The 2020 Ram 1500 2WD with the 3.0L diesel engine gets 26 MPG combined, so it won’t win any hypermiling contests, but that number represents a sweet spot for truck buyers who need real capability without constantly needing to fill up. This truck targets a specific buyer, someone who needs to tow occasionally, appreciates a comfortable ride, and wants a touch of luxury, all without the compromises of a full-on heavy-duty pickup.

City and highway performance

The 2020 Ram 1500 2WD gets 22 MPG in the city and 32 MPG on the highway. The city figure reflects stop-and-go traffic and the truck’s weight, while the highway number showcases the diesel engine’s efficiency paired with the smooth eight-speed automatic transmission. That 32 MPG allows for genuinely long-distance cruising without constant fuel stops, enhancing the Ram 1500’s appeal as a road trip machine.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Ram 1500 2WD 3.0L diesel at $2,150. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s a standardized calculation, allowing buyers to directly compare the Ram 1500’s running costs to other vehicles, regardless of their location. Remember that changes in fuel prices will directly impact this number, as will individual driving habits.

Real-world expectations

EPA figures provide a baseline, but real-world fuel economy for the 2020 Ram 1500 2WD 3.0L diesel will vary depending on several factors. Driving style is a primary influence; aggressive acceleration and hard braking will decrease fuel economy. Hauling heavy loads or towing a trailer will also significantly reduce MPG. Properly maintaining the vehicle, including tire inflation and regular servicing, is critical to achieving optimal fuel efficiency, allowing drivers to come closer to the EPA estimates. Wind resistance will also greatly impact fuel economy, making it difficult to reach 32 MPG on the highway.

How it compares

Compared to similarly sized trucks, the 2020 Ram 1500 2WD with the 3.0L diesel shines when it comes to fuel economy. For example, a comparable gasoline-powered 2020 Ford F-150 2WD with the 2.7L EcoBoost engine achieves around 22 MPG combined. A Chevrolet Silverado 1500 2WD with the 5.3L V8 lands in a similar range. The Ram’s diesel engine offers a noticeable advantage in highway MPG, which really matters for those who frequently travel long distances, and even compared to the hybrid Ford Maverick, it’s clear why many buyers prefer the Ram’s capability, ride, and comfort.

Tips to maximize efficiency

Gentle acceleration and avoiding hard braking are important to maximizing fuel economy in any vehicle but especially so in a truck. The 2020 Ram 1500 2WD responds well to a smooth and deliberate driving style. Avoid quick starts, and anticipate traffic flow to maintain a steady pace.

Proper tire inflation is critical. Check your tires regularly and maintain the pressure specified on the doorjamb sticker. Underinflated tires increase rolling resistance, which puts additional strain on the engine and decreases fuel efficiency. Don’t exceed the maximum inflation pressure listed on the tire’s sidewall; stick with the manufacturer’s recommendation.

Minimize idling. The Ram’s diesel engine consumes fuel even when stationary. If you anticipate being stopped for more than a minute, shut off the engine. Modern diesel engines start quickly and reliably, making this a simple way to conserve fuel, especially in urban environments.

Carefully consider any aftermarket modifications. Lift kits, oversized tires, and roof racks can significantly increase wind resistance and weight, reducing fuel economy, so if lower fuel costs are a priority, avoid modifications that compromise the vehicle’s aerodynamics or add unnecessary weight.

Service the truck according to the manufacturer’s recommendations, as regular oil changes, air filter replacements, and fuel filter maintenance ensure the engine operates efficiently. A well-maintained engine consumes less fuel and produces fewer emissions.
