GoTankFuel prices on the drive to Croatia
The usual route from Germany runs through Austria and Slovenia, and each of the four countries controls fuel prices differently. A few habits save money on every tank.
Germany and Austria: fill up before noon
In both countries stations may raise prices only once a day, at 12:00, and may cut them at any time. Late morning is usually the cheapest time, just after noon the most expensive. If you set off early, fill up before 12:00. More in the noon price rule.
Slovenia and Croatia: leave the motorway
Both countries cap the price of standard petrol and diesel, but only off the motorway. Motorway stations set their own, usually higher, prices. A station in a town next to the motorway exit charges the capped price, and nearly all of them charge the same, so there is no need to hunt for the cheapest. More in fuel price caps in Croatia and Slovenia.
Check before each border
Which side of a border is cheaper changes with taxes, caps and the oil price, so no rule of thumb lasts long. Look at live prices on both sides before you cross, and fill up on the cheaper one.
Know the fuel names
- Germany and Austria: Super (E5), Super E10, Super Plus, Diesel.
- Slovenia: 95 and 100 octane petrol (bencin), dizel.
- Croatia: Eurosuper 95, Eurosuper 100, Eurodizel.
The pump labels are the same across the EU: a circle with E5 or E10 for petrol, a square with B7 for diesel.
With the GoTank app
GoTank shows official live prices in all four countries (and in Italy, if you take the route through Trieste). It switches country by itself at the border, uses each country's fuel names, and colours every price against the local average. On CarPlay the cheapest stations nearby are on the car's screen.
Rules checked on 9 November 2026. Prices and rules can change; the price on the pump always counts.
GoTank is free, with no ads and no account. The Android app is coming to Google Play soon.
