9.9 Simple to use

9.6 worth the money

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.

9.8 Simple to use

Why we love it

Clears turbo and EGR without dismantling.

Improves engine power and responsiveness.

Extends turbo and catalyst lifespan.
Main highlights

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.
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.
