How Many Gallons of Fuel Would the Rental Car Consume per Mile?

When you’re looking to rent a car, it’s important to consider how many gallons of fuel the rental car will consume per mile. This information can help you make an informed decision about which rental car is the best for your needs.

What is Fuel Economy?

Fuel economy is the average distance a vehicle can travel per gallon of fuel. The higher the fuel economy, the better. In order to get high fuel economy, a car must have efficient engines and aerodynamic design.

The calculation of fuel economy is not simple. It varies depending on factors like weight, speed, load, and type of driving. However, one common measure is miles per gallon (MPG).

There are many factors that affect MPG. Weight and speed are two major ones. Vehicles with larger engines tend to have higher MPG ratings because they can travel further on a given amount of fuel. Aerodynamics also play a role in MPG ratings; a streamlined design means less drag on the engine, reducing gas consumption.

All things being equal, a vehicle with an MPG rating of 30 will travel 30% farther than one with an MPG rating of 20. But all things aren’t always equal: A heavier car will have more inertia and take longer to reach speeds where its engine can produce more power, meaning it will consume more fuel while cruising at lower speeds than a lighter car would.

How to Calculate Fuel Economy in Miles per Gallon

There is no one-size-fits-all answer to this question, as the fuel economy of a rental car will vary depending on the make and model of the vehicle, the driving habits of the rental car driver, and the terrain that they are travelling over. However, some ballpark figures that can be used to calculate fuel economy in miles per gallon for a rental car are as follows:

A compact car like a Toyota Yaris typically averages around 22 mpg in the city and 30 mpg on the highway. A larger sedan like a Honda Accord can get up to 37 mpg on the highway. Note that these are average figures; your mileage may vary depending on your specific driving habits and route.

If you’re planning on renting a car for a long weekend trip, it’s usually a good idea to double or triple these numbers to account for variable speeds, hills, and other factors.

What Factors Affect Fuel Economy?

There are a number of factors that affect fuel economy in a car. The type of fuel used, the size and weight of the vehicle, and how the car is driven all play a role. Here are some common factors that affect fuel economy:

-The type of fuel used: Different fuels have different combustion characteristics, which can affect fuel economy. Gasoline has a higher octane rating than diesel or ethanol, for example, which can lead to higher performance but also higher emissions. In general, using the lowest-emitting fuel available is usually the best way to save on fuel costs.

-The size and weight of the vehicle: Larger vehicles use more fuel per mile due to their greater mass and faster speeds. Additionally, larger vehicles tend to require more frequent gear changes, which uses more gas. Smaller cars and hybrids typically use less gas per mile than large cars because they weigh less and have smaller engines.

-How the car is driven: Driving habits such as speeding, braking hard, and making abrupt turns all use more gas than normal driving. Taking your time and avoiding unnecessary stops can save you money on your gasoline bill.

The Rental Car Fuel Consumption Formula

The average rental car consumes around 12 gallons of fuel per mile. This means that if you drive your rental car 5,000 miles, you would use up around 60 gallons of gasoline. So it’s important to be mindful of how much fuel you’re using and to make sure you have enough fuel to get you where you’re going!


In order to answer this question, we first need to establish what a mile is. A mile is about 1.6 kilometers, so if we take the average fuel consumption for a rental car in the U.S., it would be around 19 gallons per mile. Therefore, our rental car would consume about 59 gallons of fuel in one full day! That might not seem like much, but over the course of a month that adds up quickly!
