Supreme Gear Lube SAE 75w090

Supreme Gear Lube SAE 75W-90 is a parasynthetic, shear stable, thermally stable, thermally durable, multigrade gear lubricant recommended for use in all types of automotive gear drive applications that require a gear oil to operate under severe, wide ambient temperature ranges.

This unique combination provides Supreme Gear Lube SAE 75W-90 with the following advantages:

  • Excellent low temperature properties which results in the bearings and gears being instantly lubricated at sub-zero temperatures the moment they start turning.
  • Superior oxidation stability.
  • Excellent resistance to thermal degradation.
  • Excellent hydrolytic and demulsibility characteristics.
  • Low coefficients of traction, which result in fuel economy benefits.
  • A high viscosity index
  • Compatibility with all types of seals.
