15 MPG combined isn’t going to win any awards, but that’s the fuel economy of the 2018 Toyota Tundra 4WD FFV 5.7L. It’s a workhorse built for hauling lumber, towing boats, and getting the job done, regardless of terrain, not a grocery-getter. The fuel economy is the price to pay for that kind of capability. Its buyers understand this trade-off.

City and highway performance

The Tundra’s EPA ratings break down to 13 MPG in the city and 17 MPG on the highway. City driving is where the Tundra’s weight and large displacement V8 really burn gas. Stop-and-go traffic hurts efficiency, and the Tundra needs considerable energy to get moving because of its weight. Highway driving offers a slight break. At consistent speeds, the engine isn’t working as hard, but aerodynamic drag keeps economy relatively low.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,900 for the 2018 Toyota Tundra 4WD FFV 5.7L. This figure is based on driving 15,000 miles per year, using a blend of 55% city and 45% highway driving, and assuming national average fuel prices. It’s a benchmark; your actual costs will vary depending on your driving habits and where you live, but it highlights that owners need to budget for fuel if they plan on driving 15,000 miles per year.

Real-world expectations

While the EPA ratings provide a baseline, real-world MPG for the Tundra often falls within a certain range, depending on driving conditions. Towing significantly reduces fuel economy, often dropping it into the single digits. Aggressive acceleration and high speeds also hurt fuel economy. On the other hand, careful driving with minimal heavy acceleration and strategic use of cruise control on the highway can help achieve figures closer to the EPA estimates. However, exceeding the EPA estimates will be challenging, even for the most careful drivers. Check all all Toyota fuel economy data.

How it compares

The Tundra’s fuel economy puts it at the lower end of the full-size truck segment. For example, a 2018 Ford F-150 with the 2.7L EcoBoost V6 achieves around 20 MPG combined. Even a V8-powered F-150 option could achieve slightly better numbers. A Chevrolet Silverado 1500 with the 5.3L V8 is typically rated around 17 MPG combined. Ram 1500 models with the Hemi V8 also often show slightly better fuel economy. These differences matter to some buyers, but Tundra buyers often prioritize reliability and resale value over small gains in fuel efficiency. See TUNDRA MPG across all years.

Tips to maximize efficiency

Maintain proper tire inflation. The recommended pressure for the Tundra is usually found on a sticker inside the driver’s side door. Underinflated tires increase rolling resistance, which forces the engine to work harder and consume more fuel. Checking your tire pressures regularly ensures better fuel efficiency.

Avoid excessive idling. The 5.7L V8 consumes a surprising amount of fuel when idling, even for short periods. If you anticipate being stopped for more than a minute, it’s generally more efficient to turn off the engine and restart it. This practice can make a difference, especially in city driving.

Drive conservatively. Avoid aggressive acceleration and hard braking. The Tundra is a heavy truck, and sudden changes in speed require a significant amount of energy. Smooth, consistent driving not only improves fuel economy but also reduces wear and tear on the drivetrain.

Reduce unnecessary weight. The more weight you carry in the Tundra, the harder the engine has to work. Remove any unnecessary items from the bed and cab. Every extra pound reduces fuel efficiency, especially when accelerating or climbing hills.

Service the truck according to the factory maintenance schedule. Regular oil changes, air filter replacements, and spark plug maintenance ensure the engine is running efficiently. A well-maintained engine consumes less fuel and emits fewer pollutants.
