How Often Does a 6.7 Cummins Need an Oil Change?

The Cummins 6.7L engine is one of the most reliable diesels on the market. It’s known for its high performance and durability, and many owners report getting 250,000 miles or more out of their trucks before needing any major repairs. One of the keys to keeping your 6.7L Cummins running strong is regular maintenance, including changing the oil and filter according to the factory recommended schedule.

Depending on how you use your truck, that schedule may be different than what’s listed in the owner’s manual. For example, if you do a lot of stop-and-go driving in hot weather, tow heavy loads frequently or drive in dustier conditions, you may need to change your oil more often than someone who uses their truck primarily for highway driving in cooler temperatures. Consult your owner’s manual or talk to your service advisor at your local Cummins dealership to find out what oil change interval is right for your truck and driving habits.
