The core of this package features RACING DEVELOPMENT TRD SPORT 5W30 100% Full-Synthetic Engine Oil, a high-performance lubricant developed with racing technology for modern diesel engines. This advanced full-synthetic formulation provides outstanding protection against soot contamination, turbocharger deposits, and wear, ensuring your diesel engine maintains peak performance under demanding conditions. The 5W30 viscosity guarantees quick cold-start protection and optimal lubrication across all temperature ranges, while its sophisticated additive package controls deposits and maintains engine cleanliness for enhanced efficiency and longevity. Complementing this superior lubrication is Diesel System Clean Plus 200ml, a concentrated fuel system treatment specifically designed for modern diesel engines. This powerful cleaner effectively targets and removes carbon deposits, soot accumulation, and injector fouling that can compromise diesel engine 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.
