On average, a semi truck can have a fuel tank capacity ranging from 200 to 500 gallons. Assuming a fuel tank capacity of 250 gallons and an average fuel efficiency of 6 miles per gallon, and a diesel price of $5.00 per gallon, it would cost approximately $2,083 to fill up the tank.
It's important to note that these figures are just estimates and can fluctuate based on real-time fuel prices and other variables.
