Liqui Moly Common Rail Additive is a high-performance diesel fuel additive specially developed for modern common rail and pump-injection diesel engines. It contains a powerful combination of cleaning agents and lubrication improvers designed to protect high-pressure injection systems running on low-sulphur diesel fuel. This advanced formulation ensures optimum lubrication of sensitive injection components, helping to prevent wear, seizing, and injector gumming. The additive also improves combustion efficiency, particularly during cold starts, resulting in smoother engine operation, reduced exhaust odour, and lower fuel consumption. By keeping the entire fuel system clean and protected, Liqui Moly Common Rail Additive helps restore engine performance, improve fuel economy, and extend the service life of critical diesel components.
