2014 Ram 1500 EcoDiesel: Fuel Economy Update for October — First Drop Below EPA Combined Rating

by Josh Jacquot, Senior Editor on November 10, 2015

2014 Ram 1500 EcoDiesel

We put another 1,883 miles on our 2014 Ram 1500 EcoDiesel in October. More than 800 of those miles involved towing, which helped drag the Ram's lifetime average fuel economy (21.6 mpg) below the EPA's combined estimate (22 mpg) for the first time in our test.

With only 2,000 miles on our truck, the lifetime average was almost 23 mpg (22.9, actually) and it has slowly decreased since. With one notable exception, the Ram often averages 18 or 19 mpg when towing. Still, averaging so near the EPA number is impressive for a vehicle that tows so frequently. Most of our long-termers finish their time with us at a lifetime average below the EPA combined number. And most aren't tow vehicles.

Here are the numbers as we creep up on 50,000 miles:

Worst Fill MPG: 15.1
Best Fill MPG: 27.9
Average Lifetime MPG: 21.6 
EPA MPG Rating: 22 Combined (19 city/27 highway)
Best Range: 700.2
Current Odometer: 43,587 miles
