There is a joke that circulates among long-distance drivers in Nigeria, half bitter and half resigned: fuel doesn't get more expensive as you drive north, it gets heavier — heavier with diesel for the trucks that carried it there, heavier with the toll of bad roads, heavier with every checkpoint that slows a tanker down and adds another hour to a journey that eats into the margin a marketer can still call profit.

It is, in its own way, an accurate description of how Nigeria's petrol market actually works three years after the 2023 removal of the fuel subsidy handed price-setting over to market forces. Officially, Premium Motor Spirit is a national commodity, priced by the same crude cost and the same naira exchange rate wherever you buy it. In practice, a litre of petrol in Lagos and a litre of petrol in Maiduguri are two very different purchases, separated by a gap that can run past ₦200 per litre depending on the week.

Why Location Determines Price

The mechanics are straightforward, if easy to forget when you're the one paying at the pump. Nigeria's major fuel supply points — the Dangote Refinery in Lekki, the NNPCL depots, and the tank farms clustered around Lagos and the Niger Delta — sit overwhelmingly in the south. States closer to refineries or major fuel depots like Lagos, Port Harcourt and Warri tend to have lower prices, while northern and remote states pay more due to logistics costs, since every litre sold in Kano or Maiduguri has already traveled hundreds of kilometers by tanker truck before it reaches a filling station, and every kilometer adds cost: fuel for the truck itself, driver allowances, tolls, and the informal costs of navigating a road network where potholes and, in parts of the Northeast, security concerns can add hours or days to a delivery.

Among the ten states people most often ask about — Lagos, Rivers, Delta, Oyo, Anambra, Enugu, the FCT, Kano, Kaduna, and Borno — this logistics gradient plays out almost exactly as the map would predict.

Lagos and Rivers, sitting closest to refining and import infrastructure, have consistently shown the lowest prices nationally, with Dangote-supplied stations in particular dipping toward ₦1,075 per litre in early July before the mid-month hike, and independent marketers in the ₦1,100 to ₦1,200 range.

Delta, home to Warri's refining and depot infrastructure, sits close behind — cheap enough to benefit from proximity, but with slightly higher prices than Lagos in areas further from the depot clusters.

Oyo, Anambra, and Enugu occupy the middle of the range. They're far enough from the major coastal depots that transport costs add a noticeable premium, but still connected by reasonably functional road networks that keep the gap from widening too far — typically landing somewhere in the ₦1,150 to ₦1,250 range depending on the specific filling station and week.

Abuja (FCT), despite its status as the capital and its relatively good infrastructure, still sits a rung above the southern cities, reflecting its distance from the coastal supply chain even as its road network is better maintained than most.

Kano and Kaduna, the two biggest hubs in the North-West, absorb the fuller weight of that transport cost. Prices in these states have often run ₦150 to ₦250 higher than Lagos, driven by both the distance from depots and the sheer volume of onward distribution — tankers arriving in Kano frequently redistribute fuel to smaller towns across the wider North-West, adding another layer of markup before it reaches the final buyer.

Borno, at the far end of the spectrum, illustrates just how much security and infrastructure challenges compound the basic distance problem. Years of instability in the Northeast have disrupted road networks and made fuel transport riskier and more expensive, a dynamic that shows up in consistently higher pump prices — often the highest of any state in the country, sometimes ₦300 or more above what a Lagos motorist pays for the same product.

A Trader's View From Kano

Ordinary Nigerians living with this gap describe it less in percentages and more in what it forces them to give up. A generator-repair technician in Kano, who asked to be identified only by his trade rather than his name, put it plainly during a conversation about his monthly costs: he spends nearly a third of his income on fuel for the small van he uses to move between customers' homes, a burden that has pushed him to raise his callout charges twice in the past year just to keep pace. "Customer go complain," he said, "but if I no raise am, na me go dey suffer, because fuel no dey wait for anybody."

Traders moving goods between regions feel the gap even more acutely, because they absorb it twice — once on the outbound fuel cost, and again in the higher price northern buyers are willing to pay once transport costs are baked into everything from foodstuff to building materials. A trader who regularly moves tomatoes and onions from the North to Lagos markets described watching her transport costs rise faster than the prices she could realistically charge buyers accustomed to a certain range, squeezing her margin from both directions.

The Bigger Picture

None of this is unique to petrol, and none of it is new. Nigeria's regional price gaps have existed for as long as its road-dependent, depot-centered distribution network has existed. What has changed since the 2023 subsidy removal is the scale of the gap in absolute naira terms. When petrol cost ₦185 per litre, a ₦50 regional difference was noticeable but survivable. When the baseline is ₦1,100 to ₦1,400, that same proportional gap now represents ₦200, ₦300, sometimes more — money that matters enormously to a household or a small trader operating on thin margins.

The Dangote Refinery's growing output offers a partial counterweight, gradually pulling southern prices down as local supply reduces dependence on imported cargoes. But its geographic advantage, rooted in its Lagos location, means the refinery's price relief naturally reaches southern and south-western states first and most strongly, leaving the North-South gap intact for now, even as the national average shifts.

For the man in Kano fixing generators, the trader moving tomatoes south, or the family in Maiduguri budgeting for a week's transport, the map isn't an abstraction — it's the difference between a manageable month and one where something else has to give. And until Nigeria's refining and distribution infrastructure spreads more evenly across the country, that gap between Lagos and Borno, between the coast and the interior, looks set to remain one of the most consistent features of the nation's fuel market, price hike or no price hike.
