Introduction to Toyota 4Runner Gas Mileage

The Toyota 4Runner is a mid-size SUV that has been produced by Toyota since 1984. Over the years, it has become a popular car both for off-road enthusiasts and families. Gas mileage is an essential factor to consider when purchasing a vehicle, and the 4Runner’s gas mileage varies depending on several factors, including the engine type and driving conditions. In this article, we will take a look at the Toyota 4Runner’s gas mileage and explore why it is crucial to consider for those looking to buy a car.

What is Toyota 4Runner?

The Toyota 4Runner is a mid-size SUV produced by Toyota since 1984. It has remained a popular vehicle due to its durability, reliability, and off-road prowess. Its current iteration comes with a standard V6 engine that produces 270 horsepower, while the optional V8 engine can pump out 381 horsepower.

The Toyota 4Runner has a spacious interior that can accommodate up to seven passengers, making it a great family car. Additionally, it boasts various safety features, including a rearview camera, lane departure warning, and many more. Overall, the Toyota 4Runner is a car that’s both practical and fun to drive.

Why Gas Mileage is Important

Gas mileage, or how far a car can travel on a gallon of gas, is an essential factor to consider when purchasing a vehicle. Fuel costs can be a significant expense, especially for those who use their vehicles daily. Additionally, a car that has good gas mileage can be better for the environment, as it produces fewer carbon emissions.

Moreover, owning a car with good gas mileage can save you money in the long run. For instance, let’s say you drive a car that gets 20 miles per gallon (MPG) and drive 15,000 miles per year. If gas costs $3 per gallon, you will spend around $2,250 on gas per year. However, if you drive a car that gets 30 MPG or more, you will spend only $1,500 on gas per year, a $750 difference. Calculating gas mileage is essential as it can impact both your wallet and the environment.

The vehicle’s gas mileage can decrease depending on your driving habits, the terrain, and other factors.

Furthermore, the Toyota 4Runner has impressive off-road capabilities, which may affect its gas mileage. Still, the car’s performance off-road is outstanding, making it a favorite among off-road enthusiasts.


The Toyota 4Runner is a popular mid-size SUV that offers both off-road capabilities and practicality. Gas mileage is an essential factor to consider when purchasing a vehicle, and the 4Runner’s gas mileage varies depending on several factors. However, owning a car with good gas mileage can save you money in the long run and is better for the environment. Ultimately, the Toyota 4Runner’s gas mileage is competitive with its peers, and its performance off-road is outstanding.

Factors that Affect Toyota 4Runner Gas Mileage

Engine Type

The Toyota 4Runner has two engine types – the V6 and the V8. The V6 engine has smaller cylinders compared to the V8 engine, which means it requires less fuel to operate. Thus, it has better gas mileage than the V8 engine. If you are looking for a more fuel-efficient 4Runner, then the V6 engine is a better choice. However, if you prioritize power over fuel economy, then the V8 engine is the way to go.

Driving Conditions

The driving conditions that you encounter also have a significant impact on the fuel efficiency of your Toyota 4Runner. For instance, driving on a flat road with no wind and no heavy loads can result in better gas mileage than driving uphill with cargo or against the wind. Additionally, driving at high speeds can increase fuel consumption, resulting in lower gas mileage. To improve your 4Runner’s fuel efficiency, avoid driving it in extreme conditions like hills or high speeds.

Driving Habits

Your driving habits also play a vital role in determining the fuel efficiency of your Toyota 4Runner. Driving aggressively, such as sudden acceleration and hard stops, can significantly lower gas mileage. These driving habits can cause your engine to work harder by consuming more fuel. On the other hand, driving gently, such as accelerating slowly and braking smoothly, can improve gas mileage. Maintaining a consistent speed with gradual acceleration and deceleration reduces the need for your 4Runner to consume more fuel, thereby improving overall gas mileage.

By understanding the factors that affect Toyota 4Runner gas mileage, you can optimize your vehicle’s fuel efficiency. Choosing the right engine type, avoiding driving harshly, and driving with care and consideration for your vehicle’s limitations are all key steps towards a more fuel-efficient Toyota 4Runner.

How to Improve Toyota 4Runner Gas Mileage

Maintaining the Vehicle

Regular vehicle maintenance is crucial when it comes to improving gas mileage for your Toyota 4Runner. Keeping up with regular maintenance routines will ensure that the vehicle runs at its optimal efficiency, resulting in better gas mileage. Some of the most critical maintenance practices include properly inflating the tires, regular oil changes, and cleaning air filters.

Underinflated tires can increase resistance between the tires and the road, causing the engine to work harder. On the other hand, overinflated tires might cause uneven tire wear. So, it’s recommended that you keep your vehicle’s tires inflated according to the manufacturer’s recommended PSI level. A quick monthly tire pressure check only takes a few minutes and will result in significant fuel savings.

Moreover, regularly changing your Toyota 4Runner’s oil is essential for improving gas mileage. Dirty oil can increase engine friction, which makes it harder for the engine to run efficiently. It’s recommended that you follow the manufacturer’s recommended oil change schedule to keep your 4Runner’s engine running smoothly.

Lastly, clean air filters are essential when it comes to improving gas mileage. A dirty air filter can reduce the airflow while increasing the engine’s workload resulting in reduced fuel economy. It’s recommended that you replace the air filter every 12,000 miles.

Reducing Weight

Another way to improve your Toyota 4Runner’s gas mileage is by reducing the weight of the vehicle. Removing any unnecessary cargo or equipment will reduce the weight of the vehicle, which means that the engine will have to work less hard to run the vehicle, and fuel economy will improve as a result.

You can also opt for lighter accessories for your 4Runner, such as aluminum wheels, to further reduce the weight of the vehicle. However, it’s essential to keep in mind that some modifications, such as oversized tires and lift kits, can have the opposite effect, reducing fuel economy instead of improving it.

Changing Driving Habits

Changing driving habits can significantly impact fuel economy. Hard acceleration and sudden stops can increase fuel consumption, so try to avoid these driving habits as much as possible. Gradually accelerating and braking, maintaining a steady speed, and using cruise control on the highway can all help improve fuel economy.

It’s also recommended that you avoid idling when possible, especially when parked for more than 10 seconds. Additionally, try to avoid driving at high speeds, as the faster you drive, the more fuel your vehicle will consume.

Finally, planning your trips can also help improve fuel economy. Combine your errands into one trip, avoid rush hour traffic, and use GPS or a map to plan the shortest route possible, reducing mileage and thus fuel consumption.


Improving the gas mileage of your Toyota 4Runner can help decrease fuel expenses significantly. Regular maintenance, reducing weight, and changing driving habits can all make a difference when it comes to fuel economy. Try implementing some of these techniques to get the most out of your 4Runner’s fuel efficiency.
