The national average price for a gallon of on-highway diesel fell again in the week ended Nov. 4, dropping 1.3 cents to $3.857, according to the Department of Energy’s Energy Information Administration.
The week-to-week drop continues a near two-month long drop in the on-highway price of diesel, as the average price has fallen every week since the week ended Sept. 16, save for the week ended Oct. 21, which saw no week-to-week change in the price of diesel. The national average price has fallen 12.4 cents in that time frame.
The average price hasn’t risen since the week ended Sept. 2, as there was no change in the price in the week ended Sept. 9.
The week’s price, according to EIA, was the lowest since the week ended July 8.
ProMiles’ Fuel Surcharge Index also reported a 1.3-cent drop in the week ended Nov. 4. It’s national average price, however, is more than a nickel lower than EIA’s — $3.80. ProMiles gathers its data from at-pump prices from thousands of truck stops nationwide.
Prices also dropped in all regions, according to the EIA, led by a 2.5-cent drop in California, which also still has the nation’s most expensive diesel, $4.092 a gallon.
ProMiles also reported that the average price in all regions dropped, led by a 2.9-cent increase in California, which, in its data, is the only region with an average price higher than $4 — $4.055.
The Gulf Coast region has the country’s cheapest diesel, $3.744 a gallon, according to ProMiles, and $3.769, according to the EIA.
All prices are well below the average prices reported for the same week in 2012.
