Diesel fuel costs rose for the seventh consecutive week, but the uptick was relatively small, with a national increase of just 1.7 cents per gallon. This data comes from the Energy Information Administration’s report released on September 5th.

As of September 4th, the average diesel price across the nation reached $4.492 per gallon, representing a decrease of 59.2 cents per gallon compared to the same time last year.

Highlights:

  • The average price dropped in three regions: Lower Atlantic (1 cent), Midwest (0.2 cent) and East Coast (0.1 cent).
  • It rose in the other seven regions, led by a 12.3-cent surge in California, where diesel is now all the way back up to $5.801 a gallon.
  • Diesel remains cheapest in the Gulf Coast region at $4.171 a gallon.
  • Gasoline shifted slightly upward as well, rising 0.6 cent to $3.807 a gallon for the national average, which is 6.1 cents a gallon more than a year ago.
