The forecasts last week indicated a new drop in fuel prices this week. But is that what actually happened? We went to verify.
The Automobile Club of Portugal announced on Friday, December 5, that the price of diesel was expected to decrease by two cents per liter, while gasoline was anticipated to drop by 0.5 cents per liter.
Calculations show that simple 95 gasoline dropped from 1.704 euros per liter to 1.700 euros per liter from Friday to Monday. This represents a decrease of 0.004 euros/liter.
Meanwhile, diesel, which cost 1.591€, is now priced at 1.579 €/liter.
Both fuels saw a slight decrease in price, closely aligning with the forecasted values.
