How much fuel does a diesel truck generally take?

Diesel trucks have varying fuel capacities depending on the size and make of the vehicle. On average, a standard full-size diesel pickup truck can have a fuel tank capacity ranging from 25 to 35 gallons. Heavy-duty diesel trucks, such as those used for commercial purposes or long-haul transportation, can have fuel tanks that hold anywhere from 50 to over 100 gallons of diesel fuel. The specific fuel capacity of a diesel truck can be found in the owner's manual or by checking the manufacturer's specifications for the particular vehicle.
