FAQs

CNG, also known as compressed natural gas, is an eco-friendly alternative to gasoline. Made by compressing natural gas (methane) down to less than 1% of its volume, CNG fuel is safer than gasoline and diesel because it is non-toxic and does not contaminate groundwater.

Yes, it is safe. The properties of CNG make it a safe fuel. It is lighter than air, so in case of a leak, it just rises and disperses into the atmosphere. Besides, a high auto-ignition temperature of 540 °C as against petrol’s 360 °C makes it a safe fuel. Also, in case of a leak, if CNG’s concentration in the air is less than 5% and more than 15%, the gas will not burn even in the presence of a spark.

The fuel bill based on the average running of the vehicle is approximately reduced to 50% after conversion of CNG at the present price of CNG and Petrol in Pune and other locations. For detailed savings, please refer to the Savings Calculator.

Yes, after conversion to CNG the vehicle can run on petrol whenever desired simply by flicking a switch on the dashboard.

CNG emits less carbon dioxide and other pollutants as compared to liquid fuels. Thus, CNG contributes to lowering air pollution and lowering harmful emissions.

Yes, a CNG kit is good for a car’s engine. The CNG kit makes your car a lot more efficient and economical. All big automobile brands i.e. Maruti Suzuki, Hyundai, Toyota, Honda are now producing CNG kit fitted cars and the number of CNG Cars are selling more than that of petrol or diesel.

CNG cylinders are manufactured from a special steel alloy and are seamless in construction. Their compact size allows them to easily fit even in a small car. An empty CNG cylinder with a 50 water litre carrying capacity (WLC) weighs 48 kg, with a length of 835 mm and a diameter of 316 mm, and can store approximately 8 to 9 Kgs of CNG – depending upon filling conditions, gas density, etc.

Yes, a diesel vehicle can be converted to run on CNG, but the conversion cost is higher than the conversion of petrol vehicles and under the current technology it cannot run on dual fuel mode. However, research in India is in the process of allowing diesel-run vehicles to function as dual-fuel on CNG.

Yes, all passenger vehicle manufacturers like TATA, Hyundai, Honda, Nissan, Ford etc. can be converted to CNG with the help of authorized CNG kits.

CNG kit is safe and simple. It gives years of trouble-free operation. It doesn’t require frequent servicing. Just as for all other fuels, it is advised to have routine services. As per Gas Cylinder Rules, 1981, the cylinder should undergo hydro-stretch testing every 3 years to check pressure tolerance. For detailed info, please refer to Hydro testing.

The cost of converting a vehicle to CNG depends on its type and the starting price of the conversion kit & fitting starts from ₹ 55000/-

The absence of any lead content in CNG helps avoid lead fouling of plugs, thereby enhancing plug life. One of the important benefits of CNG is that upon entering the engine in the form of a gas (and not as a spray or mist like other fuels), it doesn’t disturb the presence of lubricating oil in the engine and reduces chances of wear and tear.

After the CNG Kit fitment does help in the increase of the mileage but it depends on road conditions and driving habits. A cylinder with a 50 liter water-carrying capacity is capable of carrying approximately 9 kg of CNG. This is equivalent to 12.5 litres of petrol and will allow a run of about 150-160 km for a medium-sized 1300 CC car. Also, many OEM manufactured and retrofitted cars have electronic fuel gauge indicators fitted on the dashboard that give an approximate idea about CNG remaining in cylinders.

Yes, all petrol and diesel cars can be converted to CNG.
