Consumer protection agencies in Brazil have initiated investigations and surveys to monitor fluctuations in fuel costs. In Cuiabá, the Consumer Protection Agency (Procon) launched ‘Operação Ponto de Combustão’ to investigate 52 service stations. The operation aims to determine if recent price hikes for gasoline, diesel, and ethanol are justified by actual acquisition costs or if stations are making premature adjustments.

In the state of Paraíba, Procon surveys in João Pessoa and Campina Grande have tracked price variations. In João Pessoa, studies showed slight decreases in the lowest prices for ethanol and additive gasoline, alongside a drop in the maximum price for common gasoline. In Campina Grande, reports indicated a significant price spread for common gasoline, with an average price of R$ 6.37 and a difference of R$ 1.52 between the lowest and highest recorded prices.
