We at Mammoth Ready Mix appreciate your business and understand that high fuel costs affect your business in many negative ways. We have avoided passing these increased costs onto you, our customer, but at these new record highs, we are unable to absorb these costs any longer. We appreciate your understanding of this matter and stand ready to assist you on your project in any way we can.

The Fuel Surcharge is based on The Department of Energy price index for California U.S. On-Highway Diesel Fuel Prices which can be found at www.eia.gov/petroleum/gasdiesel.

The fuel surcharge will be indexed weekly from a base of $3.00/gal. Each Monday, the average of the previous week’s fuel cost will be used to calculate the current week's fuel surcharge. For every $0.05 in the fuel index over the $3.00 base price we will charge a surcharge of $0.125/CY. This fuel index will be updated and posted here with the fuel surcharge rate for the current week.
