23 MPG combined won’t win any efficiency awards, but it’s a respectable number for the 2018 Ram 1500 2WD with the 3.0L EcoDiesel V6, a truck designed to blend capability with relative frugality. This configuration appeals to someone who needs the utility of a half-ton pickup for towing and hauling, but isn’t willing to sacrifice fuel economy for brute force. Think of the rancher hauling hay bales, the contractor with a lighter equipment trailer, or the weekend warrior towing a small camper. They accept this MPG because it represents a sweet spot between their needs and their budget.

City and highway performance

The EPA estimates for the 2018 Ram 1500 EcoDiesel are 20 MPG in the city and 27 MPG on the highway. The highway figure is where this truck shines, making it a capable and reasonably economical choice for long-distance drives. The eight-speed automatic transmission helps keep the engine running efficiently at cruising speeds. Stop-and-go city driving, however, takes a toll, as the weight of the truck and the power required to get it moving impact fuel consumption. Pay attention to driving style; smooth acceleration and anticipating traffic flow will make a difference in urban environments.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,400 for the 2018 Ram 1500 2WD EcoDiesel. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary based on your driving habits, the type of driving you do (city vs. highway), and fuel prices in your area. Someone who primarily uses the truck for highway commuting will likely see a lower annual cost, while someone who spends most of their time in stop-and-go traffic will probably exceed the $2,400 estimate. This also assumes standard diesel fuel prices; using premium diesel or fuel additives will also impact your overall expenditure.

Real-world expectations

While the EPA provides standardized estimates, real-world fuel economy often differs. Factors such as driving style, load weight, tire pressure, and weather conditions can significantly impact the MPG you achieve. Aggressive acceleration, frequent hard braking, and carrying heavy loads will all reduce fuel economy. Cold weather can also decrease efficiency as the engine works harder to maintain optimal operating temperature.

Many owners of the 2018 Ram 1500 EcoDiesel report figures close to the EPA estimates when driving conservatively, with some even exceeding the highway MPG on long trips. Meticulous maintenance, ensuring proper tire inflation, and minimizing aerodynamic drag (removing unnecessary roof racks, for example) can also help maximize your MPG.

How it compares

The 2018 Ram 1500 EcoDiesel’s fuel economy places it competitively within the half-ton truck segment. For example, the 2018 Ford F-150 with the 2.7L EcoBoost V6 (2WD) achieves an EPA-estimated 22 MPG combined. If you are looking to maximize fuel economy, the 2018 Chevrolet Colorado with the 2.8L diesel engine (2WD) achieves an EPA estimate of 25 MPG combined, although it is a smaller, mid-size truck. Comparing the 1500 MPG across all years shows how the EcoDiesel engine consistently delivers decent fuel efficiency compared to its gasoline counterparts. Understanding these differences is crucial for buyers weighing their priorities between payload, towing capacity, and fuel costs. For those exploring other options within the Ram family, reviewing all Ram fuel economy data can provide valuable insights.

Tips to maximize efficiency

Smooth and consistent acceleration can improve your fuel economy with the EcoDiesel. Avoid rapid starts and hard braking. Anticipate traffic flow and maintain a steady speed whenever possible. The engine is most efficient when operating at a constant load, so try to minimize sudden changes in speed.

Proper maintenance is important. Regular oil changes with the correct type of oil, and ensuring the air filter is clean, will keep the engine running at its peak. Check tire pressure regularly. Underinflated tires increase rolling resistance, which reduces fuel economy. Follow the manufacturer’s recommended tire pressure for optimal performance.

Reduce aerodynamic drag by removing any unnecessary items from the truck bed. Use a tonneau cover or a bed cap to improve airflow over the truck. Also, avoid carrying unnecessary weight in the bed or cab. Every extra pound adds to the engine’s workload and reduces fuel economy.

The EcoDiesel benefits from using cruise control on the highway. Maintaining a constant speed minimizes unnecessary fluctuations in throttle input, which can lead to improved fuel efficiency over long distances. However, be mindful of using cruise control in hilly terrain, as it can sometimes lead to excessive downshifting and reduced MPG.
