17 MPG combined. The 2022 Toyota 4Runner 4WD 4.0L isn’t known for its fuel efficiency, and Toyota acknowledges this. This is a body-on-frame SUV built for serious off-road capability and long-term durability, not hypermiling. The people who buy this vehicle, outdoors enthusiasts, overlanders, and those who prioritize reliability above all else, understand this tradeoff and accept it. They’re buying legendary Toyota dependability and go-anywhere competence, and they’re prepared to pay the price at the pump.

City and highway performance

The EPA estimates suggest 16 MPG in the city and 19 MPG on the highway. These numbers become apparent quickly. Stop-and-go traffic punishes the 4.0L V6, an engine that prefers open roads. Highway driving is slightly less problematic, but the 4Runner’s boxy shape and five-speed automatic transmission limit its efficiency. Expect a considerable drop in mileage when towing or carrying heavy loads, both common occurrences for many 4Runner owners. The older five-speed automatic means the engine often runs at higher RPMs on the highway than newer six, eight, or ten speed transmissions, which hurts fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Toyota 4Runner 4WD 4.0L at $2,600 per year. This is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using the national average fuel price at the time of calculation. It’s a useful guide, but your actual fuel costs will vary depending on your driving habits, location, and the price of gasoline. If you live in an area with high fuel prices or drive significantly more than 15,000 miles annually, expect to spend much more. Review 4RUNNER MPG across all years for comparison over time.

Real-world expectations

While some drivers might occasionally achieve slightly better numbers under ideal conditions, 17 MPG is a realistic average. Aggressive driving, especially in the city, will likely result in even lower figures. Conversely, long highway trips at a steady pace may get you closer to the EPA highway estimate.

The 4Runner’s fuel economy is predictable, consistently mediocre, and largely dependent on your driving style and environment. Owners have noted that larger, heavier tires often fitted for off-roading can further reduce economy.

How it compares

The 4Runner’s fuel economy is worse than many of its competitors. For example, a Jeep Wrangler Unlimited with the 2.0L turbocharged four-cylinder achieves a combined EPA rating of 22 MPG. Even a V6-powered Jeep Grand Cherokee 4×4 often surpasses 21 MPG combined. A Ford Bronco with the 2.3L EcoBoost engine reaches around 20 MPG combined. These differences are significant. For the 4Runner buyer, fuel economy is not the primary factor. Instead, the focus is on the 4Runner’s proven reliability, strong construction, and impressive resale value, factors that often outweigh fuel costs. Those seeking less gas consumption should review all Toyota fuel economy data and compare against other similar models.

Tips to maximize efficiency

The 4Runner will never be a fuel sipper, but you can save gas.

Maintain a steady speed on the highway, avoiding sudden acceleration and braking. The 4.0L V6 responds best to smooth, deliberate inputs.

Ensure your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance and reduce fuel economy. Check your tire pressure regularly, especially with temperature changes.

Reduce unnecessary weight. Remove any items you don’t need from the vehicle, especially heavy equipment or gear that adds to the overall load.

Minimize idling time. If you’re stopped for more than a minute, turn off the engine. Idling wastes fuel, especially during cold starts.

Consider using cruise control on long highway drives. Cruise control can help maintain a consistent speed, reducing the amount of throttle input required and improving fuel efficiency.
