Dear, I had a trip from Peshawar to Lahore on Motorway, and before leaving I inquired about the CNG availability from my cousin in Lahore and he told me that CNG will be available in Punjab from Friday till Monday morning 5 AM, so on Saturday I left Peshawar at 5.PM with half tank filled with Petrol and tank full of CNG, when I reached Burhan interchange and thought to fill the CNG again as don't wanted to fill the gas at chakri and when I exit from the motorway and checked the CNG station and found out All stations were closed, so decided to continue my journey till the gas end and then will switched Petrol, I checked all the CNG Stations on motorway and on interchange but all were closed and then some one told me that CNG is available only on Pindi Bhattiyan interchange, so I went there and saw more than 100 cars parked for their turn, so I turned around and continue my journey to Lahore on Petrol, Even all the CNG stations were closed in Lahore. so I stayed on Lahore for 1 day and drove the car on Petrol, so while coming back to Peshawar on Monday all the CNG stations were open. I filled the tank in Lahore, then again put some gas in sukhi on Motorway, then from Bhera, exit from motorway and filled the gas and then again on motorway, then exit from Motorway from Burhan filled the tank in Hassan abdal and then back to Motorway for Peshawar, total expense was 6 thousand worth of Petrol, Still 2 thousand Petrol is in tank, and 2600 Rs of CNG for the round trip. Further I advise you not to fill the CNG from CNG stations on Motorway, as they don't have good pressure and they cheat you, so always fill the gas from the station out side interchange Exits.
