UPDATED--The average cost of diesel in the United States has increased, putting it just below where it was four weeks ago.

The U.S. Energy Department reports it has gained 1.3 cents, registering $3.913 per gallon.

Compared to the same time a year ago the current price is 17.6 cents lower.

Prices increased in every region of the country, with the largest being seen in the Midwest, where it added 1.6 cents, for an average of $3.884.

Diesel ranges between a low of $3.829 in the Gulf Coast region, up 0.7 cents over the past week, to a high of $4.072, in the West Coast part of the country, up 1.5 cents during the same time. California’s average price is even higher at $4.156, up 2.2 cents.

As for gasoline, it turned slightly higher, following four consecutive weeks of decreases, increasing 0.2 cents over the past week for an average of $3.552 per gallon. Before the series of drops it stood at $3.682 per gallon.

Over the past week prices increased on the Lower Atlantic, Gulf Coast and Midwest parts, but fell in all other regions of the country.

Gasoline ranges between a low of $3.382, in the Gulf Coast region, up 0.9 cents over the past week, to a high of $3.745 in the West Coast region, down 3.3 cents during the same time.

This came as crude oil on Monday fell 50 cents by the close of trading in New York, settling at $105.92 per barrel. Over the past week it has fallen just over a dollar. The Monday drop came following a report that U.S. durable goods orders and shipments fell in July, despite the prospect of U.S. military intervention over Syria and news that it used chemical weapons.
