Always check the required Porsche oil specification and viscosity for the individual model before ordering.
Its Total Drive Line (TDL) formulation combines excellent wear protection, stable viscosity and smooth gear-changing performance, even under demanding operating conditions and fluctuating temperatures.
What Does It Do?
This gear oil lubricates gears, bearings and transmission components, reducing friction and wear while supporting smooth gear changes and reliable differential operation.
Why Does Gear Oil Deteriorate?
Common causes include:
- High operating temperatures
- Heavy mechanical loading
- Contamination from component wear
- Moisture ingress
- Extended service intervals
When Should
It Be Replaced?
Replace according to the vehicle manufacturer's service schedule or when the oil becomes contaminated or degraded.
Gearbox noise, difficult gear changes or excessive metallic particles in drained oil should be investigated.
