How many miles do tractor trailers get per gallon?
Tractor-trailers typically get between 5 to 8 miles per gallon (MPG). This number can vary depending on several factors, including the size and weight of the truck, the type of engine, and the fuel used.
For example, smaller tractor-trailers that weigh less and have more efficient engines can get up to 10 MPG, while larger trucks might only get 4 MPG. Additionally, trucks that use diesel fuel tend to get better mileage than those that use gasoline.
