6.7L Cummins Turbo Diesel for Pickups (2013)

The Model Year (MY) 2013.5+ lineup of Ram Trucks powered by the 6.7L Cummins Turbo Diesel is here. This year’s lineup includes many new features our customers asked for.

For MY 2013.5+, the 6.7L Cummins Turbo Diesel horsepower and torque ratings are increased across the board. The new high-output engine boasts 385 hp and 900 lb-ft of best-in-class torque. This results in an increase of 50 lb-ft over the competition. Here’s a summary of the 2016 ratings.

Ram also reduces operating costs with a new Selective Catalytic Reduction (SCR) aftertreatment that uses Diesel Exhaust Fluid (DEF). This helps contribute to a 10 percent increase in fuel economy while delivering a best-in-class 15,000-mile oil-change interval. Doubling the oil-change interval has a direct link to your operating costs, and will help to keep a little of your hard-earned money in your pocket.

Diesel owners will also benefit from a new cooling system that affords 25 percent more heat-rejection capacity. This is done via a high-efficiency fan, dual radiators, dual transmission coolers and a charge-air cooler, all of which lower operating temperatures and deliver improved performance.

Also improved for 2013 is the biofuel capability. The MY 2013.5+ engine is B20-capable, whereas the 2012 engine was only B5-capable – adding flexibility at the pump. Now you have the option to use ultra-low-sulfur diesel or up to B20 biodiesel, where available.

Another feature is the “smart” exhaust brake. The VGT™ Variable Geometry Turbo is enhanced for 2013 through the addition of a brake feature that electronically controls the exhaust braking to maintain a set vehicle speed while descending a grade.

Maintenance intervals have changed over the years on several items, however, the valve lash adjustment remains the same at 150,000 miles (240,000 km) and the fuel filter replacement remains at 15,000 miles (24,000 km). The oil change interval is 15,000 miles (24,000 km) and is duty cycle based. This engine uses an oil change monitoring system which will display a message on the vehicle information center that alerts the driver to change the oil.

Don't forget that your new Cummins 6.7L Turbo Diesel engine requires low-ash engine oil; failure to use this type of oil can result in serious damage to the exhaust aftertreatment system in your vehicle. Be sure to purchase engine oil that meets CES 20081 standards.

Due to the new EPA regulations, owners of MY07 and later Cummins 6.7L turbo diesel-powered highway vehicles must refuel only with Ultra-Low Sulfur Diesel (ULSD) fuel meeting a 15-ppm on-highway requirement. Use of all other fuels is prohibited and may result in damage to the engine and/or the aftertreatment system. Be sure to purchase your diesel fuel from a reputable fuel station. For most year-round service, a high-quality No. 2 diesel fuel that meets ASTM specification D-975 (0.0015% sulfur level) will maintain good performance. EPA requires retail fuel stations that carry and dispense LSD and ULSD to label the pumps with a Low-Sulfur Highway Diesel Fuel and an Ultra-Low Sulfur Diesel label.

In addition, diesel fuel sold for off-highway use should not be used in any Cummins turbo diesel engine. This is due to off-highway fuels not necessarily meeting the fuel cleanliness or lubricity requirements for on-highway fuel specifications. Use of such off-highway fuels can result in accelerated wear to fuel system components.
