Tec4 Premium Diesel System Cleaner is a multi-action, professional-grade fuel system treatment engineered to provide comprehensive cleaning and protection for modern diesel engines. Formulated to combat internal diesel injector deposits (IDIDs), carbon crusting, and fuel oxidation, it restores lost engine power, sharpens throttle response, and maximizes fuel efficiency.

Designed for compatibility with advanced emission control systems, Tec4 Premium Diesel System Cleaner neutralizes harmful moisture in the fuel tank, protects high-pressure pumps with added lubricity chemistry, and aids passive regeneration of the Diesel Particulate Filter (DPF).

Key Performance Benefits

• Comprehensive Fuel System Cleanup: Removes carbon deposits, gum, and lacquer from fuel injectors, combustion chambers, and high-pressure supply lines.
• Restores Power & Mileage: Cleans restricted fuel injectors to restore original spray patterns, recovering lost horsepower, torque, and fuel economy.
• Supports DPF Regeneration: Promotes cleaner, more complete combustion to reduce soot formation and assist the Diesel Particulate Filter (DPF) in staying clean.
• High-Pressure Lubricity Guard: Adds extra lubricity to low-sulphur diesel (ULSD) and biodiesel blends to prevent excessive pump and injector wear.
• Water Emulsification & Corrosion Defense: Traps and safely removes condensation from the fuel tank, preventing corrosion, bacterial growth, and filter clogging.
• Smoother Idling & Easy Cold Starts: Restores balanced fuel distribution across all cylinders, reducing diesel knock, smoke emissions, and engine hesitation.
