Cleaners & Additives, found within our Lubricants & Fluids section, are essential for maintaining optimal vehicle performance and longevity in passenger cars and commercial vehicles. These products encompass a range of solutions designed to clean critical engine and vehicle systems, and enhance the properties of existing fluids. Fuel system cleaners remove deposits from injectors and valves, improving combustion efficiency and reducing emissions. Oil system additives can help restore compression, reduce oil consumption, and prevent sludge buildup. Coolant system cleaners flush out scale and corrosion, preventing overheating and damage to the radiator and water pump. Examples include Febi fuel system cleaner (MPN FEBI23932), Febi oil system additive (MPN 29449), and Volvo Trucks coolant flush (MPN VOE1161251).
