Liqui Moly Cera Tec Ceramic Engine Protection Additive (300 ml)

Cera Tec is Liqui Moly's flagship friction and wear protection additive, built around a suspension of ceramic boron-nitride particles that bond to metal surfaces inside the engine. The result is a smoother, quieter, better-protected drivetrain that holds up under high load and high temperature.

One 300 ml bottle treats up to 5 litres of engine oil and stays effective for roughly 50,000 km, so a single dose covers most owners for a year or more of driving.

What it does

• Lays down a ceramic protective layer that reduces metal-to-metal friction and wear
• Resists extreme pressure and temperature, including momentary lubrication-loss conditions
• Lowers running friction, which can improve smoothness and fuel efficiency
• Chemically stable and miscible with all commercial mineral and synthetic motor oils

How to use

Add the full bottle to warm engine oil. One 300 ml bottle is dosed for up to 5 litres of oil. Best added at an oil change. Effective for approximately 50,000 km.
