then start filling lpg in your cylinder 
i dont think it can do 20km in one kg, might be true for a mehran which may do same with one kg of cng
didnt you said lpg is very expensive n useless n now u r saying who would need cng 
damn just saw this, so i parked the other car for nothing n all those people waiting in lines for nothing
just 2 days, wtf seriously, its summers not winters.... even in winters it was 3 days but in summers when it should be 4 days continous, its just 2 days
n i have to go to rwp tomorrow, seems gonna b back to expensive petrol with low average again 
called g11 pump, they dont know about new schedule yet, i hope they stay on this old one,will know by morning for sure
