high pressure gearbox oil 80W90, 1 L, 911/912/914 (65-86)

The lubrification of older generation gearboxes (Porsche 356, 912 ,911 up to the 1986 year-model)is mostly carried out by oil wading inside the transmission case.

Overtime if the gearbox oil level is not checked or if no oil changes are made, moving parts are no longer properly lubricated. This will cause excessive wear of transmission components, bearing noises, abnormal play between components, etc….

This recommended high pressure transmission oil acts by lubricating transmission gear sets through capillary action, protecting them under the most extreme uses.

Allow an average of 4 liters of oil per gearbox.
