The Department of Weights and Measures in Lagos, a unit of the Federal Ministry of Trade and Investment, has warned petrol stations' operators to adhere strictly to the ministry's regulations.
Mrs Crescentia Erukpeme, Head of the department's Lagos office, gave the warning on Saturday in Lagos in an interview with the News Agency of Nigeria (NAN).
She said the warning became necessary because some filling stations were in the habit of under-dispensing products to customers.
"The agency is committed to ensuring conformity in weights and measures of all commodities in the country, especially as it concerns petroleum products," Erukpeme said.
She said the agency had set up surveillance teams to check the activities of filling stations.
"We will not hesitate to seal any filling station caught under-dispensing products.
"We will also not fail to prosecute if a filling station continuously engages in this mischief act," the official said.
She said her department would ensure any station caught with malfunctioning pumps would also be made to immediately change or repair them.(NAN)
