17 MPG combined won’t win any fuel economy awards, but that’s what you get with a 2019 Nissan Frontier 4WD with the 4.0L V6. This truck is about proven reliability, a no-frills attitude, and tackling jobs where a full-size pickup feels like overkill. Frontier buyers prioritize capability and value over cutting-edge efficiency, accepting the fuel consumption as a trade-off for a reliable and dependable workhorse.

City and highway performance

The EPA estimates for the 2019 Nissan Frontier 4WD are 15 MPG in the city and 21 MPG on the highway. These figures reflect the demands on the 4.0L V6 and 5-speed automatic transmission in different driving conditions. Stop-and-go city driving, with frequent acceleration and braking, taxes the engine and results in lower fuel economy. Highway driving, with its more consistent speeds, allows the engine to operate more efficiently. However, the Frontier’s boxy shape and lack of aerodynamic features create more wind resistance at higher speeds, preventing truly impressive highway MPG.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Nissan Frontier 4WD at $2,600. This is based on driving 15,000 miles per year with a 55/45 split between city and highway driving, assuming a national average fuel price. This is a useful benchmark for comparing it to other vehicles. Your actual fuel costs will change based on your driving, the type of driving you do, and local fuel prices. Fluctuating gas prices can significantly impact this annual cost. To explore all Nissan fuel economy data, including other models, you can explore the resources on FuelEconomyHub.com.

Real-world expectations

EPA estimates provide a baseline, but actual fuel economy for the 2019 Nissan Frontier often changes based on driving styles and conditions. Owners who frequently tow, haul heavy loads, or go off-roading will likely see MPG figures below the EPA estimates. However, drivers who primarily commute on relatively flat terrain and maintain a gentle driving style may achieve slightly better fuel economy.

Tire pressure and overall vehicle maintenance also play a critical role in optimizing fuel efficiency. If you want to examine FRONTIER MPG across all years a little digging can help.

How it compares

Compared to its competitors, the 2019 Nissan Frontier 4WD’s fuel economy is generally lower. A 2019 Toyota Tacoma 4WD with the 3.5L V6, for instance, gets a slightly better 18 MPG combined. Even the Chevy Colorado 4WD with the 3.6L V6 manages around 19 MPG combined. These small differences matter to some buyers, pushing them towards competitors that offer even a modest improvement in fuel efficiency. However, many Frontier buyers willingly sacrifice a few MPG for its lower price and reputation for reliability. They see the Frontier as a tool, prioritizing function and value over the latest technology and fuel-saving innovations.

Tips to maximize efficiency

The 4.0L V6 in the Frontier responds well to smooth acceleration, therefore avoid aggressive starts and hard braking, as these actions dramatically decrease fuel economy. Anticipate traffic flow and maintain a steady speed whenever possible.

Make sure your tires are inflated to the manufacturer-recommended pressure. Underinflated tires increase rolling resistance, making the engine work harder and consume more fuel. Check your tire pressure regularly, especially when the temperature changes.

Reduce unnecessary weight in the bed of the truck, since hauling around heavy items puts extra strain on the engine and reduces fuel economy. Also, remove any aftermarket accessories that create excessive wind resistance.

The 5-speed automatic transmission is a simple design, but the 4WD system impacts efficiency. Only use 4WD when necessary on slippery or uneven terrain, because driving in 4WD on dry pavement increases drivetrain friction and significantly lowers MPG.

Regular maintenance, including oil changes with the correct viscosity and tune-ups, is important for maintaining engine performance and fuel economy. A well-maintained engine runs more efficiently, maximizing the power output from each gallon of fuel.
