85W-140 Gearbox and Differential Oil

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.

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
  • 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

What is a hypoid gear oil

10 months ago

A hypoid gear oil is a lubricant that is designed to operate effectively with hypoid gear designs. Most gearboxes and differentials use hypoid gear designs and the lubricant must contain EP (extreme pressure) additives to prevent wear between the sliding surfaces of a hypoid gear mesh.

Related Questions

Is synthetic oil better than mineral oil

10 months ago

Synthetic base oils have a number of advantages over mineral base oils. The uniformity of the synthetic oil molecules improves the thermal stability and reduces oxidation of the oil. Controlled molecular structure also results in lower volatility and a more stable vicosity over the life of the oil.
