Highly Efficient Carbon Deposit Cleaner: Designed specifically for diesel vehicles, it quickly breaks down and removes stubborn carbon deposits inside the engine, restoring fuel system cleanliness, improving combustion efficiency, and reducing power loss and idling jitter. Combustion-Assisted Energy Saving and Consumption Reduction: By optimizing the fuel molecular structure and promoting complete combustion, it effectively reduces fuel consumption by 10%-15%, while also reducing exhaust emissions (such as black smoke and particulate matter), meeting environmental protection requirements. Full System Protection: Covers key components such as injectors, cylinders, and piston rings, preventing carbon deposit regeneration, lubricating the fuel system, extending engine life, and reducing maintenance costs. Wide Compatibility: Suitable for all diesel vehicles (sedans, SUVs, trucks, etc.), China V and China VI diesel standards, and easy to add and mix directly into the fuel tank. Safe and Mild Formula: Formulated with non-corrosive chemicals and containing no metal components, it will not damage the engine or fuel lines over time.
