It helps restore engine performance, improve combustion and prevent new deposits from forming. Suitable for classic Porsche engines.

What Does It Do?

The additive cleans deposits from carburettors and engine components exposed to fuel and combustion.

It helps improve engine performance, maintain compression, reduce the risk of knocking combustion and prevent carburettor icing.

Why Is It Important?

Over time, fuel residues and combustion deposits can accumulate within the engine.

These deposits may contribute to:

  • Rough or uneven engine operation
  • Reduced engine performance
  • Poor throttle response
  • Increased risk of engine knocking
  • Carburettor icing in suitable conditions

When Should It Be Used?

Use as a preventative fuel system treatment or when deposits are suspected of affecting engine operation.

Particularly useful for classic Porsche vehicles with carburettors and petrol engines requiring periodic fuel system maintenance.

Application & Dosage

  • Add directly to the petrol tank.
  • One 300ml can treats up to 70 litres of petrol.
  • The additive mixes automatically with the fuel.
  • Recommended treatment interval: every 2,000km.
  • The fuel tank should be at least half full when adding.
  • LIQUI MOLY also permits direct application to the carburettor, following the manufacturer's instructions.
