cng is closed 3 days a week right now
in winters cng i assume would be closed 4 days a week atleast with super long queues and low pressure on days its open
in a new kit, i am not sure how long will it take to breakeven the kits cost
but for a guy like me who has a old car and cng installed, it makes my running cheaper by 4 rup per km atleast compared to petrol
