What is the gas mileage of a U-Haul® Rental Truck?

U-Haul® Truck gas mileage

One of the most common questions people have with a U-Haul rental is the fuel usage. Compared to a personal vehicle, trucks get poor gas mileage — but what MPG do they actually get? Each truck gets different gas mileage, and several factors can play a role in the actual fuel efficiency (towing, driving habits, etc.). And since fuel costs aren’t included in the rental fee, it can be a big concern. Find out the gas mileage of each truck, along with some factors that may also play a role in fuel use during a move.

The gas mileage of each U-Haul truck size

U-Haul trucks come in five different sizes: 10’, 15’, 17’, 20’ and 26’. A typical U-Haul gets around 10 miles per gallon, but each truck gets different exact mileage. And as you would expect, as truck size increases, fuel efficiency decreases. That means the bigger the truck, the higher the fuel costs. The chart below shows the average miles per gallon (according to U-Haul), the tank size and miles per fuel tank for each truck.

Note: Listed MPG and miles per fuel tank are estimated for empty trucks. A fully loaded U-Haul truck may not be as fuel efficient.


Here’s an example of how we did the “miles per fuel tank” math: 
With a rental truck that has a 57-gallon gas tank and gets 9 mpg, you could expect to fill up the loaded U-Haul every 513 miles (9 mpg x 57-gallon tank = 513 miles per tank). 

10-foot truck

The 10-foot U-Haul gets 12 miles per gallon, with a 31-gallon tank (using unleaded fuel). The whole tank will provide 372 miles of driving.

15-foot truck

The 15-foot U-Haul gets 10 miles per gallon.  It has a 40-gallon tank (using unleaded fuel).  The trip distance of one entire tank is 400 miles. 

17-foot truck

The 17-foot U-Haul gets 10 miles per gallon, with a 40-gallon tank (using unleaded fuel). One full fuel tank will give you 400 miles of travel.

20-foot truck

The 20-foot U-Haul gets 10 miles per gallon. The 40-gallon fuel tank (using unleaded fuel) will provide 400 miles of driving distance.

26-foot truck

The 26-foot U-Haul gets 10 miles per gallon with a 60-gallon fuel tank (using unleaded fuel).  One entire tank will take you 600 miles.

Other things that affect gas mileage in a U-Haul

As noted above, the fuel usage estimates are for empty trucks, so a loaded truck will likely use more gas. Other factors can influence the MPG you get in a U-Haul, including:

  • Towing. The added weight of a tow trailer decreases U-Haul gas mileage because it takes more power to move a heavier load. If you plan on towing a trailer or car carrier behind your truck, expect to see lower gas mileage and higher fuel costs.
  • Driving style. Quick acceleration, heavy braking, using the heater or air conditioner, and other driving habits can cause a decrease in fuel efficiency.
  • Terrain. Depending on where you’re driving to and from, mountainous areas can reduce fuel economy, as the truck has to work harder to pull the load up hills.  
  • Vehicle maintenance. Poorly-tuned engines, dirty air filters, and under-inflated tires can lower fuel economy. Check with your U-Haul dealer to ensure the vehicle is in proper driving condition before hitting the road.
