The term 'Fuel Figure' is a reference to the octane rating of a fuel, which is a measure of its performance in an internal combustion engine. Octane is a hydrocarbon molecule with six carbon atoms and fourteen hydrogen atoms, and is used as a fuel in gasoline engines. The octane rating of a fuel is determined by its ability to resist pre-ignition and knocking, which can cause engine damage. A higher octane rating indicates a fuel that is more resistant to pre-ignition and knocking.
