A reportagem do Terra comparou dados disponibilizados pela Agência Nacional do Petróleo (ANP) entre as semanas do dia 22 a 28 de fevereiro, período em que se iniciou o conflito, e 15 de março a 21 de março, segundo relatório da agência. Os valores consideram a média de revenda dos combustíveis.
Em duas semanas, a gasolina comum saiu de R$ 6,28 para R$ 6,65, variando em cerca de 5,9%. Já o diesel S10 saltou de R$ 6,09 para R$ 7,35, sofrendo variação de cerca de 20,7%.
O etanol hidratado variou 1,5%, saindo de R$ 4,63 para R$ 4,70, enquanto o GLP (gás de cozinha) aumentou alguns centavos, de R$ 109,87 para R$ 109,91, representando uma variação de 0,04%.
O Norte e o Nordeste lideram o ranking dos preços mais altos da gasolina comum. Nesta semana, o Acre, que está no topo do ranking, chegou ao preço de revenda de R$ 7,47, enquanto o Rio Grande do Norte bateu R$ 7,28.
O Acre também lidera o preço no diesel S10, com R$ 8,04, seguido da Bahia com R$ 7,90 e Roraima com R$ 7,66, de acordo com o relatório da ANP. No que se refere ao etanol hidratado, o Rio Grande do Norte tem o preço de revenda mais caro esta semana, com R$ 5,89, seguido de Pernambuco com R$ 5,77. Já o GLP chegou a R$ 141,72 em Roraima e a R$ 128,95 no Tocantins.
