"With another drop in the national average from a week ago, we've made it eight straight weeks of decline, and for the first time in GasBuddy's 20 year history, we have two cities that are averaging under $1 per gallon. That's right — not a single station under $1, but the entire city average,“ said Patrick DeHaan, head of petroleum analysis for GasBuddy. ”Truly unprecedented demand destruction has been dismantling expensive gas prices everywhere.

"With oil again at new multi-decade lows, we still have room for prices to fall nearly countrywide, though areas with lower prices will see little decline — take Wisconsin for example, while higher priced states like California have the most room to decline. With the wounds to the oil industry growing deeper, it's becoming more likely that even after most Americans return to work, there will be a hangover to the low prices that many motorists will eventually be able to take advantage of."
