The 4 Best Apps to Find Cheap Petrol Stations in 2026
The gap between the most expensive and the cheapest petrol station in the same city often exceeds fifteen cents per litre, which on a fifty-litre tank is more than seven euros per fill-up.

Frequently asked questions
Where do the prices in these apps come from?
They all draw on the same source: the official fuel price database of the Spanish Ministry for the Ecological Transition, which petrol stations are obliged to keep updated. That is why the prices match across apps. What changes is the interface, the update frequency and the extra features, not the figure itself.
Are the prices updated in real time?
Not exactly. Stations report their prices to the Ministry and the official database is updated over the course of the day, so there can be a lag of a few hours. In practice the figure is reliable, but if you are going to drive several kilometres out of your way for a few cents, it is worth checking the price on the sign when you arrive.
Is it worth a detour to refuel cheaper?
It depends on the distance. With an average consumption of six litres per hundred kilometres, a ten-kilometre round trip burns just over a litre. If filling the tank saves you five or six euros, it clearly pays off; if it saves two, it does not. The practical rule is not to go more than five kilometres out of your way unless the difference is large.
Do low-cost petrol stations sell worse fuel?
Fuel has to meet the same European standards whatever the brand, and unstaffed stations usually source from the same logistics depots as the big chains. The real difference lies in the additives premium brands put into their top ranges, whose effect on a modern car in normal use is limited.
