That was back in summers, and on a working day. Not a single car was ahead of me.
I had to leave for Gujranwala and had filled from zoom PSO a day ago. Went to Attock CNG before leaving for Gujranwala and pressure was 180 i think. So no gas filled. Then I went to fill the tyres with correct pressure, and all the tyres were already at 30 PSI 
Reached Jhelum and it still had 110 bars remaining
