19 MPG combined is an acceptable figure for the 2015 Ram 1500 4WD with the 3.6L V6. This isn’t a compact crossover; it’s a full-size truck with four-wheel drive. Buyers aren’t expecting Prius-like efficiency. They are prioritizing towing capacity, payload, and all-weather traction, willing to trade some MPGs for the Ram’s strong utility.

City and highway performance

The EPA estimates suggest 16 MPG in the city and 23 MPG on the highway. These numbers reflect the characteristics of a large truck. In city driving, frequent stop-and-go traffic and idling affect fuel economy, especially with the drag of the four-wheel drive system (even when not engaged). The 8-speed automatic transmission helps reduce the impact by keeping the engine in its optimal power band.

On the highway, the Ram 1500’s aerodynamics come into play. While 23 MPG is achievable, maintaining it consistently requires careful driving and moderate speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 Ram 1500 4WD 3.6L V6 at $2,300 per year. This calculation is based on driving 15,000 miles annually, with a mix of city and highway driving that aligns with the EPA’s combined MPG figure. The estimate also uses the national average fuel price at the time of calculation.

This is just an estimate. Your actual fuel expenses will vary depending on your driving habits, the type of driving you do, and the fluctuating price of gasoline.

Real-world expectations

While the EPA provides a useful benchmark, real-world fuel economy often deviates. Some owners of the 2015 Ram 1500 4WD 3.6L report figures slightly below the EPA estimates, especially those who frequently tow or haul heavy loads. Aggressive driving, significant idling, and aftermarket modifications (such as larger tires or lift kits) can also negatively affect MPG.

However, drivers who prioritize fuel efficiency and spend most of their time on the highway may see numbers closer to, or even slightly above, the EPA’s 23 MPG highway estimate.

How it compares

The 2015 Ram 1500 4WD 3.6L’s fuel economy stacks up well against its competitors. A similarly equipped 2015 Ford F-150 4WD with the 3.5L V6 EcoBoost is EPA-rated at 17 MPG combined, giving the Ram a slight edge. The Chevrolet Silverado 1500 4WD with the 4.3L V6 is rated at 19 MPG combined, matching the Ram. The Toyota Tundra, known for its reliability but not its fuel efficiency, lags behind with lower MPG figures.

These comparisons are vital because they highlight that the Ram offers a competitive balance of capability and efficiency within its class. See all Ram fuel economy data here.

Tips to maximize efficiency

Driving style has a big impact on fuel economy. Avoid aggressive acceleration and hard braking. Anticipate traffic flow and maintain a steady speed. The Ram 1500 is hefty and requires more energy to accelerate or slow down.

Proper tire inflation is critical. Check your tires regularly and inflate them to the manufacturer’s recommended pressure, which can be found on the sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel economy.

Minimize idling. If you’re stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, and restarting consumes less fuel than idling. This is especially relevant for truck owners who often spend time on job sites.

Reduce unnecessary weight. Remove any items from the bed of the truck that aren’t needed, as extra weight directly impacts fuel consumption. The less the truck weighs, the less energy it takes to accelerate and maintain speed. You may also adjust your driving behavior based on 1500 MPG across all years
