“Seasonal factors, as expected, are pushing gas prices down in most areas across the country,” said Patrick De Haan, head of petroleum analysis for GasBuddy. “In addition, oil prices have hit a rough patch on renewed concerns about the economy and falling demand, leaving motorists the beneficiaries for the next few weeks. No one should be in a rush to fill up as prices will likely continue to trend lower.”
