Do you strictly run on CNG? How often you pump CNG? Once a day? Nearby kiosk then pump? Or goes a few days on petrol until reach pump?
For me only pump when nearby. If not run petrol. Not economical to rush down to pump if too far. The time taken and savings can be recover if you take one or two trips. Agree?
I everyday pump cng...even i left half tank,if i nearby cng station,i'll go top up full...
