Read on to get a comparison between Petrol Vs Diesel Vs CNG cars so that you can choose the most suitable one for yourself.

Whether the number of personal cars should be reduced to resolve severe air pollution in India has been a heated debate for years. Although it seems difficult to forbid private cars from running on roads, there is another feasible solution: to use a vehicle which is run on a less-emission fuel. Realising the need to use more environmentally-friendly vehicles, many Indian people have chosen to drive CNG or petrol cars, but others still use diesel ones, which are now becoming less popular with Indian auto buyers. Let’s come to a detailed comparison among the three most popular car types: petrol vs diesel vs CNG-powered cars so that you can make a wise a decision on choosing one for yourself.
