“We continue to see the national average price of gasoline decline, now for the thirteenth straight week. But, we're seeing drastically different price behaviors from coast to coast, with some areas seeing noticeable increases while others are seeing decreases," said Patrick De Haan, head of petroleum analysis at GasBuddy. "Refinery issues in California are leading to increases in areas supplied by the state’s refineries, including areas of Arizona, Nevada, Oregon, Washington and of course, California. Gasoline supply remains tight for the East Coast with some modest moves up, while prices continue to edge lower in the Plains, South and areas of the Great Lakes. For now, I believe the drop in prices will overpower the increases, leading to potentially another decline this week, but we're in a very fragile time and certainly could see a broader move higher in the weeks ahead."
