The President of the Dangote Group, Alhaji Aliko Dangote, had last month projected that the refinery would begin the production of petrol between August 10 and 12, 2024.
However, the 650,000 barrels per day capacity refinery could not roll out petrol on Monday for different reasons.
Findings showed that the ongoing crude supply crisis might be a setback to the refinery.
IPMAN National Vice President, Hammed Fashola, said the $20bn refinery would bring down the cost of fuel if it gets the needed support, especially as it has to do with crude supply.
According to him, the Nigerian National Petroleum Company Limited, which is the sole importer of PMS has been selling to marketers at N570/litre, but most IPMAN members buy from private depot owners at N700 and above.
