A new battle is quietly taking shape in Nigeria’s petrol market, and at the centre of it is a question that could have consequences far beyond the gates of the Dangote Petroleum Refinery: who gets to buy locally refined petrol, and who gets shut out?

The Dangote refinery has stopped selling Premium Motor Spirit (PMS), popularly known as petrol, to major marketers who import the product into Nigeria.
A refinery official confirmed the development, explaining that the decision was linked to concerns that some importers were allegedly mixing petrol supplied by the refinery with imported products.
According to the official, the refinery does not want its products associated with lower-quality fuel allegedly being brought into the country and blended with its own supply.
“We are not selling petrol to those who are importing, since they are trying to blend our high-quality products with their ultra-low-quality imported products,” the official said.
The development has immediately raised fresh questions about competition, fuel quality, imports and the future of Nigeria’s downstream petroleum market.
Dangote Draws A Line
The refinery’s position appears straightforward: if a marketer is importing petrol, Dangote does not want to supply that marketer.
Another source said the refinery was prioritising independent petroleum marketers and other buyers who are not involved in petrol imports.
That position, however, has placed the refinery at the centre of another contentious debate.
For marketers who depend on both local and imported supplies, the issue is not simply about where petrol comes from. It is about who controls access to the market and whether limiting supplies to importers could eventually affect competition and availability.
Some marketers have reportedly approached the court over the continued issuance of petrol import licences by the Nigerian Midstream and Downstream Petroleum Regulatory Authority.
Their concern is that if they are prevented from purchasing from Dangote while also facing restrictions around imports, their ability to maintain adequate supplies could become increasingly difficult.
And that is where the disagreement gets more complicated.
The Blending Allegation
Dangote has previously raised concerns over what it described as the possibility of its Euro-5 petrol being mixed with imported products.
The refinery argued that it had invested heavily in producing high-quality petroleum products and did not want those products blended with imported fuel of uncertain quality before being sold to Nigerians.
Its concern is also about identity.
Once products from different sources are mixed, the refinery maintains that it becomes difficult to determine which supplier should bear responsibility for the quality of the resulting product.
But some petroleum marketers are not convinced.
They have challenged Dangote to provide evidence that imported petrol entering the Nigerian market fails to meet the required standards.
One marketer accused the refinery of using the blending argument as a means of blocking petrol imports.
“We know what Dangote is trying to do. He is just trying to block imports,” the marketer said.
‘Can You Stop Nigerians From Mixing Petrol?’
The argument from the marketers takes the controversy into an unexpectedly simple territory — the fuel tank of an ordinary Nigerian motorist.
A marketer questioned how any supplier could realistically prevent petrol from different sources from being mixed.
The example was straightforward.
A motorist could buy petrol at a TotalEnergies station, drive some distance, and later buy another quantity from an MRS station after the first supply had almost run out.
The two products would eventually end up in the same vehicle.
“Can TotalEnergies say you should not mix its petrol with MRS petrol? No, it can’t. I don’t understand the game that the Dangote refinery is playing,” the marketer argued.
The analogy captures the heart of the dispute.
While Dangote is concerned about what happens when its products are deliberately blended before distribution, marketers argue that petroleum products inevitably move through a complicated supply chain where different sources can meet in storage facilities, filling stations and ultimately in consumers’ vehicles.
Where IPMAN Stands
The Independent Petroleum Marketers Association of Nigeria has also weighed into the dispute.
Hamed Fashola, the association’s National Vice Chairman, said the refinery appeared to be selective about the marketers it supplies, particularly those involved in importing petrol.
According to him, independent marketers are primarily concerned with obtaining products at competitive prices and will buy from whichever source offers the best deal.
“We buy our product anywhere we feel it is cheap. Anywhere we see the product, we go for it, both Dangote and the importers. We always go for the best price,” Fashola said.
That position highlights another reality of the downstream sector: marketers are businesses, and price remains a major consideration.
If locally refined petrol is competitively priced, marketers have an incentive to buy it. If imported petrol becomes cheaper or more readily available, they may look elsewhere.
IPMAN: Dangote Is Still Open For Business
Chinedu Ukadike, the National Publicity Secretary of IPMAN, offered a somewhat different perspective.
He said the Dangote refinery remained willing to transact with independent marketers, adding that the association’s members were not currently involved in importing petrol.
Ukadike said he could not independently confirm the allegation that importers were blending Dangote petrol with imported products.
However, he acknowledged the refinery’s right to take steps it considers necessary to prevent the adulteration of petroleum products.
“I believe that the Dangote refinery is open for business and that it will continue to sell to marketers,” he said.
He added that if Dangote had identified measures that could help discourage adulteration, the refinery and its technical experts were better positioned to determine how to address the problem.
A Bigger Fight Over Nigeria’s Petrol Market
Beneath the argument over blending lies a much bigger question about Nigeria’s evolving petroleum industry.

For decades, Nigeria depended heavily on imported refined petroleum despite being a major crude oil producer. The emergence of large-scale domestic refining capacity, particularly the Dangote refinery, was expected to change that equation.
But the transition has not eliminated competition between domestic producers and importers.
Instead, it has created a new contest.
On one side is a refinery insisting that locally produced petrol should not be mixed with products it considers inferior.
On the other are marketers who argue that Nigeria still needs multiple sources of supply and that imports remain relevant whenever domestic production cannot meet demand.
The Federal Government, meanwhile, has a responsibility to ensure that Nigerians have access to adequate petrol supplies while maintaining product quality and a competitive downstream market.
That leaves the controversy with a difficult question: Is Dangote simply protecting the quality and reputation of its petrol, or is the refinery’s decision becoming a tool to reshape who can participate in Nigeria’s fuel market?
For motorists, the answer may ultimately matter less than what happens at the pump.
If competition remains strong and supply is adequate, the dispute may remain largely a battle between companies and regulators.
But if access to petrol becomes tighter, prices rise or supply chains are disrupted, the argument will quickly move beyond boardrooms and courtrooms — and straight into the daily lives of millions of Nigerians.
