From school days to speeches by advocates like Greta Thunberg, many of us feel inspired to help the planet. As we grow older, taking steps to reduce our carbon footprint becomes an integral part of our lifestyle. One effective way to contribute is by using cleaner fuel for your vehicle. If buying a new CNG car is not within your reach, retrofitting your current car with a CNG kit might be a viable alternative. However, before making this decision, there are several factors you should consider.

Environmental and Economic Benefits of CNG
Cleaner Emissions: CNG-powered vehicles are significantly cleaner than their petrol or diesel counterparts. They emit 20-30% fewer greenhouse gases and 95% less nitrogen oxide, resulting in reduced smog and improved air quality. This is particularly important for urban areas where air pollution can impact health.
Lower Fuel Costs: Over time, the cost of running a CNG vehicle is lower compared to traditional fuels. The upfront cost of a CNG kit is high. However, CNG costs less per kilometer. This can save you money over time, especially as petrol and diesel prices keep rising.
Lower Carbon Footprint: Using CNG cuts harmful emissions, leading to a cleaner environment. CNG vehicles cut climate change effects. They lower emissions of carbon dioxide, carbon monoxide, and particulates.
Key Factors to Consider Before Installing a CNG Kit
Before deciding to convert your vehicle to CNG, consider these essential factors:
1. Availability of CNG Fuel Stations
CNG stations are not as widespread as petrol and diesel stations. Depending on your location, you may face challenges in refuelling, which could lead to long waits or inconvenient travel to find a CNG outlet. Always check the local infrastructure before making a conversion decision.
2. Cost of Installation and Maintenance
Retrofitting your car with a CNG kit typically costs around INR 50,000, though this can vary based on your vehicle’s make and model. CNG vehicles might need more maintenance. This is because their fuel properties are different. Look at the initial installation cost and the ongoing maintenance costs to assess if it’s financially viable.
3. Authenticity and Quality of the CNG Kit
Not all CNG kits are equal. Buy from trusted dealers. Make sure the kit meets certification standards. Using substandard or fake kits can lead to performance issues or even safety risks.
4. Vehicle Compatibility
Not every car is suitable for a CNG conversion. Check with your Regional Transport Office (RTO) or the manufacturer to ensure your vehicle is compatible with a CNG kit. Older models may not have the necessary space or engineering specifications to support a CNG system. If your car is eligible, be sure to get the necessary permissions and update your Registration Certificate (RC) to reflect the new fuel type.
5. Impact on Vehicle Performance
Retrofitting your car with a CNG kit can affect its performance. In petrol and diesel engines, the fuel also serves as a lubricant, reducing wear on engine components. Since CNG lacks this property, you might experience increased engine wear and more frequent servicing. However, vehicles originally designed for CNG generally do not face these issues.
6. Insurance Considerations
Changing your car’s fuel type can also impact your insurance premiums. Typically, car insurance for CNG vehicles is around 10% higher than for petrol or diesel cars due to the perceived increased risk. When you switch your vehicle to CNG, update your insurance policy right away. Make sure to adjust your premium too.
Making an Informed Decision
When deciding to add a CNG kit to your car or buy a new CNG vehicle, consider the environmental benefits, cost savings, and practical challenges. It’s important to do your research:
- Compare Fuel Costs: Calculate potential savings on fuel over several years.
- Assess Refuelling Infrastructure: Ensure that you have easy access to CNG stations.
- Check Vehicle Compatibility: Make sure your car can handle a CNG kit without losing performance.
- Check Insurance Implications: See how the conversion impacts your premium and policy terms.
Final Thoughts
Switching to CNG helps cut your environmental impact and saves on fuel costs over time. Think about the upfront costs, maintenance, and possible changes in vehicle performance before making this decision. By taking the time to research and plan, you can ensure that your investment in a CNG kit will be beneficial both for your wallet and the planet.
Update your insurance policy. Also, check if local CNG stations are available. Whether you choose to convert your car or buy a new CNG vehicle, these steps are important. By making informed choices, you can have a greener, cheaper ride and help the environment.

Frequently Asked Questions (FAQs)
What are the environmental benefits of CNG?
CNG vehicles release 20-30% less greenhouse gases than petrol and diesel ones. They also cut nitrogen oxide emissions by 95%, which helps improve air quality.
How much does it typically cost to retrofit a car with a CNG kit?
The cost of retrofitting generally runs around INR 50,000, but this amount can vary depending on the make and model of your car.
Are CNG fueling stations readily available?
CNG stations are less common than petrol and diesel outlets. Availability varies by region, so it’s important to check local infrastructure before converting your car.
Can any car be converted to run on CNG?
Not all cars are eligible for conversion. Check with your Regional Transport Office (RTO) or car maker to ensure compatibility before buying a CNG kit.
How does retrofitting with a CNG kit affect car performance?
Retrofitting a petrol or diesel car with a CNG kit might mean more servicing. This is because CNG has lower lubrication properties. However, cars made for CNG usually work well.
