Disadvantages of CNG Fuel

Limited availability of CNG stations, unlike petrol or diesel stations. It occupies at least 1/3rd of the vehicle's boot space. This makes it difficult for a sedan or other car owners to load the luggage in the cargo space. A CNG's car performance deteriorates after 3 to 4 years of usage. The engine's optimum performance also decreases by 10% after regular use for one year. It hampers the functionality of fuel injectors, making them dry quickly. It deteriorates engine performance in the long run. A CNG-powered vehicle has a lower fuel economy compared to other vehicles. The cost of conversion from conventional petrol or diesel-powered cars to CNG is high.
