"We've seen the national average fade slightly again as oil prices have cooled and our spring peak appears to be more confidently behind us," said Patrick De Haan, head of petroleum analysis at GasBuddy. "While refinery utilization rates last week indicated that there is still some refinery maintenance work to be done, oil prices have helped put downward pressure on gasoline prices, with oil falling below $80 per barrel last week. In addition, a weaker than expected jobs report is adding to some concerns that gasoline demand could remain weak through the summer driving season, which is just a few weeks from beginning. With the seasonal factors behind us, looking ahead, we expect gasoline prices to continue cooling alongside diesel prices as we look forward to Memorial Day weekend."
