Fast-acting product designed to clean stuck piston rings of gasoline and diesel engines from carbon. Application is recommended after engine overheating, by increased oil consumption and smoking.

• Restores mobility of stuck piston rings.
• Decreases oil consumption.
• Cleans cylinders and pistons, combustion chambers, and valves from all types of contaminations (scale, carbon, varnish and tar).
• Restores compression in cylinders.
• Decreases exhaust toxicity.

1. Warm up the engine. The engine should be warm but not hot.
2. Unscrew the plugs (nozzles). Disconnect the wire of the ignition timing sensor, Hall sensor or commutator.
3. Introduce approximately 60 ml of product (1/4 of the bottle) into each cylinder through the plug hole.
4. 1 bottle (250 ml) is enough to decarbonize 4 cylinders. Screw the plugs back.
5. Wait for 60 minutes. Unscrew the plugs. Cover the plugholes with absorbing fabric to avoid dirt flying out and getting onto the paint.
6. Rotate the engine with the starter for several seconds.
7. Reinstall spark plugs (nozzles).
8. Start the engine and run it at variable RPM for up to 15 minutes. During this time, the residues of the softened carbon will be removed through the exhaust system.
9. Change the motor oil.

Avoid getting the substance onto the paint.

Safe for catalytic converters, oxygen sensors, mechanical rubber goods and seals.
