3. Product Description
The FACOM 006025 Integral Diesel Engine Decarbonizer is a high-performance catalytic detergent designed for comprehensive cleaning of diesel engine systems. It targets and cleans critical components such as valves, combustion chambers, EGR valve, turbocharger, catalytic converter, and diesel particulate filter (DPF) without requiring disassembly. It also thoroughly cleans the entire fuel supply system, including the injection pump and injectors.
This curative treatment helps to restore optimal engine performance, reduce harmful emissions, and decrease fuel consumption. It is particularly effective in facilitating vehicle compliance with technical inspection standards. The product begins to show effectiveness after driving 50 to 100 km, ideally at high engine speeds on a highway.

4. Usage Instructions
For optimal results, follow these instructions carefully:
- Frequency: This treatment is recommended every 20,000 to 30,000 km, or specifically before a technical inspection.
- Preparation: Shake the bottle well before use.
- Application: Pour the entire 1-liter dose into the fuel tank just before filling up with diesel. This ensures proper mixing with the fuel.
- Compatibility: The product is compatible with all Diesel injection systems (Common Rail, pump injectors) and all anti-pollution systems.
- Driving Conditions: After adding the product and refueling, drive for 50 to 100 km, ideally on a highway at high engine speeds. This allows the additive to work effectively under pressure and heat, cleaning the targeted components.

5. Maintenance
Regular use of FACOM 006025 as per the recommended frequency (every 20,000 to 30,000 km) helps maintain engine cleanliness and prevent carbon buildup. This proactive maintenance can extend the life of critical engine components and ensure consistent performance.
6. Troubleshooting
This product is designed to address common issues related to carbon buildup in diesel engines. If you experience any of the following, FACOM 006025 may help:
- Reduced Engine Performance: If your vehicle experiences power loss, rough idling, or sluggish acceleration, carbon deposits might be the cause. This product helps clean these deposits to restore performance.
- Increased Fuel Consumption: An unclean engine can lead to inefficient fuel burning. By cleaning the fuel system and combustion chambers, this additive can help improve fuel economy.
- Excessive Exhaust Smoke: Black or excessive smoke from the exhaust can indicate carbon buildup in the engine or DPF. The decarbonizer assists in cleaning these systems, reducing smoke.
- Technical Inspection (CT) Issues: If your vehicle fails or is at risk of failing emissions tests due to high pollutant levels, using this product before the inspection can significantly improve results.
- Engine Warning Lights (e.g., DPF, EGR): While not a guaranteed fix for all mechanical failures, many users have reported that using this product helped clear DPF or EGR related warning lights by cleaning the affected components.
If issues persist after following the usage instructions, it is recommended to consult a qualified automotive mechanic for further diagnosis and repair.
