2014 Ram 1500 Ecodiesel: Fuel Economy Update for November

December 4, 2014

2014 Ram 1500 Ecodiesel

November was a busy month for our 2014 Ram 1500 EcoDiesel. Nearly 5,200 miles were added, and about half of them resulted from a Thanksgiving road trip to Oregon I still haven't told you very much about.

The above photograph hints at what was going on, for half the time, at least. Yes, I towed a trailer containing a rally car all the way back. You can't see from here, but the bed and cab are all loaded with tires and the contents of my eldest daughter's dorm room. And the wooden splash panel on the nose of the trailer is concealing a massive steel Jobox tool box filled with a few hundred pounds of spare car parts. The car itself is packed with more tires, three packed suitcases and trash bags full of clothes and bedding.

So it should come as no surprise that I reset the Ram's worst tank this month. After all, I towed the lot from Bend, Oregon over Santiam Pass to Eugene and then south along Interstate 5 over numerous other passes until we crested the Siskiyou Summit and rolled down into Yreka, California for a stretch and some more diesel fuel.

But that new "worst" tank was still a respectable 17.1 mpg. Not bad for towing in the mountains with what I figure is about 6,000 pounds of added weight, possibly more. And the subsequent all-towing tanks that finished the 1,040-mile trip home were 19.4 and 20.5 mpg.

It would seem that diesel pays its biggest dividends to those that tow.

But our Ram's average lifetime mpg didn't suffer overmuch from these three all-towing tanks. Sure, the overall sagged from 22.7 mpg a bit, but 22.4 mpg still bests our Ram 1500 Ecodiesel 4x4's EPA Combined rating of 22 mpg by a wee margin.

Worst Fill MPG: 17.1 (down from 17.5 mpg)
Best Fill MPG: 27.9
Average Lifetime MPG: 22.4 (4.5 gallons per 100 miles)
EPA MPG Rating: 22 Combined (19 City / 27 Highway)
Best Range: 700.2 miles
Current Odometer: 21,079 miles

Thing is, there are exactly zero towing miles in the EPA's test procedure. But between me and others on staff we can probably claim two or three thousand towing miles. I should probably add them up sometime.
