Cera Tec engine oil additive is designed to reduce friction and component wear. Suitable for both diesel and gasoline engines, it contains ultra-fine ceramic particles that help form a protective coating and reduce friction between engine components. This minimizes wear and extends the engine’s lifespan. Additionally, the additive reduces fuel consumption and increases vehicle power by making energy use more efficient through friction reduction. This allows the engine to operate much more quietly. The additive is compatible with various motor oils and is completely safe. It can be easily added during a scheduled oil change.
