthetic and conventional hydraulic fluids in stationary and mobile applications using gear, vane and piston hydraulic systems operating under high pressure and high temperatures. Typical applications include construction, logging and farming equipment, lawn and turf care or anywhere leaking, spills or ruptured hydraulic lines may present an environmental hazard.

Applications & Recommendations

Biodegradable Synthetic Hydraulic Oil is compatible with most synthetic and petroleum-based hydraulic oils. Mixing AMSOIL oils with other oils, however, will shorten the oilÂ’s life expectancy and reduce its performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed. To ensure proper performance, it is recommended systems be drained and flushed prior to installation.

  • Resists oxidation for long oil life
  • Guards against wear
  • Helps reduce harm to the environment
