What is the carbon hydrogen ratio of petrol?

The carbon-to-hydrogen ratio of petrol (gasoline) typically ranges from about 1.5 to 1.8, depending on its exact composition. Petrol is primarily composed of hydrocarbons, with a general formula approximating CnH2n+2, where n represents the number of carbon atoms. This ratio indicates that for every carbon atom, there are approximately 1.5 to 1.8 hydrogen atoms in the fuel.
