Engine Oil & Lubricants - LIQUI MOLY
LIQUI MOLY Cera Tec Wear Protection Additive – 300ml
LIQUI MOLY Cera Tec is a high-performance ceramic engine oil additive developed to reduce friction, minimise wear and provide long-lasting protection for internal engine components.
Its advanced formulation combines microscopic ceramic particles with chemical friction modifiers to help protect metal surfaces, improve smooth running and reduce wear during cold starts and normal operation. Can be used in petrol, in diesel engines and compatible manual transmissions. Not to be used in automatic or PKD gearboxes
Porsche Model Compatibility
Cera Tec is suitable for consideration in Porsche models equipped with compatible conventional oil-lubricated petrol or diesel engines:
These are potential applications based on LIQUI MOLY's general engine compatibility, not individual Porsche model approvals. Check the engine oil capacity, Porsche lubricant requirements and suitability of aftermarket additives before use.
Not intended for the electric drive systems of the Porsche Taycan or all-electric Macan.
What Does It Do?
Cera Tec uses microscopic ceramic particles and chemical friction modifiers to reduce direct metal-to-metal contact inside the engine.
This helps:
- Reduce friction and mechanical wear
- Protect components during cold starts
- Improve engine smoothness
- Provide additional protection under high loads
- Support long-term engine durability
Why Is It Important?
Internal engine components experience friction whenever the engine operates, particularly during cold starts and under heavy loads.
Cera Tec provides an additional wear-protection treatment to complement the engine oil, helping reduce friction between moving metal surfaces.
When Should It Be Used?
Cera Tec can be added during routine engine oil servicing, preferably when filling with fresh engine oil.
LIQUI MOLY states that its protective effect can last for up to 50,000km.
It is a preventative wear-protection additive rather than a repair for existing mechanical damage.
Application & Dosage
- Shake the container thoroughly before use.
- Add directly to the engine / gearbox oil, ideally during an oil change.
- One 300ml container treats approximately 3–5 litres of oil.
- Adjust the quantity for larger Porsche oil capacities.
- Follow the manufacturer's normal oil change intervals.
- Do not exceed the recommended dosage.
Cera Tec is also suitable for certain manual transmissions, pumps and compressors.
Do not use in automatic transmissions, PDK/DCT gearboxes or wet-clutch differentials.
