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.
