What gas mileage does a 5.7 Tundra get?

In typical configurations, a 5.7-liter Toyota Tundra yields mid-teens in city driving and high-teens to around 20 mpg on the highway. The exact numbers vary by year, cab/bed configuration, and drivetrain, with 4x2 versions generally more fuel-efficient than 4x4 variants.

EPA fuel economy by drivetrain and configuration

EPA estimates vary by year and configuration. Below are representative figures for common 5.7L V8 Tundra setups, reflecting typical two-wheel-drive and four-wheel-drive configurations.

• 4x2 Regular Cab / Access Cab with 5.7L V8: approximately 15 mpg city and 19–20 mpg highway.


• 4x4 CrewMax with 5.7L V8: approximately 14 mpg city and 17–18 mpg highway.

In short, 4x2 configurations tend to deliver higher highway efficiency, while 4x4 versions sacrifice some mpg for off-road capability and payload.

Real-world factors that influence fuel economy

Beyond those EPA numbers, several practical factors can move actual mileage up or down in daily use.

• Driving style and acceleration: aggressive starts and frequent hard braking reduce mpg.


• Payload and towing: hauling heavy loads or towing can significantly lower fuel efficiency.


• Terrain, topography, and weather: hilly roads, hot/cold temperatures, and headwinds affect mileage.


• Maintenance, tires, and air pressure: proper tire inflation, regular maintenance, and correct spark timing help sustain MPG.


• Vehicle age and condition: older vehicles or ones with worn components typically see lower fuel economy.

Real-world mileage often trails EPA estimates, especially when towing or operating in challenging conditions.

Summary

A 5.7L Tundra typically delivers mid-teens in city driving and high-teens to around 20 mpg on highways, with numbers varying by cab/bed configuration and whether the truck is 4x2 or 4x4. Note that the 5.7L engine is no longer offered in the current Tundra lineup; Toyota now sells trucks with a 3.5L V6 hybrid as the modern standard. For buyers of older 5.7L Tundras, use the EPA figures above as a general guide and expect real-world results to vary with load, driving style, and conditions.

What is the gas mileage on a Toyota Tundra 5.7 L V8?

2021 Toyota Tundra MPG
The difference between the 2021 and 2022 was quite stark, as substantial changes were made after the 2021 model year. This version yielded 13 mpg city and 17 mpg highway, thanks in large part to the 5.7L V-8 engine, with the 381 hp / 401 lb-ft of torque configuration.

Is the 5.7 V8 Tundra a good engine?

Yes, the Toyota Tundra 5.7L V8 is generally considered a good and reliable engine, known for its power and longevity, especially with proper maintenance. However, it is not without common issues, most notably a potential problem with the Secondary Air Injection System (SAIS) in earlier models and water pump failure around 100,000 miles.

Pros of the 5.7L V8 engine

• Power and capability: The 5.7L engine offers strong performance, with high horsepower and torque, making it well-suited for towing and hauling. 
• Longevity: Many owners report high mileage and longevity, with some exceeding 300,000 miles and others reaching over 500,000 with proper care. 
• Reliability: It's a durable engine with a reputation for being dependable over the long term. 
• Timing chain: Unlike some older Toyota engines, the 5.7L uses a timing chain, which is designed to last the life of the engine and avoids the need for costly timing belt replacements. 
• Available tow package: Models equipped with the tow package come with transmission and engine oil coolers for enhanced durability when towing. 

Common issues and cons

• Secondary Air Injection (SAIS) failure: The SAIS can fail, especially in earlier models. This is often an expensive repair, but many owners opt for a bypass kit to avoid the issue from reoccurring, according to this Canadian Gearhead article and Reddit users. 
• Water pump failure: The water pump can fail around 100,000 miles due to bearing failure. However, the design intentionally includes a weep hole, so you'll likely see coolant leaks before a total failure occurs. 
• Early model issues: Some early versions of the engine, around 2007, may have had additional issues such as problems with cam gear vvti actuators, timing chain tensioners, and cam tower oil leaks. However, later model years and updated pumps helped address some of these moisture-related problems.

Is a 5.7 V8 good on gas?

5.7L HEMI V8 Engine. Fuel Efficiency (4X2): 15 mpg city/22 mpg highway.

Which Tundra has the best MPG?

The best gas mileage for a Tundra is from the non-hybrid i-FORCE 4x2 configurations, which can achieve up to 18 mpg city / 24 mpg highway for models like the 2024 SR. The i-FORCE MAX hybrid powertrain offers a slight improvement in city driving (19 mpg city) but has a lower highway rating (20-23 mpg highway), resulting in a similar or slightly lower combined MPG for many trims compared to the base non-hybrid models.

Best MPG by configuration (for 2024 models) 

• i-FORCE 4x2 (non-hybrid): The highest ratings are found on trims like the SR, with 18 mpg city / 24 mpg highway (20 mpg combined). 
• i-FORCE MAX 4x2 (hybrid): The hybrid powertrain on the Capstone trim gets 19 mpg city / 22 mpg highway (21 mpg combined). 
• i-FORCE MAX 4x4 (hybrid): Some hybrid 4x4 trims get slightly lower ratings, such as the Platinum or 1794 Edition at 19 mpg city / 22 mpg highway (20 mpg combined). The TRD Pro hybrid is rated at 18 mpg city / 20 mpg highway (19 mpg combined).

Factors affecting fuel economy

• Engine: The non-hybrid twin-turbocharged V6 (i-FORCE) is the most fuel-efficient in many situations. 
• Drivetrain: A two-wheel drive (4x2) configuration will generally have better fuel economy than a four-wheel drive (4x4) model. 
• Driving conditions: Hybrid models see their best results in city driving due to the electric motor, while the hybrid's highway performance can be similar or slightly worse than the non-hybrid due to added weight.
