Italian diesel crossed €2.00 per litre within a week of the Iran war and never came back. Between March 5 and April 4, 2026, Gasolio rose from €1.826 to €2.106/L – a 15.3% increase across more than 21,000 stations in the Fuelconomy network. Benzina, by contrast, barely budged: +2.3% over the same period, landing at €1.774/L. That divergence – the widest diesel-petrol gap among the countries Fuelconomy tracks – tells a story about government intervention, global supply chains, and who actually pays when oil prices spike.
This analysis is based on Fuelconomy's historical price dataset covering more than 21,000 Italian stations from March 5 to April 4, 2026. Daily national averages, minimums, and maximums are calculated from official MIMIT (Ministero delle Imprese e del Made in Italy) price feeds. City-level data covers 155 Italian cities with 20 or more reporting stations. All figures in this article are measured historical values from the snapshot period.

Gasolio started March 5 at a national average of €1.826/L. By March 11 – just six days later – it had already crossed the €2.00 threshold, hitting €2.022. The price kept climbing through mid-March, peaking at €2.133 on March 20. That's a 16.8% surge in barely two weeks, driven by Brent crude climbing above $100/barrel after the Strait of Hormuz disruptions cut roughly 20% of global oil transit.
The Italian government intervened on March 19 with Decree-Law No. 33, cutting excise duties by €0.25/L on both diesel and petrol. The effect on diesel was immediate: prices dropped from €2.133 on March 20 to €1.981 on March 22 – a €0.15 single-day correction. But the relief was short-lived. By March 26, diesel had already climbed back above €2.05, and it continued rising through the rest of the period, ending April 4 at €2.106.
The pattern is clear: the government shaved roughly €0.15 off the peak, but crude oil prices climbed fast enough to erase the benefit within a week.
Benzina tells a completely different story. It peaked at €1.895 on March 20 – a 9.3% rise from the start – then dropped sharply to €1.728 on March 22, the day after excise cuts took effect. Unlike diesel, petrol stayed down. It drifted sideways between €1.73 and €1.77 for the remainder of the period, ending at €1.774 on April 4.
The net result: petrol rose just €0.04/L over 30 days. On a 50L tank, that's €2.00 extra. Diesel drivers, meanwhile, are paying €14.00 more per fill.
Why the divergence? Diesel is a globally traded commodity with tighter refining margins and direct exposure to Hormuz disruptions. Petrol refining has more regional flexibility, and Italian excise duty cuts were proportionally more effective on a lower base price. The combination meant that government intervention effectively neutralised the petrol spike while barely denting the diesel one.
Italy's emergency decree deserves a close look. The €0.25/L excise reduction came into force on March 19, initially for 20 days (expiring April 7), at a cost to the treasury of €417.4 million. The package also included a 28% tax credit on diesel for trucking companies and €10 million for the fishing sector, bringing the total to €527.4 million.
The data shows the intervention in real time:
For petrol, the cut worked. Benzina dropped €0.17 overnight and stabilised roughly €0.10 below pre-crisis levels. For diesel, the cut bought a week of breathing room before crude prices overwhelmed it. By the last week of the snapshot period, the government had already extended the measure through May 1 at a further cost of roughly €500 million.
Southern Italy – particularly Campania and Sicily – absorbed the sharpest increases. Among cities with 20+ reporting stations, Gasolio rose fastest in these areas:
The Sicilian cities of Catania and Siracusa stand out: large station networks, both above +17%, and both ending above €2.09/L. The Campania cluster (Pagani, Mascalucia) reflects the region's heavy dependence on road freight for goods distribution – when diesel costs surge, these areas feel it first.
Even after adjusting for the excise cut, diesel in every single Italian city with 20+ stations ended the period above €2.00/L. That is a first in Fuelconomy's dataset – the entire country is now in "expensive diesel" territory.
Most expensive (Gasolio, April 4):
Cheapest (Gasolio, April 4):
The spread between cheapest and most expensive is just €0.158/L – compressed compared to normal times. During a crisis, prices converge upward. There are fewer bargains to be found, and the savings from shopping around shrink.
