Benefits and Features

  • Excellent high temperature stability to withstand extreme operating temperature
  • Improved low temperature fluidity
  • Fortified using extreme pressure additive technology to provide excellent protection by reducing wear between gear teeth during high load and shock loading operating conditions

85W-140 Gearbox and Differential Oil

Nulon Gearbox and Differential oil GBD85W140 is an extreme pressure API GL-5 hypoid gear oil, recommended for heavy duty use in most gearboxes, and conventional differentials for passenger cars, trucks, vans, SUV, earth-moving equipment, construction equipment and farm tractors.

Nulon Gearbox and Differential oil is formulated using highly refined base fluids with superior performance additives. It contains a high dose of Sulphur-Phosphorous additive to provide extreme pressure protection for gears and differentials. Nulon Gearbox and Differential oil is designed using high shear stable chemistry to maintain lubricant film thickness. It has corrosion inhibitor additive to provide corrosion protection and rust resistance for gearbox components.

Nulon Gearbox and Differential oil is designed to improve wear protection, corrosion resistance, anti-scoring properties, oxidation and thermal stability. It has excellent protection against thermal degradation, component wear, and oil seal deterioration.

For enhanced anti-wear performance use Nulon G70 Manual Gearbox & Diff Treatment.


  • Excellent high temperature stability to withstand extreme operating temperature
  • Improved low temperature fluidity
  • Fortified using extreme pressure additive technology to provide excellent protection by reducing wear between gear teeth during high load and shock loading operating conditions
  • Improved corrosion protection and rust resistance to protect gearboxes and differential components
  • Outstanding shear stability to maintain film thickness under heavy duty operating conditions
  • Compatible with automotive seals and gaskets to prevent leakage

  • Manual gearboxes, axles, final drives and conventional differentials where API GL-5 is recommended
  • Passenger cars, 4x4, light commercial vehicles, SUV, medium trucks
  • Hypoid gears that experience high load and shock loading where lubricant film strength is crucial, such as in most rear-wheel drive vehicles
  • Gears that experienced high speed and/or low speed and high torque conditions
  • Final drives used in heavy trucks, construction and farm equipment that require speed reduction and torque increase for heavy duty application
