  • Axles, final drives and power take-off units in trucks, buses and off-highway vehicles used in various industries, including the construction, agricultural, forestry and mining sectors.
  • Differentials, gear boxes and steering gears, where a hypoid oil is required.
  • Some industrial gear sets, where an extreme pressure (EP) gear oil is required.



Excellent extreme pressure and antiwear performance protects gears operating at high speeds and tooth pressures
from abrasion, wear and welding, even in severe high-load and shock-loading conditions, extending component life.

Excellent thermal and oxidation stability minimise the build up of deposits and varnish, reducing wear, extending
component life and ensuring a longer oil life.

Protection against corrosion and rusting extends equipment life and reduces maintenance costs.

Good low-temperature fluidity ensures optimum lubrication, even in cold start-up conditions, and prevents start-up

Good anti-foaming properties ensure optimum oil film thickness, protecting components against wear, and minimise oil leakage.

Available in five viscosity grades to meet the specific needs of the application.

Multi-grade oils can be used over a wider temperature range, and so can reduce the need for seasonal oil change thus reducing maintenance costs.

Fully compatible with common seal materials, to extend seal life and prevent fluid leakage.
