Wynn's Pre-MOT Emission Test Fuel System Cleaner - Reduces CO, HC & Exhaust Smoke - Cleans Injectors & Improves Combustion - Treats Catalytic Converter & GPF - 325ml

Wynn's
Why we love it
  • Passes MOT emissions easily.
  • Boosts fuel efficiency.
  • Restores injector performance.
Main Highlights
  • ✅ REDUCES EXHAUST EMISSIONS TO HELP PASS YOUR MOT: Specially formulated to reduce harmful emissions, this treatment is ideal as a fast-acting solution before an MOT emissions test. By improving combustion efficiency and reducing the build-up of carbon residues within the fuel system, it significantly lowers levels of carbon monoxide (CO) and hydrocarbons (HC) in the exhaust gases. This helps vehicles meet stringent emission standards and comply with testing requirements. Whether used in older or newer vehicles, the formula addresses the key contributors to emissions test failures, such as excessive exhaust smoke and unburnt fuel particles.
  • ✅ ENHANCES ENGINE COMBUSTION AND PERFORMANCE: Developed with advanced combustion-improving agents, this treatment enhances the overall efficiency of the engine. By optimising the air-fuel mixture and promoting cleaner fuel burn, it boosts engine responsiveness and torque. The result is smoother acceleration, reduced engine knocking, and a more stable idle. This improved combustion process also aids in achieving better fuel atomisation, leading to improved power output and better throttle response. It supports the longevity of the engine by minimising internal friction and preventing the formation of carbon build-up that could impair performance over time.
  • ✅ CLEANS INJECTORS FOR RESTORED SPRAY PATTERN: This high-performance additive targets injector nozzles, removing gum, varnish, and carbon deposits that accumulate with regular fuel use. Clean injectors are crucial to maintaining a precise spray pattern, which ensures the correct atomisation of fuel and an efficient combustion cycle. Restoring the injector spray pattern leads to more effective fuel delivery, better combustion, and reduced emissions. Over time, dirty injectors can cause uneven idling, misfires, and loss of engine power.
  • ✅ TREATS THE ENTIRE FUEL SYSTEM INCLUDING CATALYTIC CONVERTER & GPF: Designed to work throughout the entire fuel system, this treatment not only cleans injectors but also reaches the catalytic converter and Gasoline Particulate Filter (GPF). It breaks down and removes harmful deposits that can block these critical components and lead to performance losses or emissions test failure. This comprehensive cleaning action helps maintain the flow and efficiency of the exhaust after-treatment system, allowing it to function properly.
  • ✅ IMPROVES FUEL ECONOMY AND REDUCES HARMFUL SMOKE: By enhancing combustion efficiency and ensuring clean injector operation, this formula directly contributes to fuel savings. Improved fuel atomisation results in more complete combustion of every drop of fuel, reducing waste and increasing mileage. Additionally, the product reduces exhaust smoke — particularly noticeable in older vehicles or those with accumulated carbon deposits. Cleaner combustion also means fewer unburned hydrocarbons are released into the atmosphere, making the vehicle more environmentally friendly.

Wynn's
Why we love it
  • Prevents irregular idling, jerking.
  • Improves fuel efficiency significantly.
  • Protects entire fuel system.
Main Highlights
  • ✅ THOROUGH CLEANING OF INJECTORS AND FUEL SYSTEM COMPONENTS: Effectively eliminates existing deposits in injectors and the fuel pump while ensuring that these vital engine components remain clean over time. This advanced cleaning action not only helps restore the optimal spray pattern of the injectors but also contributes to smoother engine performance. Built-up residues in the injectors, intake manifold, and combustion chamber are among the most common causes of reduced engine efficiency and increased emissions.
  • ✅ PREVENTS DEPOSIT FORMATION AND IMPROVES ENGINE DURABILITY: Acts as a powerful preventative treatment that stops the formation of harmful carbon deposits on intake valves, inside the manifold, and in the combustion chamber. These deposits can severely impact engine performance, leading to knocking, poor fuel economy, and increased exhaust emissions. By creating a protective environment within the fuel system, the product ensures long-term cleanliness and consistent fuel delivery. It is compatible with both leaded and unleaded petrol, making it versatile and reliable across a wide range of petrol engines.
  • ✅ SMOOTHER ACCELERATION, COLD START SUPPORT, AND STABLE IDLING: Provides a noticeable improvement in engine operation by preventing irregular idling and hesitation during acceleration. It is particularly effective in helping engines start more easily in cold conditions, reducing the strain typically associated with cold starts. The formula is designed to support steady and smooth acceleration by addressing jerking, knocking, and auto-ignition issues. These issues often arise from an unbalanced air-fuel mixture caused by dirty injectors or valve deposits.
  • ✅ LUBRICATION OF CRITICAL ENGINE PARTS FOR OPTIMAL COMBUSTION: This lubrication plays a significant role in reducing friction and wear, especially in high-stress areas that experience intense pressure and heat. By improving the internal lubrication of the engine’s fuel system, it helps to enhance combustion efficiency and reduce fuel consumption. Well-lubricated components operate more smoothly and are less prone to long-term damage, which supports extended engine life and consistent performance. The result is a more efficient engine that consumes less fuel and emits fewer pollutants.
  • ✅ PROTECTION AGAINST RUST, CORROSION, AND MOISTURE ACCUMULATION: Offers comprehensive protection for the entire fuel system by preventing rust and corrosion, especially in metallic components exposed to fluctuating temperatures and humidity. The product absorbs condensation and moisture that may accumulate in the fuel tank or lines, helping to avoid water-related damage that can compromise engine performance. This protective effect is especially valuable in environments where fuel quality may vary or where engines are not used frequently.
