[Resolved]  Hpcl/BPCL/ioc — Regarding branded petrol

Sir,
I am a resident of bilaspur chhattisgarh.
Being a daily commuter i regularly take petrol for my bike from all the psu oil company outlets in my city.
But from the last one year these companies are creating artificial shortage of normal unleaded petrol which is less priced than the branded petrols like speed and extra premium.
You can only get the unleaded petrol for few days and most of the days they are selling branded ones which are costlier than the normal one.
My question is if they are making branded petrol by adding value added substances to normal ptrol then there shoul not be any shortage of normal petrol when there is no shortage of the branded one???
How can we confirm that they are not selling normal petrol under the ficitous tag of branded one when there is no proper checks on most of the petrol pumps???
My sincere request is to comsumer right activists and govt to look forward in this regard.
