Since diesel prices began their ascent in the middle of January, the national average diesel price has shot up 26 cents to $4.159 a gallon, marking the highest national average since Aug. 18, 2008, when diesel averaged $4.207 the previous week.
That year’s peak was at $4.764, coming during the week ended July 14, 2008.
Between Aug. 18, 2008, and this week, the national average price has flirted with the $4.15 mark, reaching that point exactly in October 2012. It didn’t breach it, though, until last week.
The good news, however, is that the climb seems to have slowed, as diesel rose just two-hundredths of a cent for the week ended Feb. 25 from the previous week, according to the U.S. Department of Energy’s Energy Information Administration.
Regionally, the Rocky Mountain Region had the nation’s cheapest average, $4.057, while California had the most expensive, $4.365.
