The U.S. average price for on-highway diesel continued its downward momentum in the week ended Nov. 11, falling another 2.5 cents and reaching another four-month low — $3.832, according to the Department of Energy’s Energy Information Administration.
The average price now has seen a week-to-week increase since the week ended Sept. 9, after a brief spike that came on the heels of increased likelihood of U.S. intervention in Syria.
The price has since fallen 14.9 cents in the 10 weeks following.
ProMiles’ Fuel Surcharge Index also reported a 2.5-cent drop in the national average on-highway price. Its national average is a little cheaper than the EIA’s, $3.775.
The EIA’s price is down 14.8 cents from the same week in 2012, and the Fuel Surcharge Index’s is 15.2 cents cheaper.
All regions in the U.S. saw price decreases, according to both EIA and the FSI, led by a 4.2-cent drop in the West Coast less California region, according to EIA.
Moreover, all regions now have average prices lower than $4, save for California, reports EIA, which has an average price of $4.055. The Gulf Coast region still has the nation’s cheapest diesel, $3.752.
