1. Avoid Overfilling the CNG Tank
Avoid filling the CNG tank completely, as excess gas can easily move around or spill out. An overfilled tank can cause gas to leak out, wasting precious fuel. Just as it is not advised to overfill a petrol or diesel car, similarly a CNG tank should not be overfilled with gas.
2. Avoid excessive use of AC or heater
Like petrol or diesel cars, excessive use of the air conditioner or heater in a CNG car affects fuel consumption. Make sure that the AC or heater is turned on at least as AC or heater consumes a substantial amount of energy. When the AC or heater is turned on, the fuel consumption of a CNG car increases, which is similar to that of a petrol or diesel car. In such situations, the fuel consumption of a CNG car can impact the entire fuel bill of the owner.
3. Always keep the CNG gas lead tight
CNG gas can evaporate from the fuel tank if the gas is not properly sealed in the lead. Make sure the gas lead is tightly sealed. Also, make sure to park the vehicle in the shade or under a tree so that sunlight directly affects the car and there is less chance of CNG gas evaporating.
4. Always Maintain Tire Pressure
Regardless of the type of fuel, tire pressure plays an important role in ensuring optimum fuel efficiency. Lower air pressure in the tire means increased engine pressure which leads to higher fuel consumption. Therefore, always maintain the tire pressure to the optimum level recommended by the OEM.
5. Keep the engine running
Always tune the engine for better performance and optimum fuel efficiency. A poorly treated engine can wear out and result in reduced fuel efficiency.
6. Change the air filter at regular intervals
Always check the air filters and replace them at regular intervals. If the air filter gets clogged with dirt or dust, the engine consumes more fuel, which reduces performance.
