Eight filling stations within the Karu/Nyanya axis in the FCT had their pumps sealed off on Thursday by the Weight and Measures Department of the Commerce and Industry Ministry.
Mr David Adejuwon, Acting Director of Trade in the ministry, who led the team, said the filling stations were under dispensing fuel to their customers.
He said there was need for Nigerians to have value for their money whenever they buy goods and services.
Adejuwon said Nigerians had suffered enough without getting value for what they buy, especially at filling stations.
He said the monitoring exercise, which started on Thursday in Abuja, would also be carried out in the 36 states.
The News Agency of Nigeria (NAN) reports that some of the fuel stations affected were Mobil filling stations on Karu-Jikwoyi road found to be under dispensing diesel and kerosene.
NAN also reports that the two A. A. Rano stations in Nyanya and Karu had almost all its pumps sealed off for under dispensing fuel.
Others affected were AP filling station at Mopol Junction and NNPC mega station at Nyanya Shopping Centre.
NAN also reports that the only filling station found over dispensing fuel unknowingly was the NNPC mega station in Nyanya.
Mrs Grace Haruna, a customer, expressed delight at the monitoring exercise and called for constant routine checks at filling stations.
She also called on government to always support the exercise by providing the manpower and logistics needed.
