15 MPG combined isn’t going to win any awards, but for the 2015 Toyota Tundra 2WD with the 5.7L V8, it’s simply part of the deal. This truck isn’t about saving fuel; it’s about getting work done, hauling serious loads, and offering the legendary Toyota reliability that Tundra owners trust. No one buys this truck expecting Prius-like economy. They buy it because they need a capable workhorse, and they’re willing to pay at the pump for that capability.

City and highway performance

The EPA estimates the 2015 Tundra 2WD 5.7L V8 at 13 MPG in the city and 18 MPG on the highway. These figures reflect the realities of driving a large displacement, naturally aspirated engine in different conditions. City driving, with its stop-and-go traffic and frequent acceleration, puts a greater strain on fuel consumption. Highway driving, with its more consistent speeds, allows the engine to operate more efficiently but is still affected by the Tundra’s considerable weight and less-than-aerodynamic profile. The six-speed automatic transmission does what it can to optimize fuel use, but ultimately, this engine is built for power and durability, not efficiency.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 Toyota Tundra 2WD 5.7L V8 at $2,900. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s a significant expense, and it’s critical for potential buyers to factor this into their long-term ownership costs. While fuel prices fluctuate, owning a truck like this will always mean a larger fuel bill than a smaller car or even a more modern truck with a smaller engine.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy can vary widely depending on driving habits, road conditions, and vehicle maintenance. Aggressive driving, carrying heavy loads, or towing will all negatively impact fuel economy. Properly maintaining the vehicle, including regular oil changes and tire inflation, can help maintain optimal efficiency. Owners who spend more time on open highways might see figures closer to the 18 MPG highway rating, while those primarily driving in stop-and-go city traffic could see numbers even lower than 13 MPG. Be sure to keep track of your own fuel consumption to understand your Tundra’s specific performance.

How it compares

Compared to its contemporaries, the 2015 Tundra 2WD 5.7L V8’s fuel economy is on par with other full-size trucks of its era. The 2015 Chevrolet Silverado 1500 with the 5.3L V8, for example, is rated at 16 MPG combined, while the Ford F-150 with the 5.0L V8 achieves a similar 17 MPG combined. Buyers often accept these lower MPG figures in exchange for the capabilities and features these trucks offer. Of course, the Ram 1500 EcoDiesel offered significantly better fuel economy, at 23 MPG combined, but diesel ownership comes with its own set of considerations. For those prioritizing fuel efficiency, exploring all Toyota fuel economy data might reveal other models that better suit their needs. And for a broader view, examining the TUNDRA MPG across all years puts this specific model year into perspective.

Tips to maximize efficiency

Gentle acceleration is key to saving fuel in the Tundra. The 5.7L V8 has plenty of power, so there’s no need to floor it from every stop. Smooth, gradual acceleration will minimize fuel consumption and extend the life of your tires.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the doorjamb sticker. This seemingly small step can make a noticeable difference over time.

Avoid unnecessary idling. If you’re going to be stopped for more than a minute or two, turn off the engine. Idling consumes fuel without moving the vehicle, and it’s especially wasteful in a large-displacement engine like the Tundra’s 5.7L V8.

Consider your driving routes. Planning your trips to avoid stop-and-go traffic can significantly improve fuel economy. Opt for routes with more consistent speeds whenever possible. Early morning or late evening driving can sometimes offer less congested roads.
