The lowest average was found in the Gulf Coast, although prices there actually rose about a penny to $2.859 per gallon.
Closest to that was the Lower Atlantic region at $2.867 per gallon. The Central Atlantic saw a slight drop to $2.990 per gallon, while the New England Region came in at $2.960 per gallon, down nearly 2 cents from the previous week.

The Midwest showed almost no change, coming in at $2.873 per gallon, down a fraction of a penny from the previous week.
