Ghana’s Auditor-General found that millions of litres of petrol reached pumps nationwide without mandatory quality checks between 2023 and 2026, weaknesses the fuel regulator disputes calling a scandal.
The Performance Audit Report on the Operations of the National Petroleum Authority (NPA), dated June 24, 2026, found that 87.3 million litres of petrol moved through the market between January 2023 and May 2026 without going through the mandatory fuel marking process that verifies authenticity and quality. Auditors said the gap meant they could not confirm the fuel met required standards once it reached consumers, and warned it also left the state unable to verify whether it collected the taxes and Uniform Petroleum Pricing Fund (UPPF) margins owed on those volumes.
The NPA has pushed back on how the findings have been characterized. In a statement issued Monday, the Authority’s Corporate Affairs Directorate said the audit does not establish any financial or revenue loss and rejected media reports describing the findings as evidence of corruption or “rot.” The Authority said it would keep working with the Audit Service to implement the report’s recommendations.
The audit also found gaps in the technology meant to catch contamination at the pump. Of roughly 4,000 retail fuel stations nationwide, 557 lacked an Automatic Tank Gauging System (ATGS), the equipment used to continuously monitor underground tanks for water, leaks and abnormal fuel levels. Among the 3,443 stations that had one installed, only 1,813 were fully automated, while 1,630 ran only partially, limiting how much contamination the systems could actually catch.
Physical inspections fell over the same period even as the retail network grew. The NPA’s inspections dropped 19.82% between 2023 and 2025, from 32,012 to 25,598, while the number of licensed filling stations rose from 3,950 to 4,000.
Those gaps showed up in specific cases the audit documented. At a GOIL station in Zuarungu, Bolgatanga, fuel passed a marker test in August 2023, but a customer complained six days later that the petrol contained water, and a follow-up inspection found roughly 180 litres of water in the underground tank. At Nasona Oil Outlet in Kanvili, Northern Region, the audit found the station sold 36,000 litres of diesel over three months before a water-contamination complaint reached the NPA, by which point all the fuel had already been sold. A separate case involving Mobik Service Station’s Fijai and Nkroful Junction branches ended with a customer’s vehicle developing engine damage; NPA lab tests later confirmed the fuel from both branches was substandard.
The audit found similar strain in fuel transport oversight. As of April 9, 2026, only 2,514 of the country’s 4,904 registered Bulk Road Vehicles, about 51%, held valid operating licences. NPA management told auditors it had not deactivated the remaining tankers because doing so risked disrupting fuel distribution, an explanation the Auditor-General rejected, warning that unlicensed tankers offered no assurance they met safety or technical standards.
The Auditor-General’s recommendations call on the NPA to strengthen fuel marking, enforce functioning ATGS at every station, properly license and monitor transport vehicles, and move toward real-time surveillance of retail outlets.
