Heavy truck traffic has returned to the gates of Dangote Petroleum Refinery, as fuel marketers rush to secure products at gantry prices that continue to undercut rival depots across Lagos, with diesel drawing the sharpest interest.

Data sourced from petroleumprice.ng showed long lines of tankers have formed at the refinery’s loading bays in recent days, a sign that the price gap between Dangote and other suppliers has widened enough to pull volume decisively in its own direction.

The pull is strongest in Automotive Gas Oil, commonly known as diesel, where the refinery’s pricing now sits well below what marketers are quoting elsewhere in the city.

According to prices reviewed by Petroleumprice.ng, Dangote sold AGO at N1,580 per litre on August 19, a level that leaves it N70 cheaper than Pinnacle’s N1,650 and as much as N85 below Ardova’s N1,665, based on depot prices recorded a day earlier. Ibeto, Ibachem and Duport were each quoting N1,660, matched by Gulf Treasure, Integrated, African Terminal and T.Time.

The spread is smaller but still present in Premium Motor Spirit. Dangote’s PMS stood at N1,175 per litre on August 19, compared with N1,195 at both African Terminal and Integrated, and N1,198 at Nipco, going by prices logged on August 18.
