Why We Love It

Clears blocked diesel turbochargers efficiently.
Improves engine power significantly.
Extends turbo and catalyst life.

Main Highlights

✅ CLEARS BLOCKED DIESEL TURBOCHARGERS: Designed to effectively remove carbon build-up and free sticking vanes without the need for dismantling, this powerful formula ensures optimal performance of diesel turbochargers. Over time, carbon deposits accumulate on the turbine, leading to reduced efficiency and potential turbocharger failure. By dissolving these stubborn residues, the product restores proper airflow, allowing the turbo to function smoothly. The seamless operation of the turbocharger translates into improved acceleration, fuel efficiency, and overall vehicle performance.
✅ REMOVES RESIDUES FROM DIESEL OXIDATION CATALYST & CLEANS EGR VALVE: Residue buildup in the Diesel Oxidation Catalyst (DOC) and the Exhaust Gas Recirculation (EGR) valve can significantly impact engine efficiency and emissions. This advanced cleaning solution effectively dissolves deposits, ensuring these essential components remain free from obstructions. The DOC plays a crucial role in reducing harmful emissions, while the EGR valve helps control nitrogen oxide levels. When clogged with soot and carbon deposits, both systems become less effective, leading to increased fuel consumption and reduced engine efficiency.
✅ RE-ESTABLISHES ENGINE POWER & THROTTLE RESPONSE: A clogged turbocharger and EGR valve can severely hinder an engine’s performance, leading to sluggish acceleration and power loss. This specialised cleaning formula helps restore engine power by removing accumulated deposits that interfere with combustion efficiency. By ensuring optimal airflow and fuel combustion, the engine regains its responsiveness, delivering smooth acceleration and improved throttle control. This is particularly beneficial for diesel vehicles that experience performance deterioration due to carbon buildup.
✅ EXTENDS TURBO & DIESEL OXIDATION CATALYST LIFESPAN: The buildup of soot and carbon deposits can significantly shorten the lifespan of turbochargers and Diesel Oxidation Catalysts, leading to costly repairs or replacements. This treatment not only cleans but also helps protect these vital components, ensuring they remain in optimal working condition for an extended period. By maintaining cleaner turbo and DOC systems, it prevents premature wear and degradation, reducing the risk of expensive mechanical failures.
✅ COMPATIBLE WITH ALL DIESEL ENGINES & BIODIESEL UP TO B30: Designed for versatility, this cleaner is suitable for all diesel engines and compatible with diesel fuels, including biodiesel blends up to B30. It provides a hassle-free solution for maintaining turbocharger and engine cleanliness without requiring extensive mechanical intervention. Simply add the recommended dosage to the fuel tank for a thorough cleaning effect that works while driving. The formulation is safe for all after-treatment systems, ensuring it does not cause damage to components such as catalytic converters, diesel particulate filters, or EGR valves.

Why We Love It

Restores engine power efficiently.
Improves combustion.
Reduces harmful emissions.

Main Highlights

✅ CLEARS BLOCKED TURBOCHARGERS FOR OPTIMAL ENGINE PERFORMANCE: Effectively eliminates blockages in turbochargers, ensuring smooth and efficient engine operation. Accumulated carbon deposits and contaminants can significantly reduce turbo efficiency, leading to sluggish acceleration, increased fuel consumption, and potential mechanical failures. This advanced cleaning solution targets stubborn build-ups that restrict airflow, restoring optimal turbo function. Compatible with all diesel and biodiesel engines up to B30, it provides a thorough cleaning effect, ensuring the turbocharger operates at peak performance.
✅ FREES STICKING VANES OF THE VARIABLE TURBO FOR ENHANCED RESPONSE: Designed to clean and free sticking vanes in variable geometry turbochargers, allowing them to adjust properly and maintain consistent boost pressure. Sticking vanes often result in poor throttle response, reduced power output, and inefficient fuel combustion. This high-performance cleaner penetrates and dissolves stubborn deposits, restoring the full range of motion to the turbo’s vanes. By ensuring the proper function of the variable turbo, acceleration improves, turbo lag is minimised, and overall engine efficiency is enhanced.
✅ REMOVES DEPOSITS FROM THE DIESEL OXIDATION CATALYST (DOC) FOR CLEANER EMISSIONS: Effectively breaks down and eliminates oil residues and unburned fuel particles that accumulate in the DOC. Over time, these deposits can clog the catalyst, reducing its ability to convert harmful emissions into less toxic gases. A clean DOC enhances exhaust after-treatment efficiency, leading to lower emissions and improved environmental performance. By maintaining a cleaner exhaust system, diesel engines comply better with emission regulations, reducing black smoke and particulate matter.
✅ EFFECTIVE CLEANING OF THE EGR VALVE TO PREVENT PERFORMANCE ISSUES: Provides a powerful cleaning effect on the Exhaust Gas Recirculation (EGR) valve, ensuring smooth operation and preventing malfunctions. Carbon build-up in the EGR valve can lead to restricted airflow, engine hesitation, and increased fuel consumption. This specialised formula dissolves stubborn deposits, allowing the valve to function correctly and maintain the proper recirculation of exhaust gases. A clean EGR system contributes to lower combustion temperatures, reduced NOx emissions, and improved engine efficiency.
✅ IMPROVES COMBUSTION AND REDUCES HARMFUL SOOT EMISSIONS: Enhances the combustion process by eliminating excessive soot formation, leading to cleaner exhaust emissions and improved fuel efficiency. Soot build-up in the combustion chamber and exhaust system can cause increased wear on engine components, reduced power output, and higher maintenance costs. This advanced cleaner actively reduces soot accumulation, optimising fuel burn efficiency and promoting a cleaner-running engine. By lowering soot emissions, it contributes to reduced environmental impact while maintaining peak engine performance.
