2014 Ram 1500 EcoDiesel: July Fuel Economy Yields Worst Tank Yet

August 5, 2015

2014 Ram 1500 EcoDiesel

July was a big month for our long-term 2014 Ram 1500 EcoDiesel as it towed a trailer across the United States. The truck did a great job pulling the heavy load, but expectedly, fuel economy suffered.

In the last four weeks, the Ram traveled 4,415 miles, towing for 2,400 of those miles. It used 224.3 gallons of diesel during July for an average of 19.7 mpg. While towing a 5,000-pound load (more on that later), the Ram averaged 17.5 mpg. All of that towing dropped average lifetime MPG from 22.5 to 22.1.

While towing across Texas, the Ram got its worst tank yet of 15.1 mpg, a 2-mpg drop from the previous worst. This was due to the heavy load behind it and varied speed limits on Texas's B-Roads. The limit decreases from 75 to 65, 55, 45, 35 and 25 mph through several small towns. Exiting these towns, the speed limit climbs back up to 75 mph. Basically, it was like driving on and off freeway ramps several dozen times.

Even with several thousand miles of towing under its belt, the Ram is still beating the EPA's combined fuel economy estimate. Now, if it could just teach that trick to our Ford.

Worst Fill MPG: 15.1
Best Fill MPG: 27.9
Average Lifetime MPG: 22.1 
EPA MPG Rating: 22 Combined (19 city/27 highway)
Best Range: 700.2
Current Odometer: 37,623 miles
