Most 26 ft box trucks average 6–10 miles per gallon (MPG), depending on factors like load weight, driving conditions, engine type, and maintenance.
- Diesel engines typically offer better fuel efficiency and durability for long-distance hauling
- Gas engines may have lower upfront costs but slightly higher fuel consumption
Fuel efficiency can vary significantly based on how the truck is used, but choosing the right engine and maintaining proper load management can help reduce operating costs over time.
