“The price of crude oil, which had been gaining steam leading up to June, has now experienced a sustained downturn over the last couple of weeks. As crude oil prices have cooled off, the impact is finally being felt in the retail gasoline sector, where the national average for gasoline fell over 5 cents per gallon in one week’s time,” said Will Speer, GasBuddy senior petroleum analyst. “No area has seen this impact more pronounced than the Great Lakes states, where Indiana and Ohio saw their gas prices fall over 15 cents per gallon in one week.”
