Liqui Moly Cera Tec Ceramic Friction Modifier 6×300ml pack — reduces wear, smooths engines

Liqui Moly Cera Tec is a high-tech ceramic friction modifier that mixes into engine oil to reduce metal-on-metal contact, cut wear, and improve smoothness.

Engine components experience constant friction, heat, and stress; Cera Tec introduces ceramic-based additives that bond with metal surfaces to form a resilient, sliding layer. That layer lowers mechanical friction and helps preserve bearings, cams, pistons, transmissions and other moving parts without changing the oil chemistry. This listing is for a pack of six 300 ml bottles, each designed to treat up to 5 liters of oil.

How does Cera Tec protect moving parts inside engines and gearboxes?

Cera Tec contains thermally stable ceramic compounds that adhere to metal surfaces, creating a thin, wear-resistant film. This film prevents direct metal-to-metal contact and smooths surface irregularities, reducing abrasive and adhesive wear over time.

• Forms a ceramic-rich boundary layer on treated surfaces
• Reduces friction peaks during start-up and heavy load
• Compatible with petrol and diesel engine oils
• Also suitable for transmissions, pumps and compressors (not for wet clutches)

Will adding Cera Tec affect my oil or service intervals?

Cera Tec is formulated to be blended into the existing oil and does not require oil changes solely because of its use. It does not replace recommended oil change intervals; instead, it works alongside the oil to extend component life and can provide long-lasting effects between services.

• One 300 ml bottle treats up to 5 liters of oil
• Designed for long-term effect—up to 50,000 km under normal conditions
• No special mixing procedure—add directly to warm oil before or after fill

How should I use this 300 ml bottle and what vehicles are supported?

Use one 300 ml bottle per 5 liters of oil; pour it into the oil filler or timing cover area while the engine is warm so the product disperses evenly. It is safe for use with most commercially available engine and transmission oils, but it must not be used in systems with wet clutch packs where friction material interaction is required.

• Dosage: 300 ml per 5 L oil volume (adjust proportionally for different capacities)
• Suitable for petrol and diesel engines, plus gearboxes, pumps and compressors
• Not compatible with wet-clutch transmissions—avoid use in motorcycles with wet clutches

What performance benefits can I expect after treatment?

After treatment you can expect smoother operation and a reduction in friction-related noise and wear. While exact fuel savings vary with vehicle and driving conditions, smoother running often translates to modest efficiency gains and a quieter running characteristic.

• Reduces friction and wear at contact points
• May lower fuel consumption in petrol and diesel engines
• Helps extend the life of engine and transmission components

Who is this for? Liqui Moly Cera Tec 300 ml (pack of 6) is aimed at owners and technicians who want a proven ceramic-based friction modifier to protect engines, gearboxes, compressors and pumps. It’s particularly useful for regular drivers seeking to reduce long-term wear, fleet managers looking to extend component life, and enthusiasts who want quieter, smoother operation. Avoid use in wet-clutch systems and always follow vehicle manufacturer guidance when adding oil additives.
