Its glycol ether-based formulation offers high wet and dry boiling points, excellent low-temperature flow characteristics and protection against corrosion and oxidation.

Vehicle Compatibility

Suitable for electric, hybrid and conventional vehicles requiring brake fluid that meets the product's stated specifications.

For Porsche applications, including electric and hybrid models, always confirm the manufacturer's prescribed brake fluid specification before use.

What Does It Do?

DOT 5.1 EV brake fluid transfers hydraulic pressure through the braking system, allowing the brakes to operate effectively.

Its low viscosity supports fast hydraulic response in modern ABS and ESP systems, while low electrical conductivity makes it particularly suitable for electric vehicle applications.

Why Does Brake Fluid Deteriorate?

Common causes include:

  • Moisture absorption over time
  • Repeated exposure to high braking temperatures
  • Contamination during servicing
  • Oxidation and ageing
  • Reduced boiling point as moisture content increases

When Should It Be Replaced?

Replace brake fluid according to the vehicle manufacturer's service schedule.

Earlier replacement may be necessary if moisture content is excessive, the fluid is contaminated or the braking system has undergone repairs.

Checks & Application

Check the vehicle's required brake fluid specification before use.

Suitable for conventional brake bleeding equipment. LIQUI MOLY recommends using the product on its own for optimum performance and following the vehicle manufacturer's replacement intervals.

Key Features

  • Synthetic glycol ether-based DOT 5.1 EV brake fluid
  • Low electrical conductivity
  • High wet and dry boiling points
  • Excellent low-temperature viscosity
  • Suitable for compatible ABS and ESP systems
  • Corrosion and oxidation protection
  • Good compatibility with hydraulic system elastomers
  • Suitable for compatible brake and clutch systems
  • 500ml container

Specifications & Approvals

  • FMVSS 116 DOT 3, DOT 4, DOT 4 LV, DOT 5.1 and DOT 5.1 LV.
  • ISO 4925 Classes 3, 4, 5.1, 6 and 7.
  • SAE J1703 / J1704.

LIQUI MOLY DOT 5.1 EV Brake Fluid for Electric, Hybrid & Porsche Vehicles

Modern electric, hybrid and conventional braking systems require brake fluids that maintain reliable hydraulic pressure, thermal stability and compatibility with advanced braking technology.

LIQUI MOLY DOT 5.1 EV combines low electrical conductivity, high boiling points and excellent cold-temperature performance, making it suitable for vehicles requiring its specified brake fluid standards.

Design911 offers LIQUI MOLY brake fluids and vehicle maintenance products for compatible Porsche applications.

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

LIQUI MOLY Cera Tec Engine Oil Additives for Porsche

LIQUI MOLY Cera Tec provides additional ceramic-based wear protection for compatible Porsche petrol and diesel engines, including classic air-cooled 911 models and modern water-cooled applications.

Its combination of ceramic particles and friction modifiers helps reduce mechanical friction, improve smooth running and protect engine components under demanding operating conditions.

Design911 supplies LIQUI MOLY engine oil additives, lubricants and maintenance products for classic and modern Porsche vehicles.
