The 2018 Toyota Tundra 4WD with the 5.7L V8 gets 14 MPG combined. This isn’t a badge of honor, but a reality accepted by those who need what this truck offers: strong capability, renowned Toyota reliability, and the muscle to haul heavy loads or navigate challenging terrain. The Tundra 5.7L isn’t bought by those worried about less gas; it’s the choice of contractors, ranchers, and off-road enthusiasts who prioritize function over frugality.

City and highway performance

The EPA estimates the Tundra 5.7L 4WD at 13 MPG in the city and 17 MPG on the highway. These numbers reflect its large engine, heavy weight, and a traditional six-speed automatic transmission. Stop-and-go city driving will hurt your fuel bill, as the Tundra’s mass requires energy to start moving. Highway driving, while better, is still affected by the truck’s less aerodynamic shape. While some drivers might see slightly better results under ideal conditions, the EPA numbers serve as a reasonable expectation.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Toyota Tundra 4WD 5.7L at $3,150. This figure is calculated based on 15,000 miles of driving per year, using the national average fuel prices. Owning a truck like this comes with a financial commitment beyond the initial purchase price. Fluctuations in fuel prices will directly impact this annual expense, and those who drive more than 15,000 miles annually will face an even higher bill.

Real-world expectations

Owners often report fuel economy figures that match or fall slightly below the EPA estimates. Driving style, terrain, and tire pressure are important factors. Aggressive acceleration, frequent towing, and driving on rough roads will all negatively impact fuel efficiency. A conservative driving style, regular maintenance, and properly inflated tires can help you get closer to the EPA’s projections, but don’t expect miracles.

How it compares

Compared to its competitors, the 2018 Tundra 5.7L 4WD has lower fuel economy. The Ford F-150, particularly with its EcoBoost engines, gets better MPG, often in the 17-20 MPG combined range depending on the configuration and drivetrain. The Ram 1500, with its Hemi V8, frequently manages a slightly better combined MPG. The Chevrolet Silverado 1500 and GMC Sierra 1500, while similar in capability, also often outperform the Tundra in fuel efficiency, especially with their more advanced eight-speed transmissions. This difference highlights a tradeoff: sacrificing fuel economy for Toyota’s proven reliability and resale value.

Tips to maximize efficiency

Due to the Tundra’s large engine, gentle acceleration and anticipating traffic can improve fuel economy. Avoid aggressive starts and try to maintain a steady speed.

Ensure your tires are properly inflated to the recommended pressure, which can be found on the sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, forcing the engine to work harder. Also, check all Toyota fuel economy data to compare to models with different tire sizes.

Reduce unnecessary weight in the truck bed. Hauling around extra tools or equipment adds to the vehicle’s overall weight, requiring more energy. Unload any items you don’t need. This is especially important for off-roaders who often add aftermarket equipment.

Consider the type of fuel you’re using. The Tundra 5.7L is designed to run on regular gasoline, using a higher-octane fuel might yield marginal improvements in performance and efficiency when towing or hauling heavy loads. Experiment to see if it makes a difference for your driving style.

Regular maintenance is key to good fuel economy. Ensure that your Tundra receives scheduled oil changes, air filter replacements, and spark plug maintenance. A well-maintained engine is more efficient.
