19 MPG combined isn’t going to win any awards, but the 2019 Nissan Frontier 2WD 2.5L exists for a different reason than most modern pickups. It caters to buyers who prioritize simplicity, low cost, and proven reliability over cutting-edge technology and fuel efficiency. This is a work truck, a no-frills hauler, and the fuel economy is simply part of the deal.

City and highway performance

The EPA estimates 17 MPG in the city and 22 MPG on the highway for this configuration of the 2019 Frontier. The difference between city and highway figures reflects the engine’s tuning and the five-speed automatic transmission’s gearing. In city driving, stop-and-go traffic and frequent acceleration place a greater energy demand on the 2.5L four-cylinder.

On the open road, assuming a steady cruising speed, the engine operates more efficiently. However, given that five-speed transmission, don’t expect miracles at 75 MPH. The engine will be turning a fair number of RPMs, impacting fuel economy. These numbers are adequate, not stellar, but entirely predictable for a body-on-frame truck designed for utility rather than economy.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,300 for the 2019 Nissan Frontier 2WD 2.5L. This figure is based on driving 15,000 miles per year and using national average fuel prices. Remember, this is only an estimate and your actual fuel costs may vary significantly based on your driving habits, the type of driving you do, and local fuel prices. Aggressive driving, extended idling, and carrying heavy loads will all increase your fuel consumption, pushing that $2,300 figure higher.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy often differs. Owners of the 2019 Frontier 2WD 2.5L frequently report numbers close to the EPA estimates, but variations are unavoidable. Drivers who primarily use their trucks for short commutes in congested urban areas may see MPG figures closer to the 17 MPG city rating, or even slightly lower. Conversely, drivers who spend most of their time on the highway, maintaining consistent speeds, might see numbers closer to or even slightly exceeding the 22 MPG highway rating. The key takeaway: drive it like a truck, and it will drink fuel like a truck. Drive it with some restraint, and the numbers reported by the EPA are fairly accurate.

How it compares

Compared to other mid-size trucks of its era, the 2019 Frontier 2WD 2.5L doesn’t particularly stand out in terms of fuel economy. The Chevrolet Colorado with its base 2.5L four-cylinder and two-wheel drive offered a slightly better 22 MPG combined for the 2019 model year. The Toyota Tacoma, while generally regarded as the Frontier’s main competitor, achieved roughly similar figures with its equivalent four-cylinder engine, landing around 21 MPG combined. However, the Frontier’s lower purchase price is attractive despite these small fuel economy differences. If saving money upfront is the priority, accepting slightly lower MPG becomes a more palatable tradeoff. Buyers looking at all the possibilities can view all Nissan fuel economy data to compare. And while the V6 variants of the Frontier offer more power, they see a dip in efficiency, solidifying the 2.5L as the economy choice within the FRONTIER MPG across all years.

Tips to maximize efficiency

Gentle acceleration is key. The 2.5L engine, while reliable, isn’t exactly a powerhouse. Stomping on the accelerator to get up to speed will only waste fuel. Instead, accelerate smoothly and gradually to minimize fuel consumption during those initial bursts of energy use. Keeping a light foot can noticeably improve your MPG.

Optimize tire pressure. Ensuring your tires are properly inflated reduces rolling resistance, which directly improves fuel economy. Check your tire pressure regularly and inflate them to the recommended level, which can be found on the sticker inside the driver’s side doorjamb. A few extra PSI can make a noticeable difference.

Reduce unnecessary weight. The more weight your truck carries, the harder the engine has to work, and the more fuel it consumes. Remove any unnecessary items from the bed or cab of your truck. Getting rid of extra weight improves fuel efficiency.

Avoid prolonged idling. Idling burns fuel without covering any distance. If you anticipate stopping for more than a minute or two, turn off the engine. Modern engines are designed to be restarted without significant wear and tear, and the fuel savings from avoiding prolonged idling can add up over time.

Plan your trips strategically. Combining multiple errands into a single trip minimizes cold starts, which are less fuel-efficient. Route planning can also help you avoid congested areas and stop-and-go traffic, further contributing to improved fuel economy. A little forethought can go a long way.
