How Much Oil Does a 6.7 Cummins Take?
For nearly all Ram 2500 and 3500 trucks from 2007.5 onward, the 6.7 Cummins oil capacity is 12 quarts with a filter change. Some newer models and cab and chassis variants may differ, so always verify with your owner's manual. Use 15W-40 or 5W-40 synthetic oil meeting API CK-4 specs and quality filters like Fleetguard.
