On the islands of the Dodecanese, Samos and Cephallonia, meanwhile, the average price was above the price ceiling.
The prefectures that had fully complied with the new ceiling were those of Lasithi on Crete, Chios, Evros and Evrytania. The six where average prices were around the government level were Rethymno, Grevena, Corfu, Cyclades, Lesvos and Fokida.
Nationwide, unleaded petrol was selling at an average retail price of 1.717 euro per litre.
Several petrol stations in areas where the price ceiling was imposed remained shut on Friday, protesting that the maximum retail price was actually lower than the price for wholesale and required them to sell at a loss.
A meeting between retail fuel vendors and the regional development ministry is planned for Friday to discuss the price ceiling, with fuel vendors demanding that this is either lifted or a similar price ceiling imposed on wholesale prices as well.
In three prefectures where limits have also been set on wholesale prices - namely, the Dodecanese, Rethymno and Samos - the retail prices nevertheless remain higher than the government-set limit.
