Important: These MPG and driving-range figures are estimates based on ideal conditions. Actual fuel economy may be lower when the truck is fully loaded, driven at higher speeds, traveling uphill, or operating in heavy traffic or bad weather. The truck model available at your rental location may also affect its dimensions and fuel performance.
How Much Gas Will a U-Haul Use?
To estimate how much fuel you may need for your move, divide the total driving distance by the truck’s estimated miles per gallon.
Estimated gallons needed = Total miles ÷ Estimated MPG
Example Fuel Calculation
A 600-mile trip in a 15-foot U-Haul truck rated at up to 10 MPG would require approximately 60 gallons of fuel under ideal conditions.
Budget tip: Allow room in your moving budget for additional fuel. A fully loaded truck may not achieve the highest advertised MPG.
