Product Description

Mobil SHC Aware™ H Series lubricants are high performance, anti-wear hydraulic oils for modern high pressure hydraulic systems that meet the U.S. Environmental Protection Agency (EPA) 2013 Vessel General Permit (VGP) guidelines for “environmentally acceptable lubricants”. They provide excellent wide temperature range performance above and beyond the capabilities of non-synthetic environmentally acceptable oils. Mobil SHC Aware H Series oils are specially formulated from ester base stocks and provide exceptional anti-wear and film strength characteristics necessary for hydraulic systems operating under high load and high pressures.

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
