  • Excellent anti-wear performance protects components within hydraulic systems and reduces operating costs by extending pump life and minimising downtime.
  • Excellent Hydrolytic Stability improves the protection of yellow metal components, even in the presence of water, extending component life.
  • Good thermal and oxidative stability extends oil life reducing operating costs.
  • Good Sludge and particulate control maintain system cleanliness extending filter life and reducing filter change frequency.
  • Excellent filterability.
  • Good anti-rust and anti-corrosion properties protect the system.
