ML203 is a reinforced formula designed for fast and efficient cleaning of pistons, compression and oil control rings from stubborn resinous-coke and soot deposits of heavy-duty trucks and large special and agricultural machinery. It eliminates high oil consumption and levels compression in the cylinders, restoring engine power characteristics. Suitable for high mileage vehicles. • High penetrating ability • Decokes compression and oil control rings • Restores compression deviation from norm by 20-25% • Fights long-standing oil carbonization and fuel consumption issues • Action time from 30 to 60 minutes • Pack sizes are designed for engines up to 12.0 L • Does not require removing the oil pan • The procedure is carried out with mandatory oil change
