Difference between Petrol and Diesel

There is a big difference between petrol and diesel engines. Petrol engines are more common, but diesel engines are becoming more popular. Here we will discuss the differences between these two types of engines.

What is Petrol?

Petrol, also known as gasoline, is a clear, refined petroleum product that is used as a fuel for internal combustion engines. Petrol is made up of a mixture of hydrocarbons, and it typically contains around 30% aromatics, such as benzene.

  • It is also a highly volatile product, which means that it easily evaporates at room temperature. Petrol is produced through the fractional distillation of crude oil, and it is typically blended with other fuels, such as ethanol, to create gasohol.
  • Petrol can be used in both two-stroke and four-stroke engines, and it is the most common fuel used in cars and light trucks. Petrol engine vehicles typically have a higher fuel economy than diesel engine vehicles, but they also produce more greenhouse gases.
  • Petrol is a highly combustible product, so it must be handled with care. Storage tanks and pipelines must be properly designed and maintained to avoid leaks, and petrol must be transported in closed containers to prevent evaporation.

What is Diesel?

Diesel is a type of fuel used in Diesel engines. Diesel is a heavier fuel than gasoline, and it contains more energy than gasoline. Diesel engines are not as common as gasoline engines, but they are more efficient. Diesel is also used in some road vehicles, such as buses and trucks. Diesel fuel is not as volatile as gasoline, so it can be stored and transported more easily. Diesel engines also tend to produce less pollution than gasoline engines.

Difference between Petrol and Diesel

Petrol and diesel are two types of fossil fuels that are used to power internal combustion engines.

  • Petrol is a light crude oil that is distilled to produce fuel that is used in gasoline-powered engines.
  • Diesel, on the other hand, is a heavier crude oil that is refined to produce a fuel that is used in diesel-powered engines.
  • Petrol engines are typically more powerful than diesel engines, but they also consume more fuel.
  • Diesel engines, on the other hand, are more efficient but have less power.

Both petrol and diesel have their pros and cons, but they both ultimately serve the same purpose of powering internal combustion engines.


Although diesel engines are becoming more popular in passenger cars, the fact remains that petrol is still king. Diesel may have a few advantages over petrol, but until it can be produced in a way that doesn’t produce harmful emissions, petrol will continue to reign supreme.
