Overview
- ADAC data show diesel nationwide averaged slightly below its February 27 pre‑war level over the recent weekend, while Super E10 remains about 4.4 cents per liter above that benchmark.
- Journalists and market data attribute the drop to a fall in oil prices after first reported progress in US–Iran negotiations plus the government’s two‑month Tankrabatt that trims fuel taxes by 16.7 cents per liter.
- The Tankrabatt ends on June 30, raising the risk that retail prices will rise from July 1 if oil markets do not sustain current relief.
- A pricing rule borrowed from Austria that allows only one daily price increase at noon produces large intraday swings, with ADAC finding average gaps near 15 cents for E10 and over 18 cents for diesel and the cheapest pumps often late afternoon.
- Cross‑border arbitrage remains common because tax and VAT differences make foreign fuel substantially cheaper for some drivers, prompting regular long trips that can save motorists tens or hundreds of euros per run.
