Petroleum must be separated into fractions by the method of boiling to use it efficiently.

Some commercial uses of various petroleum fractions are shown in the table below.

Petroleum Fraction in Terms of Numbers of Carbon Atoms	Major Uses
${\text{C}}_{\text{5}}-{\text{C}}_{\text{10}}$	Gasoline
${\text{C}}_{\text{10}}-{\text{C}}_{\text{18}}$	Kerosene Jet fuel
${\text{C}}_{\text{15}}-{\text{C}}_{\text{25}}$	Diesel fuel Heating oil Lubricating oil
${\text{>C}}_{\text{25}}$	Asphalt

Conclusion

Use of petroleum fractions are gasoline, kerosene, diesel and jet fuel, heating and lubricating oil etc.
