"We're watching an incredible decline in the price of crude oil and gasoline futures that will most certainly have an impact in the upcoming week at the pump. While motorists won't see large drops all at once, I most certainly expect declines in the days ahead," says Patrick DeHaan, GasBuddy.com Senior Petroleum Analyst. "Oil prices have shed nearly $15 per barrel in just a week- a dramatic decline brought on by various concerns, but mainly a weak manufacturing report and concern surrounding a possible downgrade of U.S. credit ratings," DeHaan adds.
