Decoking of the ML203 NOVATOR engine is a reinforced composition for quick and effective cleaning of pistons, compression and oil rings from persistent tar-coke and carbon deposits. Thanks to its high penetrating ability, ML203 softens and removes dirt in one hour. As a result, oil consumption is normalized, compression in the cylinders is equalized, and the traction and speed characteristics of the engine are restored. Suitable for all types of gasoline and diesel engines, including high mileage vehicles.
