What is U Haul 15 Foot Truck Gas Tank Size Capacity?

What is Uhaul 10 Foot Truck MPG and Estimation?

Vehicles differ in the way they use fuel to power their engine.

Trucks, for instance, are known to use more fuel than smaller cars for the same distance.

There are several reasons for this, but the most obvious one is their heavily-built frame. 

As a result, you should seriously consider gas mileage whenever you have to rent a moving truck, especially now that the average cost of gasoline nationwide is somewhere between $3.8 and $4.

So, when drawing up the budget for your next move, make sure you weigh the fuel mileage of your intended moving truck and how much it will cost you to pump the tank full.

By doing this, you will get a more comprehensive grasp of your overall cost. 

In this article, we will be tailoring the discussion to cover only the fuel mileage of the 15-foot U-Haul truck, from what it is to how much it will cost you to fill it up.

Some frequently asked questions will also be answered. But first, what do we mean by gas mileage?

The Meaning of Gas Mileage

Simply put, gas mileage is the miles a truck or any other vehicle can cover on one gallon of fuel.

It’s good and considered economical for a truck to have a high fuel mileage.

It means that your moving truck consumes little fuel to travel long distances per mile. 

Gas mileage is generally noted in MPG, which stands for miles per gallon.

That is to say that if your truck racks up a gas mileage of 11 mpg, it would mean that it travels 11 miles for every gallon of fuel. 

As a rule, the mpg of vehicles is typically lower within the city than on the highway.

The reason is simple: driving in the city requires lower speeds and idling, but a higher rpm (revolutions per minute).

What is Uhaul 15 foot truck gas tank size?

The moving truck packs a 40-gallon fuel tank capacity. 

How much does it cost to fill up a 15 U-Haul?

The average gallon of gas in the country sells for $3.85 and a 15-foot U-Haul truck packs a 40-gallon fuel tank.

Doing the maths of multiplying the average fuel cost ($3.85) by the fuel tank capacity of the moving truck (40 gallons), the cost of filling up your truck’s tank will come up to about $154. 

The gas mileage of 15 foot U-Haul

Packing an impressive 40-gallon fuel tank size, the 15-foot U-Haul moving truck has an average fuel mileage of 10 MPG. A full tank will typically take you for 400 miles. 

How to calculate gas mileage 

Many of the modern-day vehicles come fitted with digital screens that display real-time gas mileage numbers.

This is really state-of-the-art and helpful, but most vehicles, especially trucks, don’t have it.

For these vehicles, you will have to manually calculate them. 

Using the 15-foot U-Haul moving truck, here’s a step by step guide on how to calculate: 

  • Fill up the truck’s 40-gallon tank. 
  • Drive the truck for, let’s say, 100 miles. 
  • At the end of the drive, refill the used-up fuel. The refill quantity is the amount of fuel used, let’s say 10 gallons. 
  • Now, divide the number of miles traveled (100 miles) by the amount of fuel used for the drive (10). The fuel mileage will be 10 MPG.  

The importance of GM to renters

Before you rent a 15 foot moving from U-Haul, you must know just how much it will cost to fuel it.

And seeing as MPG is the globally accepted way of measuring fuel efficiency, it helps prepare you for what you can expect fuel-wise.

What’s more, it also allows you to be more responsible and careful while driving. 

Estimating MPG for a 15ft U-Haul

A 15-foot U-Haul moving truck has a fuel tank size capacity of 40 gallons. 

To estimate it, drive the truck for 100 miles on a full tank. Then, take note of the amount of gas used when refilling the tank.

Then divide the distance traveled (100 miles) by the amount of fuel used, which will be around 10 gallons. 

The fuel mileage should come to about 10 MPG. 

Factors that determine the gas mileage of a truck

As stated already in this article, gas mileage is measured in MPG.

Taking all other variables into consideration, the MPG helps you to measure the fuel efficiency/economy of your truck. 

The following are the main factors that can impact the truck’s gas mileage. 

Vehicle type

As a rule, vehicles with smaller engines have higher mileage than larger ones as a result of the vehicle’s mass.

Essentially, smaller engines make for lighter vehicles and require less fuel. As an example, a 10-foot U-Haul truck will have a better gas mileage than Toyota Rav4. 

Fuel type

The quality of the fuel that your vehicle runs on can impact the friction inside the engine of the vehicle, consequently affecting the gas mileage. 

Fuel octane rating

The octane rating of the fuel connotes how fast or slow the vehicle’s engine burns gas in regards to the fuel reduction to additive ratio.

If your fuel has a high octane rating, it means your engine will function efficiently and that extends to fuel economy. 

Driving conditions

As we have already established in this article, your truck gets a lower gas mileage on a city street than on the highway. The difference can be as high as three to five miles. 

Driving style

Generally, vehicles driven by aggressive, overspeeding drivers get worse fuel mileage when compared with those driven by more careful, slower drivers.

For instance, your vehicle burns more fuel when you accelerate suddenly from rest than when you go about it slowly. 


How many gallons of gas does a 15-foot U-Haul hold?

The moving truck will hold 40 gallons of gas at maximum capacity. 

Why does towing a vehicle increase fuel consumption?

Using your truck to tow another vehicle or a trailer requires force. The truck’s engine provides this force. The more the force, the more fuel it consumes. 

What kind of gas do you put in a 15-foot U-Haul truck?

All of the 40-gallon gas tank capacity of the moving truck runs on unleaded fuel. If the truck must function at maximum capacity, the fuel tank must be filled with the required fuel type. 

How much money would I spend on gas, driving a 15 foot U-Haul truck for 1300 miles?

Before you can get the cost of fuel for traveling 1,300 miles, you will first of all have to calculate how much fuel you would need.

Fuel gauge meterAnd going by the calculation already established in this article, 40 gallons of fuel will take your moving truck for 400 miles.

Fetching from this figure, it will take 130 gallons of fuel for your truck to drive for 1,300 miles.

To get the cost, simply multiply the amount of fuel needed (130 gallons) by the average cost of fuel ($3.85).

You will be spending $500.5 to drive a 15-foot UHaul truck for 1,300 miles. 


There you go, everything you need to know about the fuel mileage of a 15-foot moving truck from U-Haul.
