It’s the first time the price of diesel has dropped since June 3, as trucking’s main fuel had gained 32.4 cents over the prior three weeks thanks to rising tensions in the Middle East. After a one-week blip, the cost of a gallon of diesel again dipped below the year-ago level, at 8.6 cents less than the 2024 level.
