Diesel prices, boosted by record-setting highs in crude oil prices and scattered refinery outages during the peak summer season, did a 15.9-cent leapfrog over that old record last week to set the new standard at $2.567.
The West Coast and California regions, which had been hit with skyrocketing fuel prices over the past month, were spared the worst of the increases, rising 9 and 9.9 cents, respectively, to $2.891 and $3.042.
Crude oil rose 7.3% last week, marking the biggest weekly price jump in nearly two months.
The Midwest experienced the largest increase—18.8 cents to $2.524. The Gulf Coast has the cheapest diesel prices, despite a 15.8-cent jump to $2.481.
