The Energy that Keeps Namibia Moving



Sasol Differential Oil 90, 80W-90 and 85W-140 are sulphur/phosphorus type, multipurpose, extreme pressure gear oils with high load-carrying properties.


Sasol Differential 90, 80W-90 and 85W-140 have been developed for:

  • Spiral bevel and moderately offset hypoid axles operating under various combinations of high speed, low speed, high torque and shock load service conditions.
  • Transmissions of automotive equipment operating under the API service conditions quoted below.

Features and Benefits

Sasol Differential 90, 80W-90 and 85W-140 are NOT recommended for automotive synchromesh gearboxes or final drives where GL-4 oils with milder extreme pressure properties (such as Sasol Gearbox Oil 80W-90) are recommended.

Storage and Handling

  • Use PVC, nitrile or other oil resistant gloves and protective clothing to prevent skin contact. Where eye contact is a potential hazard, goggles should be worn.
  • Avoid temperatures above 80°C and strong oxidizing agents.
  • Ambient temperatures and atmospheric pressures normally encountered within buildings or roofed-over outdoor storage areas are acceptable. Avoid entering areas where mists or vapours have built up as a result of abnormal temperatures or pressures without the proper breathing equipment and protective clothing.
