X‑Carbon when added to a tank of fuel, reduces the voltage generated in flowing fuel, cutting static electricity, reducing surface tension and cavitation (air retention / “vapour-lock”), helping to release the entrained air, making it more energy dense so it combusts more completely and consistently.
The lowering of surface tension also improves fuel droplet dispersion. Air release increases the fuel’s lubricity and viscosity, reducing metal on metal contact and damage and makes it a better solvent, cleaning carbon deposits from the inside of the engine.
