PIB TIP: FINDING THE CHEAPEST FUEL. The real cost of fuel is the pump price minus the taxes. There are ways to save money on both the fuel you buy and the fuel taxes you pay. Learn what your carrier’s fuel tax policy is, and find out which states have the best diesel prices. Daily fuel prices by lane and fuel tax listing are on eTrucker.com and in motor carrier atlases such as Rand McNally’s.
