Why we love it

Restores engine performance efficiently.

Improves fuel economy noticeably.

Reduces harmful emissions effectively.
Main highlights

RESTORES LOST ENGINE PERFORMANCE & REDUCES EMISSIONS: The Extreme diesel system cleaner revitalises the engine power by cleaning and protecting critical fuel system components. Improves throttle response, acceleration, and overall drivability by ensuring an uninterrupted fuel supply. Reduces harmful exhaust emissions by promoting cleaner combustion and minimising unburned fuel residues. Helps the engine run more smoothly and quietly, reducing vibrations and improving overall efficiency. Supports compliance with emission standards by lowering carbon monoxide, nitrogen oxides, and particulate matter in exhaust gases.
RESTORES FUEL ECONOMY: This product helps optimise fuel consumption by ensuring a cleaner and more efficient fuel-burning process. By eliminating harmful deposits and improving fuel atomisation, it contributes to a smoother and more complete combustion cycle. This results in less fuel waste and improved miles per gallon, allowing for greater cost savings over time. By restoring lost performance, the cleaner enables engines to operate at peak efficiency, reducing unnecessary fuel consumption caused by inefficient combustion. Ideal for vehicles experiencing a decline in fuel economy due to carbon build-up and fuel injector blockages.
PREVENTS PROBLEMS WITH TURBO, EGR VALVE & DPF: Designed to maintain the cleanliness of crucial engine components such as the turbocharger, Exhaust Gas Recirculation (EGR) valve, and Diesel Particulate Filter (DPF). Helps prevent carbon and soot build-up, which can lead to blockages and reduced performance. By keeping these components clean, it enhances engine efficiency and reduces the risk of costly repairs. Supports proper airflow and exhaust circulation, ensuring smooth turbo operation and reducing emissions. Helps to minimise common diesel engine issues such as sluggish acceleration, excessive smoke, and reduced power caused by carbon deposits.
ELIMINATES AND AVOIDS STARTING PROBLEMS: Effectively addresses hard starting issues caused by contaminated fuel or clogged injectors. Ensures a smoother ignition process by restoring proper fuel flow and combustion efficiency. Helps eliminate rough idling, misfires, and hesitation that often result from a dirty fuel system. By cleaning the fuel injectors and fuel pump, it improves cold starts and reduces strain on the battery and starter motor. Ideal for vehicles that experience difficulties starting due to carbon deposits and injector blockages. Consistent use helps prevent future starting problems and maintains reliable engine operation under various driving conditions.
CLEANS THE ENTIRE DIESEL FUEL SYSTEM: Effectively removes dirt, carbon deposits, and other harmful residues that accumulate within the fuel system over time. Ensures a cleaner and more efficient combustion process by thoroughly cleaning key components such as the fuel pump, diesel injectors, and intake valves. By dissolving stubborn contaminants, it helps prevent clogging and improves the overall efficiency of the fuel delivery system. Designed to work in a single treatment, providing a powerful 'one tank' clean-up that restores optimal fuel system functionality.

9.9 Simple to use

9.4 worth the money

9.3 distance

Why we love it

Restores engine power efficiently.

Reduces harmful emissions significantly.

Cleans turbochargers effectively.
Main highlights

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.
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.
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.
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.
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.
