Liqui Moly Cera Tec Friction Modifier

Cera Tec is a ceramic-particle-suspension concentrate added to engine oil at each oil change · the brand states the ceramic compounds form a protective layer on metal surfaces to reduce friction and wear. The active ingredient is entirely proprietary: the SDS discloses no chemical substances. Pour one 300 ml bottle into 5 L of engine oil; the product is self-mixing. The manufacturer claims protection up to 50,000 km. A large owner community across petrol and diesel engines consistently reports reduced valve noise and smoother idle, spanning models from European turbodiesels to American V8s and European diesel sedans. No independent laboratory data · tribology, dyno, or peer-reviewed study · for this product's specific ceramic mechanism is publicly available. The performance evidence is community-reported, not instrument-confirmed.

Owners of modern 4-stroke petrol or diesel engines wanting a low-risk supplement · the manufacturer explicitly positions Cera Tec as safe for catalytic converters, DPFs, and hybrid stop-start systems with no phosphorus pathway concern. Reasonable for owners of aging or noisy engines whose consistent reports of noise reduction span a wide vehicle range. Skip it for wet-clutch applications (DSG, DCT, automatic transmissions, wet-clutch differentials) · explicitly ruled out by the manufacturer. Also skip if you need a product with published independent wear-reduction data: for that, a ZDDP supplement with disclosed active chemistry and a clear phosphorus calculation is a better-evidenced choice.

The SDS classifies this mixture as not dangerous under CLP/GHS (no signal word, no GHS pictograms, no H-codes at the mixture level). SDS §8 lists protective goggles, nitrile or neoprene gloves, and an A2/P2 filter for oil-mist conditions as precautionary measures without supporting H-code classifications · typical boilerplate for a petroleum-based lubricant. The US listing carries a Prop 65 warning; the specific substance is not identified in the EU-format SDS. Drain used engine oil to a used-oil collection facility, not the drain · petroleum-carrier oil additives follow the same used-oil disposal pathway as motor oil.
