2014 Ram 1500 EcoDiesel Outdoorsman Crew Cab 4x4 Update 3
Fuel-Efficient Truck Still Sweating the Details
Just five months after arriving in the Motor Trend Garage, our 2014 Ram 1500 EcoDiesel Outdoorsman Crew Cab 4x4 pickup’s odometer has traveled from 666 miles to more than 15,000 miles. Although we’ve enjoyed having a full-size four-door truck in the fleet, we have had a few issues with our diesel-powered Ram pickup.
All our air-conditioning woes have been cured, but our 2014 Ram 1500 EcoDiesel’s check engine light illuminated just before the 15,000-mile mark. A trip to the dealer indicated that one of the emission system’s NOX sensors was “below threshold.” A few days later we got our Ram 1500 EcoDiesel back with a new catalytic converter. No possible culprit for the issue was provided.
Like most new diesel engines, the Ram 1500 EcoDiesel is equipped with an after-cat exhaust treatment to improve emissions. At around the 7,000-mile and 15,000-mile marks, our Ram’s diesel exhaust fluid (DEF) needed to be refilled. In addition to the DEF-level gauge, the cluster-mounted information screen indicates how many miles the vehicle can be driven when the fluid is getting low. Once the fluid reaches a critical level, the computer won’t allow the engine to start. A trip to the local auto parts store and five gallons of DEF at $10.99 each set us back about $55 each refill.
Since arriving, the Ram 1500 EcoDiesel has been on several road trips, including three to the Rocky Mountains at more than 1,500 miles each time. With its 26-gallon fuel tank and a 19/27 mpg city/highway EPA rating (20/28 mpg in our RealMPG testing), the Ram 1500 EcoDiesel regularly travels 425-550 miles between fuel stops. On one particular leg of a road trip, the Ram 1500 EcoDiesel managed to go more than 600 miles on one tank, averaging 26 mpg at speeds 5-10 mph above posted limits. The low-fuel light comes on when there is still about three to four gallons of fuel in the tank.
