National on-highway diesel dropped five tenths of a cent Monday to $3.853 a gallon compared to last week’s $3.858 average, the Energy Information Administration (EIA) of the U.S. Energy Department reported.
Only one reporting region, West Coast less California, showed a price increase. Truckers in that area are now paying two tenths of a penny more or $3.930 compared with the July 28 price of $3.928.
Diesel is still above the $4-a-gallon threshold in three regions: California, at $4.087 a gallon; the West Coast at $4.016; and New England at $4.019.
Crude oil accounts for 63 percent of the cost of a gallon of diesel, while 14 percent of the cost is for distribution and marketing, 13 percent goes to pay taxes and 10 percent is for refining.
In the Lower Atlantic region diesel stayed the same as what it had been July 28, $3.187.
On March 24 national diesel went below $4 a gallon and has stayed below $4 ever since. But that could change, depending on oil prices.
