Fuel prices are rising and demand for information is exploding. Here’s where it’s cheapest to fill up in the region. Over the past week, searches for terms such as ‘fuel prices’ and ‘how much is petrol’ reached their highest level in 2025.
A new comparison of fuel prices in seven countries in the region reveals large differences in what we pay for a litre of fuel – in some cases more than €0.40 per litre.
Bosnia and Herzegovina is by far the cheapest
On average, Bosnia and Herzegovina has the lowest prices for both petrol and diesel, while fuel prices in Montenegro are the lowest for LPG. On the other hand, fuel in Austria and fuel in Serbia are the most expensive – especially diesel and LPG. For example, a driver from Croatia who fills up with diesel in Bosnia and Herzegovina can save around €7.50 on a 50-litre tank.
Why such differences?
Fuel prices are affected by many factors:
● Tax policy and subsidies (some countries, such as Hungary, previously had frozen prices)
● EU membership (Bosnia and Herzegovina and Montenegro are not subject to the same energy directives; in Slovenia fuel prices are still regulated)
● Currency stability and import/export costs
● Proximity to refineries and ports
Tips for drivers
● If you’re travelling through the region, it pays to plan where you’ll fill up – the difference per litre means tens of euros on a full tank.
● Crossing the border to fill up is increasingly common – especially among people living in border areas such as Slavonia and Dalmatia.
● It pays to follow weekly price changes – in Croatia prices are adjusted every two weeks (on Tuesdays)
Conclusion
With current global events such as the situation in the Middle East affecting the oil market, and growing consumer interest in fuel prices, it’s clear that drivers in the region are looking for ways to save. Bosnia and Herzegovina remains a fuel paradise for those who know where to look, while Austria and Serbia stay at the top of the price table.
If you’re planning a trip this summer – fill up wisely.
