Italy diesel up 1.5% on 19 September 2026, to €2.33/l

On 19 September 2026, the national average price of diesel in Italy rose 1.5% (€0.036 a litre), from €2.30/l to €2.33/l. Filling a 50-litre tank costs €1.78 more than the day before.

Correction (26 September 2026): figures recalculated from the complete daily data, after we removed prices from stations that had left the official feed. Earlier version — Diesel, national average on 19 September 2026: €2.276/l (now €2.309/l). Earlier headline: “Italy diesel reaches series high: €2.28/l”.

Correction (27 September 2026): 25 June 2026 was a partial day (only a little over half of the usual number of stations reported), which our daily series leaves out, so the period now starts on 26 June 2026, the first complete day. Prices and percentages are unchanged. Earlier version — period covered: 25 June 2026 – 19 September 2026.

Correction (30 October 2026): the Italian price history was rebuilt from the official MIMIT archive. Before, at some stations the standard diesel or petrol series had picked up other products (Blue Diesel, HVO, attended-service prices), so the daily averages were slightly off. Figures and percentages recalculated. Earlier version — Diesel, daily national average on 19 September 2026: €2.309/l (now €2.332/l).

Our daily national series for this market covers 26 June – 19 September 2026 — 86 days — so no comparison here reaches further back than that. It is the largest one-day change for diesel since 29 July 2026. Between 12 September 2026 and 19 September 2026 the national average rose 5.5%, from €2.21/l to €2.33/l.

Percentages, price differences and fill-up estimates are calculated from unrounded national averages. Prices shown in prose and tables are rounded to two decimal places.

Source and method

Prices are reported by station operators to Osservaprezzi Carburanti (Ministero delle Imprese e del Made in Italy). We collect them once a day and calculate the averages in this article ourselves. The national average is the unweighted mean of the 21,116 stations that reported a valid price for diesel, after we drop readings outside our plausibility range. Full method: how we calculate.

This article reports only what our calculations from station-price data show. It does not attribute the change to any cause.
