"As we welcome back winter gasoline across most of the country, gasoline production has continued to recover after Harvey, leading much of the country to enjoy falling gasoline prices along with fall weather," said Patrick DeHaan, senior petroleum analyst for GasBuddy. "With refineries continuing to get back online and with demand cooling off from the summer months, we have more room to see the national average drop in the week ahead. In fact, this week could see some of the largest drops in gas prices in many months. It still will take time to completely heal from the issues Harvey and Irma left, particularly due to the large scale disruptions of fuel logistics and production, but improvement will continue both with lower retail prices and high refinery output."
