BALTIMORE (AP) — AAA says a switch to less expensive winter-blend gasoline should bring some relief to drivers for the second half of September.

The auto club says the switch to cheaper fuel is scheduled for Monday. Ahead of the change, the national average for a gallon of unleaded gasoline was $3.41 on Friday. That’s down 3 cents from the previous week.
