Product Information

Features and Benefits

  • Meets US EPA 2013 Vessel General Permit requirements for environmentally acceptable lubricants
  • Outstanding load-carrying and anti-wear properties which protects system components against wear and scuffing and helps provide long equipment life
  • Shear stable high viscosity index help sustain component protection over a wide temperature
  • Excellent thermal /oxidation stability that can help reduce maintenance downtime and costs by contributing to system cleanliness and deposit reduction, enable long oil and filter life
  • Excellent demulsibility ensures ease of water removal in below waterline applications
  • Good elastomer compatibility, it works well with same elastomers used with conventional mineral hydraulic oils


  • Marine controllable pitch propellers (CPP) systems, fin stabilizers, deck equipment, hydraulic systems where spills or leakage could result in adverse environment impact
  • In systems where readily biodegradable and minimally toxic fluids may be required
  • Circulation systems containing gears and bearings where mild extreme-pressure characteristics are desired
  • Systems containing servo-valves
  • Hydraulic systems operating with oil temperatures in the range of -30C to +100C
  • Marine and mobile equipment operating in environmentally sensitive areas
  • Circulation systems operating under mild to moderate service conditions
  • Industrial hydraulic systems where leaked or spilled fluids could get into plant effluent
  • Air line oilers and some limited oil-mist generating systems
