Diesel stands at $5.652 a gallon on August 24, 2026 — the highest reading in the 2-year archive, which reaches back to September 25, 2023. A 500-mile truckload burns about 77 gallons — $434.77 of fuel per lane at this price.

The archive has run from $3.451 a gallon (June 2, 2025) to $5.652 a gallon (August 24, 2026); this print sits at the 100th percentile of that band, with no higher reading anywhere in it. The standing trend is rising.

The archive starts September 25, 2023, so "highest in the archive" is a statement about those 2 years — not about all time, which the archive cannot see. Source: EIA Gasoline and Diesel Fuel Update, weekly.
