HKS Direct Sludge Remover (400ml)

HKS Direct Sludge Remover Specifications

HKS Direct Sludge Remover (DSR) is an engine cleaning additive specially developed to effectively eliminate sludge, varnish, and deposits accumulated in the lubrication circuit. Used before an oil change, it acts quickly inside the engine to dissolve contaminants that can impair performance and accelerate mechanical component wear.

Its advanced formulation cleans oil passages, piston rings, and various internal engine surfaces without the need for disassembly. By promoting the evacuation of deposits during the oil change, DSR helps restore the efficiency of the lubrication system and preserve engine performance over the long term.

Compatible with gasoline and diesel engines, excluding 2-stroke and rotary engines, HKS Direct Sludge Remover is a simple and effective solution for preparing the engine before replacing the oil, particularly for preventive maintenance or after intensive use. One 400 ml bottle is suitable for 3 to 6 liters of oil.
