Petrol is made of a mix of alkanes and cycloalkanes with a chain length of between 5-12 carbon atoms. These boil between 40°C and 205°C. Gas oil or Diesel is made alkanes containing 12 or more carbon atoms. These have a boiling point between 250°C and 350°C.
What is mean by petrol and diesel?

Which is faster diesel or petrol?
Though the diesel variant has a higher torque than the petrol, it does so on a lower rpm due to which shifting is necessary sooner than that on the petrol. Thus the petrol produces more power and accelerates from 0 to 100 quicker.
