Diesel and gas prices continue to climb at pumps across the U.S.

May 30, 2018
Diesel prices are up by an average of 72 cents per gallon compared to 2017; gasoline is up 56 cents year-over-year, according to Energy Information Administration.

Prices at the pump continue to creep higher across the nation for both retail diesel and gasoline prices, according to data tracked by the Energy Information Administration (EIA). California, far ahead of the rest of the nation, is now just 0.3 cents away from averaging $4 per gallon of diesel. It is the only state where diesel customers are paying a dollar more than they were a year ago.

For the third week in a row, the national average for diesel was higher than the previous week: up 1.1 cent per gallon to $3.288 on Memorial Day, Monday, May 28. Every region in the nation but the Gulf Coast saw week-over-week diesel prices rise, according to data released by the EIA on Tuesday night. And the Gulf Coast only saw a 0.1 cent per gallon reduction in diesel prices.

Monday's U.S. diesel prices were 71.7 cents more than the same week a year ago thanks to a wide range of increases across the nation: From a 63.1-cent increase in the Gulf Coast to a $1.066 year-over-year increase in California. The West Coast region is up 94.1 cents compared to this week last year (77.9 cents if you don't count California). The Midwest is the only other region to outpace the national average increase in diesel with a 71.8 cent per gallon year-over-year increase.

The West Coast is home to the most expensive average diesel per gallon at $3.784 (mostly thanks to California's $3.997 average per gallon); while the Gulf Coast has the lowest price per gallon ($3.054).

Here is a look at the week-over-week diesel prices in every region of the U.S., as EIA reported on Tuesday:

  • East Coast:$3.287 (up 1.1¢)
    • New England:$3.307 (up 2.5¢)
    • Central Atlantic:$3.443 (up 2.3¢)
    • Lower Atlantic:$3.174 ( up 1.1¢)
  • Midwest:$3.230 (up 1.2¢)
  • Gulf Coast:$3.054 (down 0.01¢)
  • Rocky Mountain:$3.353 (up 0.5¢)
  • West Coast:$3.784 (up 1.9¢)
    • West Coast less California:$3.514 (up 1.1¢)
    • California:$3.997 (up 2.4¢)

Retail gasoline averages at the pump are nearing a national average of $3 per gallon this week, according to EIA. The U.S. gasoline average was up 3.9 cents per gallon to $2.962. That is a 55.6 cent per gallon increase compared to this week in 2017.

The biggest gasoline increase by region came in the Lower Atlantic states, which saw a 6.7 cent increase to $2.818 per gallon. The Rocky Mountain states ($2.991 per gallon) saw the smallest increase (2.3 cents) this week.

Just like with diesel, the West Coast is home to the most expensive average gasoline per gallon at $3.463 (mostly thanks to California's $3.636 average per gallon); while the Gulf Coast has the lowest price per gallon of gasoline ($2.721).

Here's a look at gasoline prices per gallon by region and how they changed this week:

  • East Coast:$2.910 (up 5¢)
    • New England:$2.980 (up 3.5¢)
    • Central Atlantic:$3.027 (up 3¢)
    • Lower Atlantic:$2.818 (up 6.7¢)
  • Midwest:$2.881 (up 3¢)
  • Gulf Coast:$2.721 (up 4.5¢)
  • Rocky Mountain:$2.991 (up 2.3¢)
  • West Coast:$3.463 (up 2.8¢)
    • West Coast less California:$3.463 (up 2.8¢)
    • California:$3.636 (up 1.8¢)
