This advanced formulation is specifically engineered to meet the rigorous demands of contemporary diesel engines, featuring specialized additives that provide superior protection against turbocharger deposits, soot contamination, and premature wear. The 5W-40 viscosity ensures optimal lubrication across all operating conditions, from cold starts to high-temperature driving, while maintaining excellent stability under demanding diesel operation. The package is enhanced withDiesel System Clean Plus 200ml, a highly concentrated fuel system cleaner specifically designed for modern diesel engines. This powerful additive effectively targets and eliminates carbon deposits, soot accumulation, and injector fouling that compromise performance and fuel economy. By thoroughly cleaning the entire fuel delivery system - including injectors, combustion chambers, and intake components - it restores optimal fuel atomization, enhances combustion efficiency, and helps maintain emission compliance while preventing power loss and restoring engine responsiveness.
