Source and method
Prices are reported by station operators to Preços dos Combustíveis Online (Direção-Geral de Energia e Geologia (DGEG)). We collect them once a day and calculate the averages in this article ourselves. The national average is the unweighted mean of the 3,253 stations that reported a valid price for petrol, 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.
