19 MPG combined. This isn’t a number that will lure hybrid shoppers or Prius loyalists. But for the 2019 Nissan Frontier 2WD with the 4.0L V6, it’s a firmly established reality, and one that its owners have come to accept, even appreciate, as part of the truck’s overall character. This isn’t a fuel-sipping, eco-conscious machine; it’s a workhorse, a reliable tool built for simpler times and tougher tasks. Its gas mileage is a known quantity, a trade-off made for its proven durability and no-nonsense functionality.

City and highway performance

The EPA estimates that the 2019 Frontier 2WD V6 achieves 16 MPG in the city and 23 MPG on the highway. The city figure reflects the engine’s tendency to work a bit harder in stop-and-go traffic, highlighting that this V6 is built for consistent power delivery rather than maximizing efficiency at lower speeds. On the open road, the 23 MPG rating is respectable, though not groundbreaking. The 5-speed automatic transmission, while generally reliable, doesn’t offer the gear ratios or more advanced programming of modern transmissions. This contributes to slightly lower highway fuel economy compared to some of its competitors. Highway driving is the Frontier’s preferred zone. Steady speeds and reasonable loads get the best out of this powertrain.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Nissan Frontier 2WD V6 to be $2,300. This figure is based on driving 15,000 miles per year, using a blend of 55% city and 45% highway driving, and factoring in the national average fuel prices at the time of calculation by the EPA. It’s a significant cost, especially when compared to more fuel-efficient trucks or smaller SUVs. Potential buyers need to honestly assess their driving habits and typical annual mileage to determine if this number fits within their budget. For many Frontier owners, this cost is viewed as the price of entry for a dependable truck that avoids the complex technology and potentially higher maintenance costs of newer, more fuel-efficient vehicles. You can review all Nissan fuel economy data to see if this number compares favorably within their lineup.

Real-world expectations

While the EPA provides a useful benchmark, real-world fuel economy can vary substantially based on driving style, load, and terrain. Aggressive acceleration, frequent towing, or driving in hilly areas will decrease fuel efficiency. Gentle acceleration, consistent highway speeds, and regular maintenance can help owners achieve fuel economy closer to the EPA estimates. Many Frontier owners report that it’s possible to exceed the EPA highway number with careful driving, while city MPG often hovers around the stated 16 MPG figure. Driver behavior has a significant impact on the actual gas mileage experienced with the 2019 Frontier.

How it compares

Compared to its mid-size truck rivals, the 2019 Nissan Frontier’s fuel economy is generally on the lower end. For example, a similar-year Toyota Tacoma with a V6 engine and two-wheel drive often achieves a slightly better combined MPG, around 20-21 MPG. The Chevrolet Colorado and GMC Canyon, with their available four-cylinder or V6 engines, also tend to offer marginally better fuel economy depending on the specific configuration. Even the Ford Ranger, reintroduced in 2019, edges out the Frontier in fuel efficiency, offering around 22-23 MPG combined in its 2WD configuration. However, many Frontier buyers prioritize the truck’s lower purchase price and straightforward mechanicals over marginal improvements in fuel economy offered by competitors. They might also be looking at FRONTIER MPG across all years to help with their decision.

Tips to maximize efficiency

Regular maintenance is critical for optimizing fuel economy in the 2019 Frontier. Ensure that the engine is properly tuned, the tires are correctly inflated (to the pressure listed on the door placard), and the air filter is clean. These simple steps can prevent the engine from working harder than necessary and consuming excess fuel.

Avoid aggressive acceleration and hard braking. Smooth, gradual acceleration allows the engine to operate more efficiently, while gentle braking minimizes wasted energy. Anticipate traffic conditions and maintain a steady speed to reduce fuel consumption.

Minimize unnecessary weight in the truck bed or cabin. Extra weight increases the engine’s workload and reduces fuel economy. Remove any items that are not essential for your daily driving or work needs.

When hauling cargo or towing a trailer, be mindful of the increased fuel consumption. Distribute the load evenly and drive at moderate speeds to reduce strain on the engine. Consider using a bed cover to improve aerodynamics when not hauling large items.

Consider upgrading to low rolling resistance tires when it’s time for a replacement. These tires are designed to reduce friction between the tire and the road surface, which can improve fuel economy by a small but measurable amount. Consult with a tire specialist to find the best option for your driving needs and typical use case.
