This advanced fuel additive has been developed specifically to noticeably improve acceleration in the partial load range
For all diesel engines with and without diesel particle filters. Tested for turbo and catalytic converters Completely compatible with all conventional diesel and bio-diesel fuels. Excellent for continuous use at each refueling
Provides more driving pleasure through optimized performance yield
This highly modern fuel additive was specially developed to noticeably improve acceleration under partial load
✅ IMPROVES COMBUSTION FOR BETTER PERFORMANCE AND ACCELERATION: Designed to immediately enhance combustion, this high-performance diesel fuel system treatment improves the way in which fuel burns inside the engine. By promoting a more complete and efficient combustion process, it leads to improved throttle response and smoother acceleration. This results in a more dynamic driving experience, reducing hesitation and engine lag. Additionally, a more efficient burn reduces engine noise, making diesel engines operate more quietly and smoothly
✅ REDUCES FUEL CONSUMPTION FOR COST-EFFECTIVE DRIVING: By ensuring a cleaner and more efficient fuel system, this treatment helps lower fuel consumption. Deposits and impurities inside the fuel injectors can hinder proper fuel atomisation, leading to increased fuel usage. This advanced formula dissolves and prevents these deposits, allowing the engine to run at optimal efficiency, which translates into noticeable fuel savings. For frequent drivers or those looking to maximise fuel economy, this treatment provides a practical and effective solution to get the most mileage out of every tank.
✅ LOWERS HARMFUL EMISSIONS FOR A CLEANER EXHAUST SYSTEM: Designed to actively reduce carbon monoxide (CO) and hydrocarbon (HC) emissions, this diesel treatment contributes to cleaner exhaust gases. By promoting a more complete fuel burn, it significantly lowers unburned fuel residues that are released into the environment. This makes it particularly beneficial for vehicles undergoing emission testing or MOT inspections, helping engines comply with stricter environmental standards. The reduction of black smoke is another key advantage, improving air quality and making diesel engines more eco-friendly.
✅ CLEANS AND PROTECTS THE FUEL INJECTION SYSTEM FOR LONG-TERM ENGINE HEALTH: A clean fuel system is essential for optimal engine performance. This diesel fuel system treatment thoroughly cleans fuel injectors, preventing clogging and removing deposits that can lead to inefficiencies. By maintaining a clean injection system, fuel delivery is more precise, ensuring proper combustion and reducing engine wear. Additionally, the protective formula helps shield the fuel system from oxidation and corrosion, prolonging the lifespan of critical components.
✅ SAFE FOR ALL DIESEL ENGINES AND AFTER-TREATMENT SYSTEMS: Formulated to be completely safe for all modern and older diesel engines, this treatment is compatible with common-rail and direct-injection diesel systems. It does not harm after-treatment systems such as diesel particulate filters (DPF) or catalytic converters. The anti-corrosion properties help prevent rust and deposit buildup in the fuel system, ensuring long-term engine health. For best results, it is recommended to use this additive in every third tank of fuel.
