The FSC listed is the percentage of the gross freight rate.  We at Sun Coast Carriers decided that this method better assists us and most importantly, our customers.  This gives both parties more flexibility to respond to the weekly changes of fuel prices in the marketplace.                                     

The National Average price per gallon is obtained from The U.S. Dept. of Energy fuel price index:
