The trend this week will be for a rise of 0.0147 euros in diesel and a rise of 0.0360 euros in 95% petrol,” a source from one of the national own-brand gas stations told 'Executive Digest'.

At the main national gas stations, “the evolution of prices in euros points to an increase of up to two cents in diesel and up to four cents in the price of 95 petrol”, added another source.

Data from the Directorate General of Energy and Geology (DGEG) shows that the average price of a litre of petrol in Portugal is currently 1.71 euros, while diesel costs 1.581 euros. Prices may vary at different service stations, as the price set by the network also takes into account the level of competition, supply and demand in each market and the level of fixed costs at each station.

Looking back at the beginning of the year, diesel has already fallen from 1.609 to 1.581 euros/litre. In other words, filling up the tank with 60 litres of fuel has become 1.68 euros cheaper. 95 petrol has fallen from 1.722 to 1.71 euros/litre, which represents a saving of 0.72 euros.
