The warning is coming as the retail stations of the Nigerian Petroleum Corporations in the Federal Capital Territory and its environs have increased the pump price of the PMS to N145 from the initial N141.
Similarly, some private marketers of petroleum products are now selling petrol in their outlets at N150 per litre.
One of Punch correspondents reported that some filling stations in Lagos and Ogun states had refrained from selling the product.
For instance, the Oando filling stations at Alapere and Berger as well as the Mobil filling station opposite the Magodo Estate gate did not dispense the product to members of the public since Friday.
Similarly, the Ascon and NNPC stations between Arepo and Magboro, off the Lagos-Ibadan Expressway, Ogun State, did not sell the product on Sunday, raising fears of another round of fuel scarcity, the Punch reports.
