Frequently Asked Questions

How much can I save by converting my vehicle to CNG?

Savings depend on your vehicle type, daily usage, and local fuel prices. Typically, CNG users save 30-50% on fuel costs compared to gasoline or diesel. Use our calculator to get personalized savings estimates.

What is the difference between CNG mileage and gasoline mileage?

CNG mileage is measured in km per kg, while gasoline is measured in km per liter. Generally, CNG provides better fuel economy and costs less per unit of energy compared to conventional fuels.

Is CNG better for the environment than gasoline?

Yes, CNG produces significantly lower emissions than gasoline or diesel. It reduces carbon monoxide by 70-90%, nitrogen oxides by 35-60%, and particulate matter by 90% compared to conventional fuels.

What are the maintenance benefits of using CNG?

CNG burns cleaner than gasoline or diesel, resulting in less engine wear, longer oil life, and reduced maintenance costs. CNG vehicles typically have longer engine life and require fewer tune-ups.

How do I convert my vehicle to CNG?

Vehicle conversion to CNG should only be done by authorized retrofitment centers. The process involves installing a CNG kit, which includes storage tanks, pressure regulators, and fuel injection systems.

Are there any disadvantages of using CNG?

CNG vehicles have slightly reduced boot space due to storage tanks, limited refueling infrastructure compared to gasoline, and initial conversion costs. However, the fuel savings typically offset these disadvantages within 1-2 years.

How accurate are these savings calculations?

The calculations provide estimates based on the input parameters. Actual savings may vary depending on driving conditions, vehicle maintenance, local fuel prices, and individual driving habits.

What vehicles are suitable for CNG conversion?

Most gasoline-powered cars, auto-rickshaws, buses, and trucks can be converted to CNG. However, it's important to check with authorized dealers for vehicle-specific compatibility and warranty implications.
