Lucas Oil Complete Fuel & Engine Treatment is a dual-purpose additive designed to clean, lubricate, and protect both the fuel system and engine oil. When added to fuel, it enhances combustion efficiency, removes deposits, and prevents ethanol-related corrosion, while in engine oil, it reduces friction, improves fluidity in cold starts, and extends oil life.Discover the key features of this advanced formulation:Fuel System Cleaning and Lubrication: Designed to clean and lubricate the entire fuel system from the tank to the injectors, this formulation removes carbon and deposit build-up from intake valves and combustion chambers, ensuring smoother engine operation and improved fuel atomisation.Corrosion Protection for Fuel System Components: Engineered to counteract the corrosive effects of ethanol-based fuels such as E5 and E10, this additive forms a protective barrier on metal components, reducing the risk of corrosion and prolonging fuel system longevity.Enhanced Combustion Efficiency
