Hydraulic Oil MG

Product code : (HCZMG)

  • Resists oxidation and corrosion to help extend component life
  • Fights sludge to help maximize system cleanliness and operability
  • Provides strong wear protection to help maximize pump and motor life for reduced maintenance
  • Ensures good filterability for optimal fluid performance and life

Hydraulic Oil MG

AMSOIL Industrial Hydraulic Oil MG is a value-based conventional oil formulated to protect high- and low-pressure gear, vane and axial piston stationary and mobile hydraulic systems. This zinc-containing formulation resists oxidation, fights corrosion and inhibits foam.


  • Formulated with quality base oils and anti-wear additives to protect pumps, motors, valves and other components against wear.
  • Helps hydraulic systems operate as designed, reducing maintenance
  • Fights sludge to help maintain cleanliness and operability


  • Anti-foam agents provide maximum fluid efficiency, reduces sponginess, and helps prevent cavitation that can damage hydraulic pumps, motors and valves
