This happens six months after they were declared operational, they say, leaving them reliant on the privately owned Dangote oil refinery and imports.
Nigeria, which has suffered years of fuel shortages, has spent about $2.4 billion since 2021 to revive the long-mothballed state-owned Port Harcourt and Warri refineries in the Niger Delta to end reliance on imported refined products.
The initial phase of the refurbishment was declared complete in December 2024.
However, fuel trading group the Petroleum Products Retail Outlets Owners Association of Nigeria said its more than 6 700 members were still dependent on imports and the Dangote Refinery, Africa's biggest, which is yet to reach full production capacity.
According to data from the regulator, by March, the last month for which full data is available, there was no gasoline output at Port Harcourt, previously Nigeria's largest refinery.
In the same month the Dangote refinery produced 20.6 million litres of gasoline, with imports adding another 25.19 million litres to supply, equivalent to 92% of Nigeria's 50 million litre-per-day gasoline market.
The initial phase of the refurbishment was declared complete in December 2024.
