The price of cooking gas has risen by 25 per cent to N1,500 per kilogramme from N1,200, adding to the rising energy costs faced by households and businesses.
This is even as the price of diesel, also known as Automotive Gas Oil, climbed to as high as N2,300 per litre at some filling stations and depots, representing a 4.5 per cent increase from the N2,200 recorded in August 2026.
The latest mid-day depot price report for September 16, 2026, showed sharp increases in diesel prices, particularly in Lagos and Port Harcourt, Rivers State.
Vanguard reported that in Lagos, Ibachem recorded the biggest increase, with its AGO price rising from N1,830 to N2,000 per litre, a N170 increase.
Ibeto followed with a N135 increase, from N1,835 to N1,970 per litre, while Duport and Integrated each recorded N110 increases to N1,940 per litre.
Ardova also raised its AGO price by N20 to N1,970 per litre, while Eterna and Rain Oil sold at N2,000 per litre. Nipco sold at N1,950.
The upward movement was also recorded in Port Harcourt, where African Terminal, Duport and Integrated increased their AGO prices by N110 each to N1,940 per litre.
In Warri, Matrix raised its diesel price by N40, from N2,080 to N2,120 per litre, the highest depot price recorded in the report.
The development could further increase operating and logistics costs for businesses and industries that depend on diesel for power generation, transportation and other operations.
Meanwhile, petrol prices in Lagos remained within a narrow range of N1,350 to N1,353 per litre.
Dangote, Pinnacle and A.A. Rano recorded N1 reductions, while Ascon and Integrated increased their prices by N2.
MRS maintained its price at N1,352 per litre, while Sahara and African Terminal increased their prices by N1 each to N1,352.
Some of the sharpest petrol price reductions were recorded in Calabar. Alkanes reduced its price by N17 to N1,338 per litre, while Matrix cut its price by N10 to N1,355. Mainland and Soroman also reduced their prices to N1,338.
In Warri, Matrix and Keonamex maintained petrol at N1,350 per litre, while Nepal and Prudent reduced their prices by N10 each to N1,340. Rain Oil retained its price at N1,350.
The divergent price movements underline the pressure facing diesel users, with AGO selling above N2,000 per litre at some depots even as petrol prices remain relatively stable.
Manufacturers, transport operators, telecommunications companies, small businesses and other diesel-dependent users could face higher operating costs if the upward trend persists.
Speaking with Vanguard, Lawal Kamaldeen, Vice-President, Oil and Gas Service Providers Association of Nigeria (OGSPAN), said the downstream sector had remained unstable, with frequent price increases.
“The downstream sector has been very unstable, characterised by frequent leaps in prices due to the prolonged USA-Iran war. Prices are likely to continue to be unstable in the coming weeks,” he said.
