## Description

This diesel injector cleaner offers a powerful and complete solution for maintaining and restoring the efficiency of diesel engines. Engineered with high-performance cleaning agents, it targets the entire fuel system—from injectors and fuel pumps to the combustion chamber—removing carbon deposits, varnish, and other contaminants that accumulate over time. These residues can significantly degrade injector spray patterns, reduce combustion efficiency, and lead to increased fuel consumption and emissions. By eliminating such build-ups, this cleaner restores optimal injector function, ensuring precise fuel atomisation and a more complete and efficient burn. Not only does it clean, but it also improves the ignition quality of diesel fuel. This enhancement results in smoother engine operation, more reliable starts, and a noticeable reduction in diesel knocking noises. Enhanced combustion performance also leads to lower black exhaust smoke emissions, supporting cleaner air and improved engine compliance with modern emission standards. Additionally, the formulation includes lubricating properties that protect critical components like injectors and the fuel pump from premature wear and tear, extending their service life and maintaining smooth fuel delivery. Safe for use with all modern diesel after-treatment systems—including EGR, Turbo, DPF, and SCR—this product is compatible with even the most advanced diesel engines without compromising sensitive components. It offers dependable results without the use of metallic or abrasive compounds, making it a smart choice for long-term engine care. Designed for regular maintenance, it ensures engines remain efficient, powerful, and less prone to costly fuel system repairs or performance losses.

### ⭐⭐⭐⭐ Essential Fix for Knocking and Black Smoke
*by B***T on 12 October 2025*

For any driver of a modern or high-mileage diesel vehicle, injector cleaner is not a luxury—it's a maintenance necessity. The Wynn's Diesel Injector Cleaner is an incredibly effective, non-invasive solution that delivers noticeable, immediate results in smoothing out a rough diesel engine. It's the perfect pre-MOT treatment and a smart way to maintain fuel efficiency. Problem Solver: Immediate Noise and Smoke Reduction The primary benefits of this cleaner are instantly apparent and directly address the two biggest concerns for diesel owners: noise and emissions. Reduced Diesel Knock: After adding the full bottle to a nearly empty tank before a complete fill-up (treating roughly 60 litres), the difference in engine sound was significant. The characteristic harsh "rattle" or metallic knock at idle, common in cold starts, was noticeably muted within about 50 miles of driving. The engine idled much smoother and quieter. Black Smoke Elimination: Vehicles with higher mileage often generate a puff of black smoke during hard acceleration, indicating poor combustion and particulate buildup. This cleaner worked remarkably well to reduce this visible smoke, ensuring cleaner combustion and less buildup on the DPF (Diesel Particulate Filter) over time. Technical Insight and Value This product utilizes potent detergent chemistry to clean microscopic carbon and unburnt fuel deposits from the injector nozzles. By restoring the original fine spray pattern, it ensures every drop of fuel is combusted properly. Improved Efficiency: Cleaner injectors mean better fuel atomization, translating directly to improved torque response and a small, but measurable, boost in fuel economy. It essentially restores the engine’s performance closer to factory specs. Easy Application: The bottle is easy to open and dispense without spillage, which is a small but important detail. The 325ml size is perfectly matched to treat a standard 50-70 litre diesel tank, simplifying dosage. Consideration While the initial effects are excellent, the benefits are most dramatic on older engines or vehicles that have never used a cleaner before. For ongoing maintenance, a regular dose every 3,000 to 5,000 miles is highly recommended to prevent deposit buildup from recurring. The Verdict The Wynn's Diesel Injector Cleaner is a phenomenal, cost-effective maintenance item that punches above its weight. It is essential for passing emissions tests and provides tangible improvements in engine refinement and noise levels. It’s a crucial tool for keeping your diesel running cleanly and efficiently—an absolute must-buy for any diesel driver.
