Oil marketers are taking steps to adapt to the growing demand for Compressed Natural Gas (CNG) as an alternative fuel source for vehicles. They are converting some of their trucks, previously used for transporting petrol to filling stations, into vehicles capable of supplying CNG to retail outlets.
