Slovenia has government-regulated fuel prices that are often lower than in neighbouring countries. Every two weeks the government sets maximum retail prices for petrol and diesel, ensuring competitive rates for all drivers.
In Croatia fuel prices are often lower — but fill up in Slovenia if there's congestion at the border.
Before Obrežje on the A2 there are several stations near the Novo mesto exit.
Expect queues at the Dragonja border crossing during summer.
When refuelling in Croatia, note that cards may not work at all stations.
Prices are similar, but at Croatian motorway stations they are typically 5–10% higher.
We recommend stations at the Obrežje, Gruškovje, or Dragonja border crossings.
No, Croatia doesn't have a vignette system — tolls are paid per distance at toll stations.
Petrol 95 in Slovenia is usually 0.05–0.10 €/L cheaper. On Croatian motorways the difference is larger.
