National average retail diesel fuel pricing starting out for Spring 2023 decreased across the board once again to $4.13 per gallon as of March 28, 2023, according to the U.S. Energy Information Administration (EIA). 

This average price represents a decrease of 6 cents per gallon compared to the prior week and a decrease of about $1.06 per gallon compared to one year prior. 

Digging into U.S. Regional Diesel Fuel Prices

All regions again saw a price decrease for diesel fuel week-over-week and year-over-year. West Coast average prices have remained below the $5 per gallon mark (except for California, which still averages $5.17 per gallon of diesel).

The biggest week-over-week decrease was seen in the Rocky Mountain region for a second consecutive week at almost 12 cents below last week. The highest year-over-year decrease was seen in the Gulf Coast yet again, dipping $1.03 below the same time last year. Currently, two regions have dipped below the $4 per gallon mark: the Midwest and Gulf Coast.

Current average diesel prices by region are:

  • East Coast: $4.13
  • Midwest: $3.97
  • Gulf Coast: $3.88
  • Rocky Mountain: $4.23
  • West Coast: $4.80

Why Should Fleet Managers Monitor Fuel Prices?

Knowing the average diesel prices for work truck fleet managers is crucial for effective fleet management. Diesel fuel prices can significantly impact a fleet's operating costs and the company's bottom line.

With constantly changing fuel prices, fleet managers must stay updated on the latest diesel prices to make informed decisions about fueling their vehicles. They need to know when, how much, and where to buy fuel to minimize costs and ensure their trucks remain operational.

By closely monitoring diesel prices and trends, fleet managers can develop and implement cost-effective strategies to optimize fuel efficiency, reduce expenses.
