Features

INJECTION SYSTEM CLEANING & PROTECTION A clean fuel system is essential for maintaining vehicle performance and efficiency. Wynn's Formula Gold Petrol System Treatment actively cleans and protects the entire fuel injection system, preventing deposits from forming on critical components such as injectors, intake valves, and combustion chambers. A well-maintained injection system allows for smoother fuel delivery, preventing engine hesitation and misfires. By continuously safeguarding these components, the treatment ensures that the vehicle maintains optimal power output while extending the life of the fuel system.
FUEL EFFICIENCY & CONSUMPTION REDUCTION This advanced formula actively works to lower petrol consumption by optimising the fuel system's efficiency. By cleaning and maintaining fuel injectors, the treatment ensures a precise air-fuel mixture, which directly leads to improved mileage and reduced fuel wastage. The result is a more cost-effective driving experience with fewer trips to the petrol pumps. Over time, continuous use helps prevent build-up in the injection system, allowing the engine to operate with maximum efficiency, reducing the strain on fuel components and prolonging their lifespan.
REDUCTION OF HARMFUL EMISSIONS Designed to contribute to a cleaner environment, this treatment significantly reduces harmful exhaust emissions such as carbon monoxide (CO) and hydrocarbons (HC). By promoting more complete combustion, the formula helps decrease the production of toxic gases, making it an ideal solution for those aiming to meet stringent emissions regulations. Regular use can assist in passing MOT emissions tests by lowering pollution levels and ensuring the engine operates within regulatory standards. A cleaner exhaust system means less impact on the environment and improved air quality.
SAFE FOR CATALYTIC CONVERTERS & ALL PETROL ENGINES Wynn's Formula Gold Petrol System Treatment is formulated to be completely safe for use in all petrol engines, including those equipped with catalytic converters and modern exhaust after-treatment systems. Unlike harsh additives that can damage sensitive engine components, this treatment is carefully engineered to enhance performance without causing harm. Suitable for both older and newer vehicles, it provides a versatile solution for maintaining engine efficiency. For optimal performance, it is recommended to use this treatment in every third tank of fuel to continuously benefit from its cleaning and protective properties.
