Patrick De Haan, head of petroleum analysis at GasBuddy.com says the price of gasoline was driven up mainly by seasonal tightening and broader market dynamics.

He suggests the risk of broader instability means fresh uncertainty in the energy markets and gasoline prices will likely face continued upward pressure.
