15 MPG combined is the reality for anyone considering a 2015 Ram 1500 4WD with the 5.7L Hemi V8. This isn’t a fuel sipper. It’s a truck built for hauling, towing, and enduring tough conditions, and for many buyers, that capability is worth the fuel cost. These buyers prioritize brute force and dependability over saving money at the gas station, from construction crews to weekenders with boats or campers.

City and highway performance

The EPA estimates paint a picture of the Ram 1500’s fuel consumption. Around town, expect around 13 MPG. This number reflects stop-and-go traffic and the engine’s effort to move this heavy vehicle. Highway driving offers a slight improvement, with a rating of 19 MPG. While 19 MPG is achievable on long, flat stretches, any incline or headwind will reduce that number. Even slight increases in speed over 65 mph can significantly affect your highway MPG.

Annual fuel cost

Budget accordingly, because the EPA estimates an annual fuel cost of approximately $3,500. This calculation assumes 15,000 miles of driving per year and the EPA’s estimate of national average fuel prices. Prices can fluctuate. If you drive more, live in an area with higher gas prices, or do a lot of heavy towing, your actual costs will be higher. Understanding the priorities of the Ram 1500 4WD buyer is critical. They’re willing to shoulder this cost for the capability the truck offers.

Real-world expectations

While the EPA numbers provide a benchmark, real-world fuel economy can vary. Factors such as driving style, tire size, ambient temperature, and payload all have an impact. Owners who frequently tow or haul heavy loads should expect to see numbers below the EPA estimates. Those who stick to mostly highway driving and avoid aggressive acceleration might get closer to the 19 MPG figure, although exceeding it will be difficult. Drive conservatively and maintain the vehicle properly.

How it compares

The 2015 Ram 1500 4WD with the 5.7L V8 isn’t winning any fuel economy contests. Its closest competitors, like the Chevrolet Silverado 1500 4WD with the 5.3L V8 (rated at 16 MPG combined) and the Ford F-150 4WD with the 5.0L V8 (also 16 MPG combined), offer slightly better numbers. Even the Toyota Tundra 4WD with its 5.7L V8, a known gas-guzzler, achieves around 14 MPG combined. The differences are not huge, but worth considering. Some buyers prioritize the Ram’s styling, interior features, or specific capabilities over these minor fuel economy gains, while others might find the slightly better MPG of a Silverado appealing. Remember to check 1500 MPG across all years for different configurations that may improve economy.

Tips to maximize efficiency

First, drive smoothly. The Hemi V8 is responsive, so avoid aggressive acceleration and hard braking. Anticipating traffic flow and maintaining a steady speed will improve your MPG. This engine is powerful, which makes it easy to be heavy on the gas pedal. Be gentle.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure and inflate them to the recommended PSI (pounds per square inch) found on the sticker inside the driver’s side door. Even a small difference can negatively impact your gas mileage.

Reduce unnecessary weight. Hauling around extra cargo in the bed of your truck or in the cab adds weight, which reduces fuel efficiency. Remove any unnecessary items and only carry what you need for each trip. Remove any roof racks or carriers when they are not in use, as they create aerodynamic drag.

Regular maintenance is key. A well-maintained engine runs more efficiently. Follow the manufacturer’s recommended maintenance schedule, including oil changes, air filter replacements, and spark plug inspections. Addressing small issues promptly can prevent them from becoming bigger, more fuel-intensive problems. Check all Ram fuel economy data before your next maintenance appointment so you’re prepared.

Consider your use case carefully. If you primarily use your Ram 1500 for commuting or light-duty tasks, you might explore alternative models or powertrains. While the 5.7L Hemi is a capable engine, it may not be the most efficient choice for everyday driving. A smaller engine, if it meets your needs, will likely provide better fuel economy.
