The average price for diesel fuel in the U.S. dropped almost six cents this week, falling to $3.897 per gallon compared to $3.956 last week and $4.004 per gallon during the week of May 14, according to data tracked by the U.S. Energy Information Administration (EIA).
However, the agency also expressed concern in a recent brief over the growing lack of spare petroleum production capacity controlled by Organization of the Petroleum Exporting Countries (OPEC), which could potentially contribute to another spike in fuel prices both in the U.S. and worldwide in the near future.
Diesel prices dropped in every major region of the country, EIA said, with the cost per gallon now over four dollars in only three areas: New England ($4.072), the Central Atlantic ($4.023), the West Coast ($4.164), and California ($4.228).
