Source and method
Prices are reported by station operators to Monitorul Prețurilor Carburanților (Consiliul Concurenței). We collect them every two hours and calculate the averages in this article ourselves. The national average is the unweighted mean of the 1,130 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.
