Wynn's High Performance Diesel Fuel System Treatment - Enhances Combustion, Improves Acceleration, Reduces Fuel Consumption & Black Smoke - 500ml

Wynn's High Performance Diesel Fuel System Treatment - Enhances Combustion, Improves Acceleration, Reduces Fuel Consumption & Black Smoke - 500ml

Improves engine performance instantly.
Reduces fuel consumption effectively.
Protects against oxidation.

Main Highlights

✅ IMPROVES COMBUSTION FOR OPTIMAL ENGINE PERFORMANCE: This high-performance diesel treatment is formulated to enhance combustion efficiency immediately upon use. The powerful blend of active ingredients optimises the fuel-to-air ratio, allowing for a cleaner and more complete burn inside the engine. As a result, the engine runs more smoothly and efficiently, leading to improved throttle response and faster acceleration. Enhanced combustion also contributes to a reduction in harmful emissions and particulate matter, resulting in a cleaner exhaust. This makes it particularly effective for vehicles that operate under demanding conditions, where peak engine performance is essential.
✅ REDUCES FUEL CONSUMPTION FOR COST-EFFICIENT DRIVING: By promoting more complete combustion, this treatment directly contributes to a reduction in fuel consumption. It maximises the energy extracted from each litre of diesel, helping the engine to deliver better mileage without compromising performance. Whether used in long-distance driving or frequent short trips, this product supports fuel efficiency by optimising the way diesel is burned. The result is lower fuel costs over time and less frequent refuelling. Regular application helps maintain this improved fuel economy, making it a smart choice for fuel-conscious drivers and fleet operators alike.
✅ REDUCES BLACK SMOKE FOR CLEANER EMISSIONS: This advanced diesel system treatment addresses one of the most visible signs of inefficient fuel use: black smoke. By improving the combustion process, the treatment drastically reduces unburned hydrocarbons that manifest as dark exhaust. This contributes not only to a cleaner vehicle but also to a more environmentally friendly operation. Vehicles treated with this formula emit noticeably less smoke, which can be a critical factor in passing emission tests or complying with urban environmental regulations.
✅ PROTECTS THE FUEL SYSTEM FROM OXIDATION AND CORROSION: The formula includes special additives designed to shield the fuel system from the damaging effects of oxidation and corrosion. Diesel engines are particularly susceptible to water contamination and fuel degradation, which can lead to rust, corrosion, and the formation of sludge within the fuel tank and injection system. This treatment provides a protective barrier that inhibits these processes, extending the lifespan of fuel components such as injectors, pumps, and lines. It is especially beneficial in vehicles that are not used regularly, where stagnant diesel may pose a greater risk.
✅ TREATS UP TO 70 LITRES WITH ONE 500ML BOTTLE: The concentrated nature of this formula ensures that a single 500ml bottle is sufficient to treat up to 70 litres of diesel fuel. This high-yield ratio makes it a cost-effective solution for those looking to maintain peak engine performance without frequent applications. Suitable for cars, vans, trucks, and other diesel-powered machinery, this treatment integrates seamlessly into routine maintenance schedules. Its easy-to-use format allows it to be poured directly into the fuel tank, ensuring fast action and visible results.
