The average on-highway retail diesel price in the US rose by 1.9 cents to $4.142/gal the survey week ending Monday, the Energy Information Administration said.
The national average is 23.5 cents higher than the corresponding survey week a year ago.
The most recent higher price was the $4.145/gal average of August 25, 2008, according to Platts tracking of EIA data.
The largest climb among regional averages in the current weekly data was the 5-cent hike in the Rockies to $4.119/gal, the EIA data showed.
The West Coast showed the highest regional average of $4.431, up 1 cent.
The Midwest average saw a 2.4-cent uptick to $4.040/gal, the Gulf Coast average rose 1.7 cents to $4.053/gal and the East Coast average increased 1.5 cents to $4.184/gal.
EIA each week conducts a telephone, fax, email and web survey of retail on-highway diesel prices from a sample of about 400 truck stops and service stations around the US. The results are compiled into a US average price and average prices for eight regions of the country and California. The data represent the price of ultra low sulfur diesel, which contains less than 15 ppm sulfur, according to the EIA website.
