How far can a semi-truck travel with its tank full?

This article discusses how far a semi truck can travel on a full tank of gas.

Due to the average fuel efficiency of current trucks, which is approximately 7 miles per gallon,

a vehicle with twin fuel tanks can travel approximately 2,100 miles on a full tank.

There is enough gasoline to support the truck's entire weight with a 150 gallon fuel tank capacity for the majority of new Freightliner trucks and a 100 gallon tank for the tractor.

The tank, which is mounted on the truck's side, holds enough fuel to support the tractor's weight.

This type of semi-truck can travel up to 1,400 miles on a full tank before needing to refuel.
