The Cummins 6.7 engine is a powerful and reliable diesel engine used in various Ram trucks. One of the essential maintenance tasks for this engine is ensuring the correct oil capacity. In this article, we will provide you with the ultimate guide to Cummins 6.7 oil capacity, including the recommended oil type, capacity, and change interval.
Why Oil Capacity Matters
Maintaining the correct oil capacity in your Cummins 6.7 engine is crucial for its performance, efficiency, and longevity. Oil lubricates the engine's moving parts, prevents overheating, and cleans the engine by carrying dirt and debris to the oil filter. If the oil capacity is too low, the engine may experience increased wear and tear, leading to premature failure. On the other hand, excessive oil can cause engine damage, decreased fuel efficiency, and increased emissions.

The recommended oil type for the Cummins 6.7 engine is 15W-40 synthetic diesel engine oil. This type of oil provides excellent lubrication, wear protection, and fuel efficiency in both hot and cold temperatures. Some popular oil brands that meet the Cummins 6.7 engine's requirements include:- Cummins synthetic diesel engine oil
- Shell Rotella T4 15W-40
- Mobil Delvac 1 15W-40
