The Toyota RAV4 is known for getting decent fuel economy, so it can come as a shock when it starts using more fuel than expected. If you keep track of MPG, you might wonder why you are suddenly dealing with bad gas mileage on your RAV4.
While it’s possible there’s something wrong, the drop in fuel economy could also be due to driving habits. That’s why I cover all of the reasons you may experience bad gas mileage on your Toyota RAV4. I’ll also help you find ways to improve the distance you drive per tank.

Once you know what to expect from the RAV4, it’s much easier to tell when there’s a problem.
Factors That Influence Real-World Gas Mileage

The fuel economy ratings for today’s cars are determined by the U.S. Department of Energy. Unfortunately, these ratings may not necessarily reflect real-world driving.
There are many different real-world scenarios that could affect gas mileage, therefore your actual MPG could be significantly higher or lower than the government ratings.
As an example, my RAV4 features a city rating of 27 mpg. However, it tends to get an average of 23 mpg, which is slightly lower. This is because I frequently take short trips with lots of traffic lights and steep hills.
You should also know that the opposite is true of the RAV4 Hybrid. It actually performs quite well in stop-and-go situations. Consider checking out our post about real-world RAV4 Hybrid gas mileage.
Here are several other factors that affect your real-world mpg rating:
- Aggressive acceleration and braking
- Frequent stop-and-go driving
- Hilly terrain
- Air conditioner usage
- Excessive idling
- Driving at high speeds and aerodynamic drag
- Cold weather
- Cargo racks on the roof
- Towing
If you recognize some of these factors in your daily driving routine, you can expect a drop in fuel economy.
Vehicle Problems That Could Impact Gas Mileage
In some cases, a mechanical issue can lead to poor fuel economy. If the drop is sudden and your driving habits have not changed, it may be a mechanical issue, such as:
- Bad fuel pump
- Failing fuel injectors
- Low tire pressure
- Corroded spark plugs
- Malfunctioning oxygen sensors
- Contaminated engine air filter
- Worn-out piston rings
- Old motor oil and filter
- Dirty mass airflow sensor
- Poor wheel alignment
Many of these problems can be prevented by following your recommended RAV4 maintenance schedule. However, there’s still a chance of mechanical failure even if you are meticulous with your RAV4 care.
The only way to know for sure if a mechanical issue is causing the problem is to have the RAV4 inspected. If you aren’t mechanically inclined, take it to a trusted technician.
