17 MPG combined. That isn’t going to set any fuel-sipping records, but for the 2019 Nissan Frontier 4WD FFV with the 4.0L V6, it’s what you can expect. This is a mid-size truck that prioritizes capability and simplicity over high efficiency. The buyer considering this Frontier isn’t primarily concerned with squeezing every last mile from a gallon; they need a dependable workhorse that can handle tough jobs and occasional off-road adventures without a huge initial cost.

City and highway performance

The EPA estimates the 2019 Frontier 4WD FFV at 15 MPG in the city and 21 MPG on the highway. The city figure reflects the somewhat dated 5-speed automatic transmission and the demands placed on the 4.0L V6 in stop-and-go traffic. The highway number is more palatable, but the Frontier’s boxy shape and lack of advanced aerodynamic features prevent it from achieving significantly better fuel economy at higher speeds. This is a vehicle where maintaining a steady pace is more critical than aggressive acceleration.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2019 Nissan Frontier 4WD FFV is $2,600. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that the actual cost will vary depending on your driving habits, local fuel prices, and the specific grade of fuel used. Some owners might find this a reasonable cost for the truck’s capabilities, while others will find it a significant expense.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy can be different. Owners report that consistently achieving the EPA’s 17 MPG combined often requires effort. Aggressive driving, frequent use of four-wheel drive, and carrying heavy loads will all negatively impact fuel consumption. Conversely, drivers who adopt a more conservative driving style and primarily use the truck for light-duty tasks may find they can match or even slightly exceed the EPA estimates.

It’s important to understand that this Frontier, while dependable, is not particularly forgiving when it comes to driving habits and fuel efficiency.

How it compares

Compared to other mid-size trucks from the same year, the 2019 Frontier’s fuel economy is lower than some rivals. For example, the 2019 Toyota Tacoma 4×4 with its 3.5L V6 is rated at 18 MPG combined. The Chevrolet Colorado and GMC Canyon with the 3.6L V6 and 4WD fared a bit better, at 19 MPG combined. The Ford Ranger, which returned to the market in 2019 with a 2.3L EcoBoost engine, boasts 22 MPG combined with 4×4, and a modern powertrain gives it a significant edge in fuel efficiency. The Frontier customer arguably accepts the MPG difference in exchange for a lower initial purchase price and a simpler, more proven powertrain.

Tips to maximize efficiency

Minimize idling. The 4.0L V6 consumes a noticeable amount of fuel when idling, especially when cold. Avoid letting the engine run unnecessarily, such as when waiting for someone or making short stops.

Drive smoothly and avoid aggressive acceleration. The truck’s 5-speed automatic transmission is geared for work, not for quick acceleration. Gentle acceleration and maintaining a steady speed will significantly improve fuel economy.

Check tire pressure regularly. Underinflated tires increase rolling resistance, which in turn reduces fuel efficiency. Ensure your tires are inflated to the recommended pressure listed on the doorjamb sticker.

Reduce weight and aerodynamic drag. Remove any unnecessary items from the truck bed and consider a low-profile bed cover to improve aerodynamics. Avoid carrying heavy loads unless absolutely necessary.

Service the vehicle on time. Regular maintenance, including oil changes, air filter replacements, and spark plug inspections, ensures the engine runs efficiently. Neglecting maintenance can lead to reduced fuel economy and other performance issues.
