Example scenario on a 50-litre fill-up. Live prices and your own numbers in the app. How we calculate
The Chiasso border is one of the busiest in Europe, crossed daily by tens of thousands of cross-border commuters. The fuel advantage in Switzerland swings: in some periods diesel is cheaper than in Italy, in others the edge narrows, and the price moves with the euro/franc exchange rate.
Unlike Slovenia, in Switzerland you pay in Swiss francs (CHF): if you use a card, check the exchange fees your bank applies, because they can shrink the real saving. Rifuel factors the current exchange rate into the calculation.
For a commuter who passes through Chiasso anyway, filling up on the way back is almost free in detour terms. For someone driving from Como just for that, do the maths: with prices close together, the extra 8 km and time can cancel the advantage.
Frequently asked questions
Is it really worth refuelling in Switzerland from Como?
It depends on the day. When the price spread is wide yes, especially if you already cross the border; when prices are close, the ~8 km detour and CHF exchange can wipe out the advantage. Rifuel computes the live net saving.
How do you pay for fuel in Switzerland?
In Swiss francs (CHF). Many stations accept cards, but check your bank's exchange fees: they affect the real saving.
Do you need a vignette to drive to Chiasso for fuel?
To reach Chiasso from the border without using the Swiss motorway you don't need a vignette. You do need one for Swiss motorways: in that case add the cost to the calculation.
