“DIESEL EXHAUST FLUID” DEF
When purchasing def at the fuel stops the fuel card will only work at the pumps. YOU
CAN NOT purchase the gallon jugs with the fuel card. Marten does not want to buy the
gallon containers if all possible because the cost of a 2.5 gallon container will be around
$15.00 and the price we pay at the pump will between 2.30-2.70 a gallon. Always top off
you DEF tanks at the terminals that have it whenever possible because the price we pay
for DEF is about $1.00 per gallon cheaper.
