Long-term flushing ATOMIUM APROHIM™ is designed to clean the internal surfaces of the engine from long-standing deposits, removes black sludge and other contaminants and deposits. Flushing belongs to the class of "soft" cleaners, which require a certain time of action. This is why flushing must be added to the oil system approximately 200 kilometres before the planned oil change. This mileage and, consequently, engine hours will be sufficient for effective, but at the same time gradual, safe cleaning. Engine flush - consistently dissolves contamination by the incoming flow of oil, does not allow the formation of lumps and clots suspended in the oil.
