 Owner-operators are well advised, however, to pass up network fuel stops that are too costly, are too far off-route, sell inferior fuel, or are dangerously or poorly maintained. For independent owner-operators, a bevy of fuel discount networks exists, from a variety of traditional fuel cards to the National Association of Small Trucking Companies network and the younger mudflap applications discounts at independent truck stops around the nation. Research the options and discounts available to find the right one for you.
