Saving a few cents per liter may seem like a game of luck, but there is an official tool that makes the task simple and quick. According to the Online Fuel Prices Portal, from the Directorate-General for Energy and Geology (DGEG), any driver can consult in real time the prices charged at all gas stations in the country, with just a few clicks.
The search for the most economical fuel becomes particularly relevant in a context of constant price fluctuations. For the week of December 1st to 7th, according to DGEG, simple diesel fuel should register a drop of around six cents per liter, while simple 95 gasoline should drop approximately 3.5 cents per liter.
These values come after several consecutive weeks of increases and place the average price of simple diesel at 1.565 euros per liter and 95 gasoline at 1.685 euros per liter.
How the official comparator works
The DGEG platform allows users to select the type of fuel, indicate the location by district and municipality and, if desired, filter by brand. The results show the updated prices for each station and can be viewed on an interactive map, making it easier to identify the closest and cheapest options. According to the same source, prices are updated directly by gas stations, ensuring reliability and transparency.
The portal distinguishes itself from independent applications by offering official data compulsorily communicated by stations, covering the entire continental territory without the need to register for the basic consultation. THE
The price difference between nearby stations can reach five to ten cents per liter, which, for those who fill up regularly, can represent significant savings throughout the year. Compared to the beginning of 2025, diesel is around 2.6 cents more expensive per liter, while 95 gasoline remains practically at the same level.
Portugal has relatively high fuel prices at European level. According to DGEG, the country occupies eighth place in the price of 95 gasoline, with values 7.7 cents above the European average. In diesel, the position is slightly better, ranking ninth.
Tips for maximizing savings
In addition to using the comparator, there are simple strategies that allow you to reduce costs. Planning your supplies, checking the portal before leaving home, taking advantage of loyalty cards and considering independent stations can make a difference. Avoiding refueling on motorways, where prices tend to be higher, is another measure that contributes to savings.
The portal also provides detailed statistics on the evolution of national average prices, allowing drivers to monitor trends and choose the most favorable time to fill up their tank.
Although there is no official mobile application, the site is responsive and works on smartphones, ensuring access to prices while on the road. Many third-party applications use data from , offering alternatives in the interface, but without deviating from official information.
In Portugal, where prices operate freely, each station defines its value, and the transparency of the platform allows you to find, with precision, the cheapest fuel available, according to the same source.
