Engine Oil
6.7L Cummins Diesel: For the 2016 Ram 3500 equipped with the 6.7L Cummins Turbo Diesel engine, the manufacturer specifies an engine oil meeting Chrysler Material Standard MS-10902. The recommended viscosity is SAE 5W-40. It is crucial to use oil specifically designed for diesel engines, labeled with an API CJ-4 or newer rating. Using an incorrect oil type can lead to accelerated wear and damage to emission control systems. The oil capacity is approximately 12.0 quarts with a filter change.
5.7L Hemi V8: For the 5.7L Hemi engine, the factory recommendation is SAE 5W-20 engine oil, meeting Chrysler Material Standard MS-6395. Look for oils with an API SN Plus or SP rating for optimal protection against low-speed pre-ignition (LSPI). The oil capacity is around 7.0 quarts with a filter change.
6.4L Hemi V8: The 6.4L Hemi engine in the 2016 Ram 3500 requires SAE 0W-40 engine oil, also meeting Chrysler Material Standard MS-12633. As with the 5.7L Hemi, an API SN Plus or SP rating is preferred. The oil capacity is approximately 7.0 quarts with a filter change.
Intervals: Generally, engine oil and filter changes are recommended every 10,000 miles or 12 months for the Cummins diesel, and every 10,000 miles or 12 months for the Hemi engines, whichever comes first. However, severe duty cycles, such as heavy towing, dusty conditions, or frequent short trips, may necessitate more frequent changes. Always refer to your owner's manual for the most accurate and personalized maintenance schedule based on your driving conditions.
Engine Coolant
The 2016 Ram 3500 utilizes Mopar Organic Additive Technology (OAT) Antifreeze/Coolant, which is typically purple or magenta in color. The specified Mopar part number is 68163848AA, and it meets Chrysler Material Standard MS-12106. This OAT coolant is designed for a 10-year or 150,000-mile service life. It is critical to use only OAT coolant in your Ram 3500. Mixing OAT coolant with other types, such as Hybrid Organic Additive Technology (HOAT) or Inorganic Additive Technology (IAT) coolants, can lead to chemical reactions, gel formation, and severe damage to the cooling system and engine components. Always perform a complete flush and refill if switching coolant types (which is not recommended unless absolutely necessary).
