Diesel and gas prices rise again as summer nears

March 25, 2025
Diesel and gas prices rose this week to $3.567 and $3.115, respectively. Pump prices remain lower than a year ago, but refinery switches push up fuel prices.

After weeks of softening diesel and gas prices, the pendulum is swinging the other way. The national average on-highway diesel price rose by 2 cents to $3.567, according to data released by the U.S. Energy Information Administration on March 25. Gas prices are up 6 cents this week to $3.115. 

Here are this week’s diesel price highlights from each region of the U.S.:

  • Rocky Mountain: The Rockies saw the most significant increase in diesel prices this week of 4 cents to $3.415.
  • Midwest: The flyover states saw the next biggest diesel price increase of 3 cents to $3.491.
  • West Coast: Diesel prices rose by 3 cents off the West Coast, bringing the average to $4.229. Without factoring in California, diesel prices rose in the West by 4 cents to $3.754. 
  • Gulf Coast: Diesel prices off the Gulf rose by 2 cents to $3.265. 
  • East Coast: The East was the only part of the U.S. to see a drop in diesel prices this week. Prices dropped by 0.4 cents to $3.675.

AAA Motor Club reports that the national diesel price average is $3.584, 2 cents higher than EIA’s calculations. According to AAA, this average is 1 cent lower than last week and 50 cents lower than this time last year.

  • Midwest: This week, the Midwest saw the biggest rise in gas prices, with prices increasing by 13 cents to $3.020.

According to AAA, the current national gasoline price average is $3.128, 1.3 cents higher than EIA’s estimate. By AAA’s calculations, gas prices compared to this time last year are down by 41 cents. 

AAA reports in a press release that part of this upswing in gas prices is due to refineries switching to summer-blend gasoline, which is more expensive to create.
