The increase is expected to occur for both diesel and petrol, with increases of around two cents per litre, according to forecasts released by the Automóvel Club de Portugal (ACP).

These estimates come at a time when the average price of simple diesel is €1,562/litre, while simple 95 petrol costs, on average, €1,645/litre, according to data from the Directorate-General for Energy and Geology (DGEG).

At the beginning of this week, diesel and gasoline had already seen an increase in price compared to the previous week.

The ACP emphasises that "these forecasts are made based on the assumption of maintenance of the extraordinary tax reduction measures applied by the government, to mitigate the increase in prices".
