The 2023 Ram 1500 4WD with the 3.0L diesel gets 24 MPG combined, an impressive figure considering its purpose. It’s a full-size pickup designed for hauling, towing, and tackling tough terrain, not an aerodynamic crossover. Buyers who accept the Ram’s fuel economy appreciate its blend of utility, comfort, and capability more than prioritizing ultimate efficiency.

City and highway performance

EPA estimates suggest 21 MPG in the city and 29 MPG on the highway. That highway number stands out. The 3.0L inline-six turbodiesel, known as the “EcoDiesel,” shines on long highway runs. Its ample torque and relaxed cruising demeanour allow it to achieve these numbers. The city rating reflects stop-and-go traffic taking its toll as it does on any large vehicle. However, even 21 MPG is respectable for a 4WD pickup that often weighs close to 6,000 pounds depending on configuration.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Ram 1500 4WD 3.0L diesel at $2,300 per year. This is based on driving 15,000 miles annually, using a blend of city and highway driving, and calculated using national average fuel prices. Your actual fuel costs will vary depending on your driving habits, where you live, and local fuel prices. For individuals who frequently tow heavy loads or spend a significant amount of time in slow-moving traffic, the annual fuel cost could easily exceed this estimate. Conversely, drivers primarily using their Ram for long highway commutes may find they spend less than $2,300 annually at the pump.

Real-world expectations

While the EPA estimates provide a solid baseline, real-world fuel economy can vary considerably. Factors such as driving style, load weight, tire pressure, and even the weather can all play a role. Ram 1500 owners who frequently use their truck for towing or off-roading will likely see lower MPG figures than those who primarily use it for commuting. Aggressive driving habits, such as hard acceleration and braking, will also negatively impact fuel economy.

How it compares

The Ram 1500’s fuel economy holds up relatively well against its competitors, especially considering the capability it offers. The Ford F-150 with the 3.5L EcoBoost V6 and 4WD, for example, is rated at 20 MPG combined. The Chevrolet Silverado 1500 with the 3.0L Duramax diesel and 4WD gets slightly better figures, clocking in at 26 MPG combined. However, Ram loyalists often prioritize the Ram’s coil spring rear suspension and refined interior over chasing the absolute best MPG numbers. The Toyota Tundra, with its non-hybrid powertrains typically lags behind both the Ram and the GM trucks in fuel economy. See all Ram fuel economy data to compare it to other models in the lineup.

Tips to maximize efficiency

One of the easiest ways to improve fuel economy in the Ram 1500 is to maintain proper tire pressure. Check your tires regularly and inflate them to the recommended pressure listed on the driver’s side doorjamb. This reduces rolling resistance and can have a noticeable effect on MPG, particularly on long highway trips.

Avoid aggressive driving habits such as rapid acceleration and hard braking. The diesel engine provides plenty of torque at low RPMs, so accelerate smoothly and gradually. Anticipate traffic flow to minimize unnecessary braking and maintain a steady speed.

Reduce excess weight in the bed of the truck. Carrying unnecessary cargo adds to the overall weight of the vehicle, which decreases fuel economy. Only carry what you need for the current trip, and remove any unused items from the bed and cab.

Minimize idling. Diesel engines are most efficient when they are moving. If you’re going to be stopped for more than a minute or two, turn off the engine. Restarting the engine consumes less fuel than idling for an extended period.

Consider using the Ram’s available drive modes to optimize fuel efficiency. If equipped, the “Eco” mode can adjust engine and transmission settings to prioritize fuel economy over performance. Learn the available modes and use them appropriately for the driving conditions.
