Engine oil and oil filter change intervals are set at 7,500 miles (12,070 km). 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 and has a maximum 1.00 mass % content of sulfated ash.

Also, 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.
