How far can a semi-truck travel on a full tank?

This article discusses the distance a semi-truck can travel with a full fuel tank.

Considering that the average fuel economy for new trucks is approximately 7 miles per gallon,

a truck with two fuel tanks can travel approximately 2,100 miles on a single tank.

 Most new Freightliner trucks have a 150-gallon fuel tank and a 100-gallon fuel tank for the tractor,

which is sufficient to cover the truck's total weight. The tank sits on the side of the truck and contains sufficient fuel to help maintain the tractor's equilibrium.

On a full tank, this type of semi-truck can travel up to 1,400 miles before refuelling.

Modern trucks may be able to travel farther due to their improved fuel efficiency, but they must all refuel at some point.
