If these predictions are confirmed, next week, a litre of simple diesel should cost 1,557 euros, while the price of a litre of simple 95 petrol will be 1,743 euros.

This week the average price of a litre of petrol in Portugal was 1,748 euros and diesel was 1,552 euros, according to data from the General Directorate of Energy and Geology (DGEG), values that reflected three consecutive weeks of declines in both fuels.

These forecasts for the cost of fuel take into account the maintenance of extraordinary tax reduction measures applied by the Government, to mitigate the rise in prices.
