LIQUI MOLY Top Tec MTF 5200 75W-80 Gearbox Oil  ›  LM10

Always check the required Porsche oil specification and viscosity for the individual model before ordering.

Its formulation provides a stable lubricating film, excellent wear protection and corrosion resistance while helping reduce running noise and improve gear-changing performance.

What Does It Do?

This gear oil lubricates gears, bearings and transmission components, reducing friction and wear while supporting smoother gear changes.

Why Does Gear Oil Deteriorate?

Common causes include:

• High operating temperatures
• Contamination from internal wear
• Oxidation and ageing
• Moisture ingress
• Extended service intervals

When Should It Be Replaced?

Replace according to the vehicle manufacturer's service schedule or if the oil becomes contaminated or degraded.

Difficult gear changes, gearbox noise or excessive metallic particles in drained oil should be investigated.
