The fuel mileage of a 7.3L diesel engine, commonly found in Ford Super Duty trucks from the late 1990s to early 2000s, typically ranges from 12 to 18 miles per gallon (MPG), depending on factors like load, driving conditions, and maintenance. In highway driving conditions, many owners report achieving closer to 18 MPG, while city driving may yield lower figures. Performance can also be influenced by modifications and the specific vehicle configuration. Overall, the 7.3L diesel is known for its durability and fuel efficiency relative to its size and power.

Better mileage
Probably the best way to get better fuel mileage would be to get a tuner for it.

Diesel will always give you better fuel mileage as diesel fuel itself contains more BTU (the measure of thermal energy) in a given quantity than compared to gas.So therefore a diesel engine can extract more mileage out of a gallon of diesel fuel as there is more energy to extract out of that gallon as compared to a gallon of gas.Considering this, this is why diesel fuel prices would have to rise considerably over gas before the two would be equal on a cost per mile basis.
Keeping up with scheduled maintenance, better driving habits... a lot's been done since ACERT went into effect in the early 2000s which has impaired fuel mileage... EGRs decreased fuel mileage, SCR/DPF/DEF decreases fuel mileage, 2007 introduced Ultra Low Sulphur Diesel - which is a less efficient fuel than the previous low sulphur diese - all in the name of emissions. Turbocharging remains the best option to improve diesel efficiency.
Diesel engines normally get better fuel economy than gasoline engines.
That depends on your fuel mileage.
No one truck, no one answer. It will depend on the fuel mileage for the truck in question.
No, you cannot put regular fuel into a diesel engine, because the two fuels burn at different temperatures. You can try cleaning your engine, they make products to remove buildup, and this will help your mileage.
miles/gallons in tank= milage
Yes, diesel engines traditionally get better fuel mileage than a gasoline engine.
