Some members of the Independent Petroleum Marketers Association of Nigeria (IPMAN) in the South-east say they will no longer guarantee the supply of products at the approved pump prices.
The marketers spoke in separate interviews with the News Agency of Nigeria (NAN) in Awka on Thursday.
They said they could not sustain the availability of the petroleum products, when they exhaust their current stock.
A NAN correspondent, who monitored the supply of premium motor spirit, popularly called petrol, in Awka, reported that most outlets now sell the product for between N180 and N195 per litre.
