On-highway diesel (HDF) reference used this cycle: $5.4620/gal. Mileage-based programs multiply these factors by the miles your car runs, so a 45¢/mile factor on a 1,500-mile move is roughly $675 per car.

How to read this. Most Class I fuel surcharges are mileage-based: a cents-per-mile factor that resets monthly against the average on-highway diesel price two months prior. Programs differ by strike price, rounding, and whether your traffic moves under public tariff or contract, which is why several carriers below show more than one factor. Where a row is marked formula-derived, we calculate it from the carrier's published formula rather than reading a posted table — check the carrier source before you invoice against it. These figures are for planning; we do not guarantee rates.
