Gear Oils

It’s important not to neglect the gears that play a vital role at the core of farming equipment. Using the right gear oils can optimise performance, minimise downtime, prolong gear life – and boost your productivity.
Castrol gear oils have been formulated using the latest thinking in raw materials and then rigorously tested in both laboratory and manufacturing conditions, in close collaboration with leading gear and machinery manufacturers.

Castrol EPX 80W-90

High-performance gear oil
Castrol EPX 80W-90 is designed for use in hypoid, bevel and spiral gear units, axles and final drives operating under severe conditions and over a wide spectrum of operating temperatures.
Through its multigrade viscosity characteristics, it meets the requirements of several automotive manufacturers for cars, vans and commercial trucks or buses. For synchronised manual gearboxes, it should be used only if lubricants of API GL-5 performance level are explicitly recommended for such units.
Features/Benefits
  • Load carrying performance to API GL-5 provides excellent protection to gears operating under the most severe service conditions prolonging the life of components. Multigrade characteristics give wide operating temperature range with particular benefits in low temperature performance.


Specifications and Performance
  • API GL-5
  • ZF TE-ML 05A, 16B, 17B, 19B, 21ª
