The steps are easy ,
Go to PSO shalimar pump, and choose the cylinder size , and inspect the kit , stand , etc.
Take the seller commitments and try to receive the users feed back from filling station,, here on PW there is not sufficient feed back from actual users.
My own experience is , earlier LPG was 45/- per liter at that time it was cheap (before Ramazan this year). for getting 7-8 km's in a liter compared to 100/- per liter petrol and avg of 9-10 per liter on petrol ,
Now its 70 per liter and 8 Km's per liter does not make u feel you very happy ... the actual increase in the price of LPG devastated every thing. and not sure what will be the peak rate this year ...
