During the most recent week, prices fell in all regions except the Lower Atlantic and the West Coast less California regions, where prices held flat. The most significant decrease was seen in the Midwest, where diesel fell by 1.6 cents.

The most expensive fuel is in California, at an average of $3.885 per gallon, followed by the Central Atlantic region at $3.178 per gallon.

The cheapest diesel is in the Gulf Coast region at $2.74, followed by the Midwest and Lower Atlantic regions, both at $2.874 per gallon.
