Drivers in Portugal face mixed fuel trends for the week of August 31 to September 6, 2026, as diesel prices drop significantly while gasoline edges up. According to industry estimates, diesel will fall 7.5 cêntimos per liter, pushing average prices below the two-euro threshold.
Diesel Prices Drop Sharply Below Two Euros
Motorists across mainland Portugal will experience immediate relief at the pump for diesel vehicles. Following two weeks of noticeable increases that totaled 10.6 cêntimos, the price of simple diesel is projected to decrease by 7.5 cêntimos per liter starting Monday, as reported by industry sources. If these forecasts hold, filling a standard 50-liter tank will cost approximately 99.75 €, bringing the average price per liter down to 1.995 € or 1.996 € depending on the tracking source across regional providers.
Este valor reflete um aumento substancial face aos valores registados a 1 de fevereiro de 2026, data em que o gasóleo custava em média 1,659 € por litro, o que representava menos 34 cêntimos em relação à previsão atual, enquanto a gasolina se cifrava nos 1,764 € por litro.
This sharp descent pulls the average price of diesel back below the psychological two-euro threshold. Weeks earlier, costs had climbed past that mark, reflecting sustained pressures from international crude markets and geopolitical tensions in the Middle East, including the ongoing conflict involving Iran and the closure of the Strait of Hormuz, through which passes 20% of the trade of petroleum and natural gas.
Gasoline Continues Its Upward March
While diesel users catch a break, drivers filling up with simple 95 gasoline face another week of higher expenses. Projections from the Automóvel Clube de Portugal (ACP) indicate that gasoline will rise by 1.5 cêntimos per liter. This upward adjustment lifts the average price from 1.989 € to 2.004 € per liter, making the refueling of a 50-liter tank hit the 100 € mark at standard pump rates.
Because of these diverging paths, gasoline and diesel effectively swap positions regarding which fuel averages above two euros per liter. The incoming rise marks the third straight week of increased gasoline costs for Portuguese consumers.
Other estimates from the Associação Nacional dos Revendedores de Combustíveis (Anarec), ceded to Lusa, previously pointed toward alternative weekly variations based on Thursday market closes, while the Direção-Geral de Energia e Geologia (DGEG) tracks baseline metrics for pump rates.
Market Factors and Where to Find the Best Rates
The weekly pricing projections are calculated using raw material costs established during market closures. As outlined by the Automóvel Clube de Portugal, the forecast consists of average values based on raw material prices at the close of the markets last Thursday, meaning final figures remain subject to last-minute crude fluctuations and Friday market settlements.
Beyond international commodities, actual prices paid at the pump depend heavily on individual brand pricing policies and geographic locations, as fuel pricing is fully liberalized across the country, meaning each brand and service station can apply its own values. Furthermore, potential government adjustments to the Imposto sobre Produtos Petrolíferos (ISP) by the Government could alter these expected figures before they take effect as noted in market tracking data by the Contas Poupança platform and ECO.
Consumers looking to minimize costs can consult the official fuel price comparison tool provided by the Direção-Geral de Energia e Geologia (DGEG) to locate the most affordable stations in their local area.
