UPDATED--The cost of diesel in the United States has moved lower for the fourth straight week.

A new report from the U.S. Energy Department's Energy Information Administration shows the national average has fallen 2.2 cents from a week ago to $3.897 per gallon. It is down 8.4 cents before this most recent string of declines and 19.7 cents less than where it was a year ago.

Prices fell in all regions of the country with the biggest over the past week being recorded in the Central Atlantic sub region of the East Coast, losing 3 cents, for an average of $3.967 per gallon.

Diesel ranges from a low of $3.805 in the Gulf Coast region, down 2.6 cents from a week ago, to a high of $4.052 in the West Coast region, a decline of 2.3 cents during the same time.

Gasoline also continued it recent decline, shedding another 5.8 cents this week from the week before, for a U.S. average of $3.367 per gallon, down 48.3 cents from a year ago.

It ranges from a low of $3.127 in the Gulf Coast region to a high of $3.737 per gallon in the West Coast Region.

The reports came despite the partial federal government shutdown and there is no guarantee that they will be available in future weeks should the impasse over the budget continue.

Meantime, crude on Monday fell 81 cents in New York, closing at $103.03 per barrel, which is up about 70 cents from the same time a week ago. Last week it posted a slight gain after four straight weekly losses. Monday’s drop was attributed to oil production going back on the line in the Gulf of Mexico after it was shut down due to a tropical storm.

Update adds gasoline prices.
