Engine wear shortens unit life, and repair or replacement is expensive. To help protect against it, Liqui Moly offers three agents: Oil Additive, Motor Protect and Cera Tec.
Oil Additive is ideal for older vehicles. It contains MoS2, a solid lubricant similar to graphite that reduces friction in the engine physically.
Motor Protect does the same, but chemically and with no solid lubricants. It is suited to state-of-the-art engines.
For newer vehicles, Cera Tec combines both strategies. It is effective for up to 50,000km.
