The national mean diesel fuel cost dropped by a similar margin as its recent uptick, decreasing by 9.1 cents to reach $4.454 per gallon, as reported in the Energy Information Administration’s data released on October 30th.

Following a recent 10.1-cent increase, diesel prices have now taken a dip, largely stemming from a 25-cent spike in the Midwest due to issues in the extensive 9,800-mile-long Magellan Pipeline system. Currently, a gallon of diesel, the primary fuel for trucking, costs 86.3 cents less than it did at the same time last year.

In the Energy Information Administration’s weekly survey, the average diesel price decreased in all 10 regions, with five regions experiencing substantial double-digit drops, led by California with a decrease of 12.6 cents, bringing the average price per gallon in the state to below $6, specifically at $5.890. The most modest decline was 1.4 cents in New England.

Additionally, gasoline prices also decreased, dropping by a uniform 6 cents per gallon nationwide, resulting in an average price of $3.473 per gallon.
