18 MPG combined. Those three numbers likely aren’t a deal-breaker for anyone seriously considering a 2018 Toyota Tacoma 4WD Double Cab Off-Road with the 3.5L V6 and six-speed manual. This isn’t a Prius; it’s a truck built for trails, hauling, and enduring the kind of abuse that would leave lesser vehicles stranded. Fuel economy is a consideration, sure, but it’s often secondary to capability and outright attitude.
City and highway performance
The EPA estimates the 2018 Tacoma Off-Road at 17 MPG in the city and 20 MPG on the highway. The city figure reflects the stop-and-go reality of urban driving, where the Tacoma’s weight and off-road-tuned drivetrain take their toll. The highway MPG is a bit more palatable, though still far from stellar. You’ll notice the difference on long road trips, especially when compared to more fuel-efficient mid-size trucks or SUVs.
Annual fuel cost
According to the EPA, the estimated annual fuel cost for this particular Tacoma configuration is $2,450. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that this is just an estimate, your actual fuel costs will vary depending on your driving habits, the type of gas you use, and where you live (fuel prices can fluctuate considerably from region to region).
Real-world expectations
The EPA estimates are a good starting point, but real-world MPG often differs. Owners of this Tacoma, especially those who frequently use four-wheel drive or carry heavy loads, often report fuel economy figures slightly below the official EPA ratings. Aggressive driving, aftermarket modifications (such as larger tires or lift kits), and driving at higher altitudes can all negatively impact fuel efficiency. Conversely, careful drivers who stick to paved roads and avoid unnecessary idling can sometimes match or even exceed the EPA’s highway figure.
How it compares
The 2018 Tacoma’s fuel economy isn’t best-in-class. For example, the 2018 Chevrolet Colorado with its available 3.6L V6 can achieve up to 25 MPG on the highway in certain configurations (rear-wheel drive), significantly better than the Tacoma’s 20 MPG. The Honda Ridgeline, with its focus on on-road comfort and fuel efficiency, typically achieves combined MPG figures in the low 20s. However, the Toyota Tacoma is a popular vehicle and you can view TACOMA MPG across all years. The Nissan Frontier, a long-standing competitor to the Tacoma, offers similar fuel economy with its V6 engine, hovering around the same 17-19 MPG combined range.
The comparison matters because someone considering a Colorado or Ridgeline might prioritize fuel economy over the Tacoma’s reliable off-road reputation and strong resale value. The Tacoma buyer is often willing to sacrifice a few MPGs for the peace of mind that comes with owning a durable, capable truck that’s proven itself on challenging terrain.

Tips to maximize efficiency
Minimize idling. The Tacoma’s V6 engine consumes a surprising amount of fuel when idling, especially on cold starts. Turn off the engine if you anticipate being stopped for more than a minute or two.
Maintain proper tire pressure. 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. Also, keep in mind that if you have aftermarket off-road tires, they may require different pressure than stock tires.
Drive smoothly and avoid aggressive acceleration. The Tacoma’s manual transmission allows for precise control over gear selection, but it also places the onus on the driver to optimize fuel efficiency. Avoid unnecessary revving, shift smoothly, and anticipate traffic to minimize hard braking and acceleration.
Use cruise control on the highway. Cruise control helps maintain a constant speed, which reduces fluctuations in fuel consumption. This is especially effective on long, flat stretches of highway where you can maintain a consistent speed.
Lighten the load. The more weight you carry in the Tacoma, the harder the engine has to work, which reduces fuel efficiency. Remove any unnecessary items from the bed or cab, and avoid carrying heavy loads unless absolutely necessary.