For drivers in Italy's major metropolitan areas, here is how diesel and petrol ended the 30-day period:
Milan is the priciest major city for diesel at €2.148, while Catania saw the steepest increase at +17.2%. The petrol column is remarkably uniform – every major city sits between €1.76 and €1.81, with increases capped between 1.7% and 2.7%.
Italy has one of the most fragmented fuel markets in Europe, with 25 distinct fuel types tracked in our dataset. During a price shock, premium variants don't all move the same way:
Blue Diesel and HVOlution absorbed the shock better (+9.9% and +10.7%), likely because their pricing includes a larger fixed margin that doesn't scale linearly with crude costs. Supreme Diesel and Excellium Diesel tracked standard diesel closely, offering no protection from the spike. If you're paying a premium for "better diesel" during a crisis, the data suggests Blue Diesel or HVOlution at least partially shields you from the worst of crude price pass-through.
GPL (LPG) deserves its own section. It started the period at €0.695/L and ended at €0.749/L – a 7.8% rise that kept it well under €1.00. For roughly 4,500 stations with GPL pumps across Italy, the cost of a 50L fill-up went from €34.75 to €37.45 – an increase of just €2.70.
Compare that with diesel: €14.00 more per fill-up. A driver switching from Gasolio to GPL would save roughly €67 per 50L tank at current snapshot prices – though GPL vehicles consume roughly 15 – 20% more fuel per kilometre, so the net saving is closer to €50 per equivalent distance.
Metano (CNG) had a tougher month: +10.3%, from €1.420 to €1.566/L. Still cheaper than diesel per litre, but the advantage narrowed during the crisis.
Italy's fuel tax burden is among the highest in Europe. Before the crisis, roughly 62% of petrol prices and 58% of diesel prices were tax. The €0.25/L excise cut cost the treasury €417.4 million for the initial 20-day period, and the government has since extended it through May 1 at an additional cost estimated around €500 million. Finance Minister Giancarlo Giorgetti warned publicly that if the war continues, petrol could reach €3/L, and that Italy is running out of fiscal room for further cuts.
On April 4 – the last day of our snapshot period – Italy's finance minister joined counterparts from Germany, Spain, Portugal, and Austria in demanding that the EU introduce a windfall profit tax on energy companies, arguing that national excise cuts alone cannot absorb the crisis.
Cost to Italian drivers (diesel, per month): A commuter filling up twice a week with a 50L tank now pays roughly €112/month more than before the crisis. That adds up to approximately €1,340 over a full year if prices remain at current levels.
Between March 5 and April 4, 2026, Gasolio rose from €1.826/L to €2.106/L – a 15.3% increase. Based on Fuelconomy data from over 21,000 Italian stations, every city in our dataset now sits above €2.00/L for diesel.
Benzina rose just 2.3% over the same period. Italy's €0.25/L excise cut on March 19 was proportionally more effective on petrol's lower base price, and petrol refining has greater regional flexibility than diesel, which is more directly exposed to Hormuz disruptions.
As of April 4, 2026, Gorgonzola and Seregno (both near Milan) topped the list at €2.195/L. Among major cities, Milan averaged €2.148/L. Use Fuelconomy's live price map to compare stations in your area before filling up.
GPL rose just 7.8% to €0.749/L, keeping it well under €1.00. A 50L fill costs roughly €37.45 compared to over €105 for diesel. Even accounting for GPL's higher consumption per kilometre, drivers can save around €50 per equivalent tank. Roughly 4,500 Italian stations carry GPL.
The initial 20-day cut (March 19 – April 7) has been extended through May 1, 2026. The extension costs an estimated €500 million. The government has warned that further extensions depend on the geopolitical situation and available fiscal room.
Based on Fuelconomy's snapshot data, a driver filling a 50L tank twice per week pays roughly €112/month more than before March 5. That equals approximately €1,340/year if prices hold at April 4 levels.
It depends on the brand. Blue Diesel (+9.9%) and HVOlution (+10.7%) absorbed the shock better than standard Gasolio (+15.3%). However, Supreme Diesel (+15.4%) tracked regular diesel almost exactly, offering no price protection.
