Castrol Axle EPX 85W-140 GL-5 Gear Oil 500ml 3428890
Vehicle Compatibility
This product is a high viscosity axle and differential gear oil selected by specification. Use only where the manufacturer specifies SAE 85W-140 and API GL-5. Confirm the required viscosity grade and GL rating in your owner’s manual before topping up or servicing.
- For axle drives and differentials requiring API GL-5
- Suitable for applications specifying SAE 85W-140 gear oil
- Commonly used in heavier-duty driveline applications where a thicker gear oil is required (confirm spec)
Do not use where GL-4 is specified, and confirm limited-slip requirements if your differential requires a specific friction-modified oil.
