“The national average price of gasoline has seen little overall change over the last week, with big decreases in states like Colorado and Ohio offset by large increases in Arizona and North Carolina. While more states saw declines than increases, any downward trends are still likely to be temporary and not necessarily long-lasting,” Patrick De Haan, head of petroleum analysis at GasBuddy said. “Motorists in some areas may be on the receiving end of good news, while others may not as we hit the second half of refinery maintenance season. You never know what the closing moments will look like, and motorists could be in for a dramatic ride if issues develop.”

The national average diesel price fell 5.9 cents in the last week and now stands at $4.19 per gallon.
