Posted on Jun 06, 2010Consumers do not get the gallon of gas that they pay for when gasoline is stored at more than 60 degrees. Gasoline stored at over 60 degrees and loses energy, requiring that the volume sold the customer be increased. Gas over 60 degrees is known as hot fuel. A study by the Kansas City Sar determined that consumers are cheated out of up to $2.3 billion annually by the "hot fuel" practice. The defendants in the consumer class action lawsuit areBP, Casey's General Stores, Chevron, Circle K, Citgo, ConocoPhillips, 7-Eleven, Shell Oil, Valero, Kum & Go, QuikTrip and Wal-Mart.
