CNG Vs. Petrol Vs. Diesel – Which Used Car to Choose?


With attractive, used car loan interest rates, buying a second-hand car is now a hassle-free and quick process. However, the one thing where most people get stuck while buying a used car is the fuel type. With rising fuel prices and increasing sustainability consciousness, car companies have launched vehicles in various variants, such as petrol, diesel, and CNG. If you are confused about which one to pick, here’s a simple guide that can help you:


­ CNG Petrol Diesel
1 Cost If you are looking for a low-cost vehicle, a CNG car can considerably reduce your fuel expenditure. Petrol cars are inexpensive and great if you are on a tight budget. A used car loan n EMI calculator can help you determine the final loan amount you would need to buy such a car. But in general, these variants are priced lower than their counterparts. Diesel is a cost-effective option. Diesel prices are generally lower than petrol, and you can get diesel at most fuel stations.
2 Pollution If you care about the environment, a CNG car can be ideal, leading to lower emissions. Petrol may cause more pollution than the other two fuel types. Diesel is also an eco-friendly option with lower carbon emissions than petrol.
3 Vibrations CNG cars have low noise vibrations. Petrol cars offer the lowest noise vibrations. Diesel cars produce high noise vibrations.
4 Maintenance and convenience It can be hard to find a used CNG car with lower than 25,000 km on a factory-fitted CNG kit. Any vehicle that has been run more than this can lead to maintenance issues.

Another thing to keep in mind is that if you expect to use your car for only 800 km to 1000 km in a month, a CNG car can be a good option.

Petrol engines require more maintenance and can need frequent trips to the garage. Diesel engines have a longer lifespan as compared to other types of engines.
5 Inconveniences CNG stations often have long waiting queues. So, it can be time-consuming to refuel your car. And if your city does not have enough CNG stations, it can be challenging to use the car in the long run.

In addition to this, the CNG tank takes up most of the boot space of the vehicle.

The cost of petrol is higher than CNG and diesel. While you can take a used car loan to buy the car, you would have to spend more thereafter on petrol than other fuel types. Diesel models are the costliest variants of any car model. A used diesel car can be expensive as compared to other variants.

To sum it up

Used car loan interest rates are competitive and can help you buy a car with much ease. But the fuel type can alter the cost-effectiveness of the car in the long run. Hence, make sure to buy a vehicle after carefully assessing all pros and cons of the fuel type.
