Mr Koro said the filling stations would be sanctioned and warned marketers to desist from selling petroleum products above the approved pump price.
Mr Korie said the marketers were not happy selling above N200 per litre because of the high cost of getting fuel to the stations but had no choice.
Mele Kyari, the group’s managing director, said that the NNPC could no longer keep up with the N170 per litre pump price of fuel.
The tanker was conveying petrol to Abuja when it started leaking while in motion.
The interception was made based on a tipoff, Customs spokesman Nasir Manga said.
The government had set up a technical committee to carry out the blending of the off-spec petrol, to comply with the acceptable standard.
“Nobody has given official statements that PMS is no longer under subsidy regime, …the general public cannot be buying products at N250, N220, N180, from the depot.”
Defaulting suppliers have been put on notice for remedial actions and NNPC is working with NMDRA to take necessary actions in line with subsisting regulations.
The regulatory agency boss said work was ongoing with other stakeholders to address the issue of substandard petrol imported into the country.
Last week, many fuel stations were closed, while others were seen hoarding or dispensing at low rates across the Nigerian capital.
