The Nigerian Midstream and Downstream Petroleum Regulatory Authority (NMDPRA) has ordered filling stations across the country to immediately calibrate and verify their fuel dispensers and totalisers after uncovering cases of under-dispensing of petroleum products to consumers.
The regulator warned that operators found repeatedly or seriously violating dispensing standards could face sanctions, including revocation of their operating licences.
In an industry circular issued in Abuja on Tuesday, September 22, the NMDPRA described under-dispensing as a “serious breach of consumer trust” and said it had intensified inspections and enforcement activities nationwide.
The Authority directed all retail outlet operators to check and calibrate their dispensing equipment to ensure that motorists and other consumers receive the quantity of petroleum products for which they have paid.
The NMDPRA said the exercise was intended to guarantee accurate measurement and protect consumers from losses arising from inaccurate dispensing.
“Outlets found to be under-dispensing, operating with improperly calibrated equipment, or otherwise compromising dispensing accuracy will be required to take immediate corrective action,” the regulator said.
It warned that persistent or serious violations would attract sanctions “up to and including revocation of the outlet’s licence”, in line with its regulations.
The directive has placed the accuracy of dispensing pumps under renewed scrutiny at a time when petrol prices remain a major concern for motorists, transport operators and businesses across Nigeria.
Under-dispensing occurs when the quantity of fuel delivered by a pump is less than the volume indicated on the dispenser and paid for by the customer. The problem can arise from inaccurate or improperly calibrated equipment, although regulatory enforcement may also target outlets where dispensing accuracy has been deliberately compromised.
The NMDPRA’s intervention therefore goes beyond a routine technical check. It places an obligation on operators to demonstrate that their equipment is functioning accurately and that customers are receiving the full value of their purchases.
The regulator has also brought the major petroleum marketers’ associations into the compliance exercise.
It directed the Major Energy Marketers Association of Nigeria (MEMAN), Depot and Petroleum Products Marketers Association of Nigeria (DAPPMAN), Independent Petroleum Marketers Association of Nigeria (IPMAN) and Petroleum Products Retail Outlets Owners Association of Nigeria (PETROAN) to promptly communicate the directive to their members and support full compliance.
PETROAN has since responded by directing its members nationwide to inspect their dispensing meters.
Its National President, Billy Gillis-Harry, said the association convened an emergency National Executive Council meeting after receiving the NMDPRA directive and instructed members to check their equipment. He also said PETROAN works with the Weights and Measures Division of the Ministry of Industry, Trade and Investment and the NMDPRA on the accuracy and functionality of dispensing meters.
The latest directive also builds on previous enforcement actions by the regulator against retail outlets accused of short-measuring customers. Punch reported that the NMDPRA had sealed several stations during enforcement operations in 2025 and 2026, including outlets in Rivers and Ogun states, over dispensing-related violations.
The renewed crackdown comes as Nigeria’s downstream petroleum market operates under a deregulated pricing framework, making accurate measurement an increasingly important element of consumer protection.
Since petrol prices are no longer determined by a uniform subsidy regime, consumers may encounter different pump prices from one location to another. Whatever the prevailing price, however, the quantity displayed on the pump should correspond with the quantity delivered.
For motorists, the issue is particularly straightforward: if a customer pays for 20 litres, the dispensing system should deliver 20 litres within the applicable measurement tolerance. A faulty or manipulated dispenser can turn even a small shortfall per transaction into a substantial financial loss when repeated across thousands of sales.
The NMDPRA said its action was part of its broader responsibility to protect consumers, promote transparency and uphold the integrity of petroleum product transactions.
The regulator’s warning also sends a message to filling station operators that compliance is no longer limited to maintaining licences and meeting product-quality requirements. The accuracy of the final transaction at the pump is itself a regulatory concern.
For consumers, the directive could restore some confidence if it translates into visible and sustained enforcement. But the real test will not be the calibration exercise itself; it will be whether the regulator can consistently identify offending outlets, distinguish equipment failure from deliberate manipulation, publish credible enforcement results and ensure that sanctioned operators do not simply return to the same practice. In a downstream market where every litre has a price and motorists already carry the burden of high transport and energy costs, accurate dispensing is not a minor technical issue—it is a basic measure of fairness in the petroleum trade.
