The temperature at which petrol oil solidifies, or the pour point, ranges between 90 degrees Fahrenheit to negative 70 degrees Fahrenheit. Petrol does not have just one freezing point.
Petrol is made up of several key compounds, including hydrocarbons, hydrogen, oxygen and some traces of metal. Each component reacts differently when exposed to lower temperature: lighter components may turn to gas, while heavier components turn thick in room temperature.
Most types of petrol derivatives do not crystallize in cold temperature but become much more viscous. The colder the petrol gets, the more it becomes sluggish and thick as tar or molasses. In lower temperatures, however, the petrol may reach its pour point, a certain temperature where petrol does not flow and adapts the viscosity of plastic.
