Wynn's Diesel Turbo Cleaner – Diesel Power Restorer

Wynn’s Diesel Turbo Cleaner is a 500ml formula specifically designed for diesel engines. It effectively removes carbon build-up from turbochargers, freeing sticking vanes without dismantling. The cleaner also targets residues in the Diesel Oxidation Catalyst (DOC) and the EGR valve, helping to restore engine power and throttle response.

By reducing soot emissions and extending the lifespan of your turbo and DOC, this additive offers a comprehensive cleaning solution. It’s particularly useful if you’ve noticed sluggish acceleration or power loss in your diesel vehicle. Simply add it to the fuel system as directed, and it works while you drive.

View all product features

• ✅ 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.

Buyer’s Guide: What to Consider

Choosing the right EGR valve cleaner additive depends on your engine type and the specific deposits you need to remove. Here are the key factors to consider.

• Engine Compatibility: Ensure the cleaner is formulated for your engine type—gasoline, diesel, or hybrid—to avoid damage and ensure effectiveness.
• Comprehensive Cleaning: Look for cleaners that target not just the EGR valve but also related components like turbochargers, catalytic converters, and O2 sensors for a thorough clean.
• Application Method: Choose between fuel additives you pour into the tank or intake system sprays. Fuel additives are easier, while sprays may offer more direct cleaning.
• Check Engine Light Codes: Check if the product can help clear specific check engine codes like P0420 or P0430, which indicate emissions system issues.
• Treatment Duration: Consider the treatment time and how long it takes to see results. Some products work in under an hour, while others require a full tank of fuel.
