WOLF GUARDTECH 80W GL 4

This is a gear oil for mechanical transmissions with moderate "extreme pressure" characteristics and is specifically developed to avoid corrosion of copper alloys.

It is suitable for the lubrication of syncromesh gearboxes, transfer boxes, mechanical steering controls and most rear axles (certain rear axles should be run in with a GL5 oil).

This oil contains robust components, which provide reliable lubrication, reduce oil degradation, and contribute to a long and reliable service.
