Diesel Eases to $6.179: Why Your Cost per Mile Still Deserves a Fresh Look
The latest EIA weekly diesel benchmark fell two cents, but regional differences still matter. Here is how to translate the report into a load-planning number.
A small national decline, a different story by region
The EIA release dated October 14 reports a U.S. on-highway diesel average of $6.179 per gallon for October 12, down from $6.199 the previous week. These are weekly survey estimates including taxes—not a quote for the next truck stop on your route. The same table shows $5.809 for the Gulf Coast and $7.240 for the West Coast. California is listed at $8.091. A national decline therefore does not mean every driver's local price declined: the Rocky Mountain and West Coast figures rose in the latest comparison.
Put the price into the load calculation
Illustrative calculation: a truck averaging 6.5 miles per gallon would spend about 95.1 cents per mile on diesel at $6.179 a gallon. Across 1,000 total miles, that is approximately $951 in fuel alone. This example assumes the same price and fuel economy for the entire trip; it excludes DEF, idling differences, maintenance and other operating costs. The two-cent weekly price decline would reduce that example's fuel bill by only about $3.08. That is useful context when someone points to falling diesel as a reason to overlook a weak rate.
The Highway Hobo takeaway
Before accepting a load, use total miles, including repositioning, and your own recent fuel economy. Compare actual available pump prices after applicable discounts. If a fuel surcharge is part of the agreement, check which index and date the contract uses rather than assuming the newest national number automatically applies. Record your estimated fuel spend next to the actual receipts after delivery. The gap tells you whether the planning assumption needs adjustment. A benchmark is a starting point; the route and the truck decide the real bill.
