Gasoline price archive for Chiasso — 2026-05 (cross-border guide)

Methodology and context for the gasoline price in Chiasso

For 2026-05, this page shows available daily gasoline averages for the Chiasso zone. The monthly average of 1.888 CHF/litre is the arithmetic mean of numeric values present in the history, not an average weighted by litres sold. A day without an observation has no price and is not filled with the previous value. The station sample can change over time and does not necessarily represent every station in the area.

Swiss prices originate from the TCS radar, which collects user reports. This archive preserves snapshots from our pipeline: the date identifies the sample day, not the time each operator changed its pump price. A monthly average can hide differences between stations and days. Before choosing where to refuel, open the current page, check the collection date and confirm the price at the station. Missing observations do not establish that a price remained unchanged. TCS Benzinpreis

To compare Chiasso with an Italian location, use the same fuel, observations from comparable periods and a dated CHF/EUR exchange rate. Convert both prices to one currency, multiply the difference by the litres you intend to buy, then subtract actual detour costs. Distance, consumption, tolls and time depend on your journey. This history does not establish a universal break-even threshold or a fixed premium at border stations.
