The regulation system and what it means for city and regional prices.
Slovenia is one of the few European countries where the state directly sets the maximum price of 95 petrol and diesel at fuel stations off the motorway network. This regulation follows a 14-day cycle, meaning the maximum price is recalculated every fourteen days based on movements in world oil prices.
For drivers, this means that prices at city and suburban stations across the country are fairly uniform, while the picture on the motorway is completely different. Motorway service stations are not included in the regulation, so operators there set their own prices, which usually results in a higher price per litre.
Every 14 days a new maximum price is calculated for 95 petrol and diesel at stations off the motorway, while the regulated price stays fixed for that period. This means prices in cities do not fluctuate day to day the way they might in an unregulated market, but instead follow a clear, predictable rhythm.
Travellers passing through Slovenia can check current prices by city and region on the Slovenian regions pages, which are refreshed several times a day.
Because motorway station prices are not regulated, the difference compared with a regulated station in a nearby town can be significant. The saving on a 50-litre fill-up is calculated by multiplying the gap between the regulated and unregulated price per litre by 50 litres — current figures are shown on our live map.
Drivers travelling along the main transit corridors can find details on the transit corridors page, which explains where it makes sense to leave the motorway to fill up at a regulated station.
On KjeJeGorivo, cheaper stations are marked in green and more expensive ones in red. Dark green marks regulated stations off the motorway, while light green marks the cheapest station within the selected area, allowing a quick visual overview without reading long lists.
This colour system is especially useful at border crossings, where prices differ between neighbouring countries; a comparison is also available on the Austria to Croatia fuel page.
Since a vignette is mandatory for motorway driving and can be purchased on the [official DARS website](https://evinjeta.dars.si), it is worth buying it in advance and planning a fuel stop at a regulated station right after leaving the motorway.
On the Karavanke–Obrežje corridor, the gap between motorway and city prices is often noticeable within just a few kilometres, so it pays to check current prices before stopping, which we also track in our blog.
