22 MPG combined from a 2017 Ram 1500 4×4 with the 3.0L EcoDiesel V6 is a number that needs context. This isn’t a compact crossover promising hybrid-like efficiency, it’s a full-size, four-wheel-drive truck capable of serious work, hauling materials, and navigating difficult terrain. Buyers who accept this level of fuel economy are prioritizing capability, durability, and the utility that only a truck can offer. They’ve likely considered all Ram fuel economy data and determined this specific configuration is best for them.

City and highway performance

The EPA estimates 19 MPG in city driving and 27 MPG on the highway. City MPG will likely be lower if the truck is routinely used for short trips with frequent stops and starts while loaded. The 27 MPG highway number is achievable, but maintaining that number requires a disciplined approach to speed and throttle input, especially given the aerodynamic profile of a full-size pickup.

Factors like towing, payload, and even aftermarket accessories (lift kits, oversized tires) can significantly reduce real-world MPG on both city and highway routes. The eight-speed automatic transmission helps optimize engine efficiency at various speeds, a critical component in achieving these ratings.

Annual fuel cost

The EPA estimates the annual fuel cost for this 2017 Ram 1500 4×4 EcoDiesel is $2,550. This is based on driving 15,000 miles per year and using national average fuel prices. It’s important to understand this is an estimate, and your individual fuel costs will vary based on your driving habits, fuel prices in your area, and the type of driving you do. If the truck sees more city driving, or is frequently used for towing, your actual fuel expenditure will likely exceed the $2,550 projection.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy for the 2017 Ram 1500 4×4 EcoDiesel can change quite a bit. Owners have reported numbers ranging from slightly below the EPA estimates to exceeding them on long highway trips. Factors influencing these variations include driving style, load weight, tire pressure, and weather. Aggressive acceleration, frequent braking, and high speeds will hurt fuel consumption. Consistent maintenance, including regular oil changes and tire rotations, can help maintain optimal efficiency.

Fuel blends can affect mileage, with winter blends often resulting in a slight decrease in MPG.

How it compares

Compared to other full-size trucks, the 2017 Ram 1500 4×4 EcoDiesel does well. For example, a 2017 Ford F-150 4×4 equipped with the 2.7L EcoBoost V6 engine achieves an EPA-estimated 20 MPG combined. A similarly equipped 2017 Chevrolet Silverado 1500 4×4 with the 5.3L V8 posts a combined figure of 18 MPG. These differences matter to buyers who need the capability of a full-size truck but are also conscious of fuel costs. The Ram’s EcoDiesel offers a good balance of power and efficiency, especially when compared to V8-powered alternatives. However, accessing 1500 MPG across all years will highlight the subtle differences by model year.

Tips to maximize efficiency

Use a gentle driving style, gradually accelerating and avoiding hard braking. The EcoDiesel engine delivers ample torque at low RPMs, so there’s no need to aggressively rev the engine. Consistent, moderate throttle input will contribute to better fuel economy. Think ahead and anticipate traffic conditions to minimize unnecessary acceleration and braking.

Keep proper tire inflation. Under-inflated tires increase rolling resistance, leading to decreased fuel efficiency. Check your tire pressure regularly and inflate to the recommended levels indicated on the doorjamb sticker. Even a few PSI difference can affect fuel consumption over time.

Reduce unnecessary weight. Hauling extra cargo adds strain on the engine and reduces fuel economy. Remove any unnecessary items from the bed of the truck and cab to lighten the load. Every pound counts, especially in city driving where you’re constantly accelerating and decelerating.

Avoid prolonged idling. If you’re going to be stopped for more than a minute, turn off the engine. Idling consumes fuel without covering any distance. This is important in urban environments where idling is common. Start/stop technology available on some trims could also prove useful to drivers prioritizing less gas.
