The technique of establishing the octane number of motor gasoline is costly and time-consuming, and it requires the use of a testing engine, which may not be accessible in small or remote labs. Using connections between the octane number of motor gasoline and its physical and chemical properties, simple and useful formulae for computing an octane index using gasoline qualities that are easily and frequently checked were created. Gasoline density, boiling temperatures, characterization factor, and cyclic chemicals concentration are all considered. The equation resulting from the octane index and characterisation factor correlation in particular makes calculating the combustion properties of most commercially available gasoline simple and precise.
