Frequently asked questions

What is EP80W90 Gear Oil 73020005 used for on a Land Rover?

This is an extreme-pressure API GL-4 gear lubricant for manual gearboxes, transfer boxes, and axle differentials on older Land Rover models. The EP80W90 grade protects gear teeth and bearings under load. It fits Series, Defender, Discovery 1 and 2, Range Rover Classic, and Range Rover P38. Cross-references: GA4965, DA1532, LR003156.

What's the API specification for this gear oil, and does it suit limited-slip differentials?

This gear oil meets API GL-4 specification. GL-4 is the standard spec for most older Land Rover manual gearboxes and transfer boxes. Check whether your differential or axle application requires GL-4 or GL-5, as some limited-slip differentials and specific axle units call for GL-5 rated oil instead.

How much gear oil does a typical Land Rover differential or gearbox take?

Capacity varies by unit. A 5L container typically covers multiple components in one service, such as both differentials and the transfer box on a Defender or Discovery. Always fill to the level plug rather than by volume, and confirm the specified oil type in the workshop manual for your specific unit.
