How much do I need?

Just 10 ml of X-Carbon is required for every 50 litres of diesel or petrol, added straight into the fuel tank, every time you add more fuel. Cars’ fuel tanks can hold an average up to 45-70 litres depending on their make and model. ‍Like some advice? Please contact us.

I have never seen a reaction take place this quickly as with X-Carbon. I could hear the engine get quieter. I could feel it get smoother. I noticed that the throttle response had improved.
