We refresh fuel prices every day at 08:00 Swiss time by cross-referencing the Italian Ministry of Enterprise (MIMIT, "prezzo_alle_8.csv" feed) and TCS Benzinpreis aggregated data for Swiss stations. The EUR/CHF rate comes from the ECB eurofxref daily feed so we can compare like-for-like in either currency. Listed prices are indicative — they can drift between snapshot time and your fill-up. Always confirm the price on the pump display or by phone before relying on it for a long trip.
