Product Information

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.

Key Features

  • Advanced ceramic wear-protection technology
  • LIQUI MOLY product reference 3721
  • 300ml container
  • Reduces friction and internal engine wear
  • Helps protect during cold starts
  • High thermal and mechanical stability
  • Compatible with commercially available engine oils
  • Suitable for compatible turbocharged engines
  • Compatible with catalytic converters and particulate filters
  • Long-term protection for up to 50,000km
  • Suitable for compatible manual transmissions
  • Not suitable for wet-clutch applications

  • Porsche 944 2.7L 8V 1988-89
  • Porsche 928 4.5L 1978-82
  • Porsche 928S 4.7L 1981-83
  • Porsche 928S2 4.7L 1984-86

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

Its special limited-slip additives help reduce friction and prevent stick-slip behaviour, while maintaining a stable lubricating film under demanding operating conditions.

The SAE 85W-90 formulation provides reliable wear protection and lubrication across varying operating temperatures.

What Does It Do?

This gear oil lubricates and protects gears, bearings and differential components, reducing friction and wear while supporting smooth operation of compatible limited-slip differentials.

Why Does Gear Oil Deteriorate?

Common causes include:

  • High operating temperatures
  • Heavy mechanical loading
  • Contamination from internal wear
  • Moisture ingress Extended service intervals

When Should It Be Replaced?

Replace according to the vehicle manufacturer's service schedule or when the lubricant becomes contaminated or degraded. Unusual differential noise or limited-slip chatter may indicate a need for inspection.

Specifications & Recommendations

  • API GL5
  • MIL-L 2105 D
  • GM B 40 1010
  • Volvo 97311
  • ZF TE-ML 05C / 21C
  • DAF

The latter manufacturer specifications are LIQUI MOLY recommendations rather than formal approvals.

Porsche Compatibility & Installation

Suitable for Porsche differential or axle-drive applications only where the manufacturer specifies a compatible GL5 LS SAE 85W-90 lubricant.

Always confirm the correct specification, filling quantity and service interval before use. This oil is not a universal replacement for Porsche manual gearbox or PDK transmission fluids.

LIQUI MOLY Limited-Slip Differential Oils & Gear Lubricants

LIQUI MOLY Hypoid Gear Oil GL5 LS SAE 85W-90 is formulated for high-load axle drives with or without limited-slip differentials, particularly where LS additives are required.
