A Popular Gas Price Website Predicts Gas Prices Will Go Up 15 Cents Per Gallon In The Next Few Weeks

“I don’t think we’re necessarily looking at the fuel apocalypse,” said Tom Kloza, global head of energy analysis with the Oil Price Information Service. “But we’re in for a few months of higher prices.” Gasoline prices stood at an average of $3.819 a gallon in the Chicago metro area Thursday, up from $3.558 a month ago, according to AAA.
