The average U.S. price of a gallon of diesel fuel rose 3.5 cents a gallon last week to $3.683, the first increase in three months, the U.S. Department of Energy reported to NASSTRAC earlier this week. Shippers continually watch the volatility of prices as it can have a significant impact on overall supply chain costs.
Diesel had declined 50 cents a gallon since April 9 before the increase, DOE said after its July 9 survey of fueling stations. DOE also said the average retail gasoline price jumped 5.5 cents to $3.411 a gallon, the first increase in that average in 13 weeks. Gasoline had fallen 53 cents since April 2 before the jump. Following last week's increases, diesel now costs 21.6 cents a gallon less than it did a year ago and gasoline is 23 cents cheaper than the corresponding week in 2011.
