15 MPG combined. That’s the headline for the 2020 Toyota Tundra 2WD with the 5.7L V8. For some, that’s a dealbreaker, for others, not so much. The Tundra prioritizes dependable truck capability over fuel efficiency. This truck is for buyers who value unwavering reliability, ample towing capacity, and the proven longevity of a naturally aspirated V8. These buyers are often contractors, ranchers, or those who simply prefer the Tundra’s unshakeable reputation for durability, accepting the fuel cost. They need a workhorse, not a Prius.

City and highway performance

The EPA estimates for the 2020 Tundra 2WD 5.7L V8 are 13 MPG in the city and 18 MPG on the highway, which places it in the “thirsty” category. These numbers reflect the engine’s characteristics and the truck’s weight and aerodynamic profile.

The Tundra’s urban fuel consumption suffers from frequent stop-and-go driving, which the large displacement V8 finds particularly inefficient. Out on the open road, the 18 MPG rating is achievable at steady highway speeds, but any attempt at quick acceleration or towing will significantly impact fuel economy. Its automatic transmission is responsive and keeps the engine in its optimal efficiency range.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Toyota Tundra 2WD 5.7L V8 at $2,900 per year. This figure is calculated based on driving 15,000 miles per year, with an assumed fuel price reflecting the national average.

This figure is a critical consideration because it represents a substantial ongoing expense that needs to be factored into the total cost of ownership. While some buyers may be able to offset this cost through business deductions or reduced maintenance expenses (thanks to Toyota’s renowned reliability), it’s a reality that cannot be ignored. This annual cost far exceeds that of many smaller SUVs and sedans, even those with similar horsepower ratings. Buyers will want to research all Toyota fuel economy data before choosing their vehicle.

Real-world expectations

While the EPA estimates offer a benchmark, real-world fuel economy can vary significantly depending on driving habits, load, and conditions. Aggressive driving, frequent towing, and heavy payloads will all decrease fuel economy, potentially dipping below the EPA estimates. Conversely, careful driving, consistent highway cruising, and diligent maintenance can help achieve figures closer to the EPA ratings. Many owners average around 14 MPG in mixed driving conditions. Those predominantly using the Tundra for highway commutes may see slightly better numbers, while those frequently towing or hauling cargo will likely experience lower MPG.

How it compares

The 2020 Toyota Tundra 2WD 5.7L V8 lags behind its competitors in fuel efficiency. The Ford F-150, particularly with its EcoBoost engines, consistently achieves better MPG. For instance, the 2020 F-150 2WD with the 2.7L EcoBoost V6 posts EPA ratings of 20 MPG combined, a significant advantage. The Chevrolet Silverado 1500 and GMC Sierra 1500, especially with their Duramax diesel engines or newer turbocharged options, also offer superior fuel economy. The Ram 1500, with its available eTorque mild-hybrid system, provides a noticeable improvement in fuel efficiency compared to the Tundra.

Buyers choosing the Tundra over these alternatives are typically prioritizing its reputation for solid reliability and long-term durability over outright fuel savings. Exploring TUNDRA MPG across all years can demonstrate the consistency of this powertrain.

Tips to maximize efficiency

While the 2020 Toyota Tundra 2WD 5.7L V8 is not fuel-efficient, there are steps owners can take to get better gas mileage. Gentle acceleration and anticipating traffic flow are crucial. Avoid abrupt starts and stops, as these actions consume significant amounts of fuel. Maintain a steady speed on the highway and use cruise control when possible.

Proper tire inflation is important. Ensure your tires are inflated to the recommended pressure, as under-inflated tires increase rolling resistance and decrease MPG. Regularly check tire pressure, especially when temperatures fluctuate, and adjust accordingly.

Reducing unnecessary weight can also help. Remove any tools or equipment from the bed of the truck when not needed, as extra weight increases fuel consumption. Consider a lightweight tonneau cover to improve aerodynamics and reduce drag, especially on highway drives.

Regular maintenance is essential. Ensure the engine is properly tuned, and the air filter is clean. A clogged air filter restricts airflow, forcing the engine to work harder and consume more fuel. Follow the manufacturer’s recommended maintenance schedule to keep the engine running efficiently.
