The Dangote Petroleum Refinery and Petrochemicals says it is considering stopping the sale of petrol to major marketers that continue to import petrol into Nigeria, amid concerns over product quality and the blending of imported fuel with products supplied by the refinery.

The proposed measure could take effect as early as this week, subject to further consultations and any last-minute intervention, according to sources familiar with the situation.

The immediate concern is that some marketers are allegedly blending imported PMS with petrol purchased from the Dangote refinery before distributing the resulting product to the market.

The refinery is concerned that such practices could make it difficult to distinguish between products supplied directly by Dangote and products subsequently blended or handled by third parties.
