There have been uncountable numbers of advertisements that talk about the cons of riding personal cars. Several campaigns have been on air and on TV that talk about car-pooling as a solution to the ever increasing and alarming issue of air pollution. After all, riding personal cars, with only 1 person sitting in a 4-5 seater vehicle, is not a prudent act. Also, with the ever increasing petrol diesel prices, it becomes even more of an ordeal. Nonetheless, if not decrease the number of cars on road, what we can least do is switch to a more environment-friendly fuel to reduce the carbon footprint. Let’s talk about which fuel is better – CNG vs Petrol vs Diesel Car!

CNG vs Diesel vs Petrol – Which Fuel will be the best for you?

Buying a car is a very crucial decision of one’s life. After all the society does not leave but definitely judges you according to the model, make, brand, size, and cost of your car. However, it will be better if you to negate such judgments from your mind and purchase a car that would be more useful to you rather than to the gossip mongers, who get a tea time conversation topic. Before taking the car purchasing decision, ask your self the following questions:

  • Why do I need a car? (To go to the office and back home, to go for long road trips, or just for the sake of societal norms.)
  • Which type of fuel will be best for me in terms of savings? (CNG vs Diesel vs Petrol Engine)
  • Which fuel will ensure my car remains in a good condition for a long time? (CNG vs Diesel Engine vs Petrol Engine)
  • Do I need a very big car or a small one will suffice my needs?

The answers to the above questions should govern your car purchasing decision and help you make your take – among CNG vs Petrol Car vs Diesel Car.

CNG vs Petrol vs Diesel Price – Car Purchasing Feasibility

Not so frequent Driving: If your car will run less than 500 Kms in a month (i.e. 5000 to 70000 kms in a year) then is it viable to buy a Petrol car.

Normal or Average Driving: If your car will run for about 800 – 1000 kms a month (i.e. 10,000 to 12,000 kms a Year) then CNG cars would prove to be more economical for you.

For a little above average driving: If your car will run in between 12000 to 14000 (i.e. 15,000 to 16,000 kms a year) then again, CNG would be an ideal fuel choice.

For high road driving: If your car will run for more than 2000 kms or more in a single month (i.e. 20000 kms in a year) then close your eyes and go for a diesel variant. It will help you save a lot on fuel costs and other upfront and maintenance costs.
