Advantages of Petrol:
  • Though there is rapid rise in cost of petroleum, it is still cheaper than any other fuel.
  • Petrol has higher density than any other energy form of energy.
  • It is relatively safe of store, carry and dispense.
  • Petrol is obtained from distillation process which is not difficult to make.
  • The process of production of petrol does not need rare materials and the process does not involve letting out byproducts that are dangerous to the environment.
  • Petrol makes an excellent source of organic molecules which can be used for building plastics, fiber, medicines, etc.
  • Petrol can withstand high heats without breakdown and it makes useful lubricants like engine oil and grease.

  • There are many wars fought over oil and it is having a negative influence on relations between nations.
  • Transport of petrol is dangerous.
  • Oil spills during extraction of crude oil or transportation have catastrophic effects on the affected areas.
  • Crude oil producing areas are at chances of having severe weather conditions.
  • Petrol contains some cancer causing compounds like benzene.
  • The volatile components of petrol cause smog.
