How to use this data
Use the current regional diesel price to calculate whether a carrier's fuel surcharge request is reasonable. Industry standard is to calculate surcharges from a base price of $1.20/gal at 6.5 MPG. If a carrier is charging significantly more than the calculator shows, ask them to justify the difference.
