Capacity by Engine Option

Oil Change Interval

• Normal Duty: For the 6.4L HEMI, typically 8,000 to 10,000 miles or 12 months, whichever comes first. For the 6.7L Cummins, typically 15,000 miles or 12 months, whichever comes first, though some heavy-duty usage or specific applications might recommend sooner.
• Severe Duty: This includes frequent short trips, extensive idling, towing heavy loads, off-road driving, or extreme temperatures. For both engines, consider shortening the oil change interval to 4,000-5,000 miles or 6 months.

Drain Plug Torque

• 6.4L HEMI V8: 20 ft-lbs (27 Nm)
• 6.7L Cummins Turbo Diesel: 18 ft-lbs (24 Nm)

Always use a new crush washer or drain plug gasket with every oil change to prevent leaks. These are typically copper or fiber for the HEMI, and often a bonded washer for the Cummins.

How to Change the Oil

1. Gather your tools: new oil, new oil filter(s), drain pan, wrench for the drain plug, oil filter wrench, torque wrench, and safety glasses.
2. Warm up the engine slightly for better oil flow, then turn it off.
3. Locate the drain plug on the oil pan, place the drain pan underneath, and carefully remove the plug. Allow all the old oil to drain.
4. While the oil is draining, locate and remove the old oil filter(s). Be prepared for some oil to spill.
5. Apply a thin film of new oil to the rubber gasket of the new oil filter(s) and hand-tighten until snug, then turn an additional 3/4 to 1 full turn (or as per filter manufacturer instructions).
6. Once the old oil has fully drained, reinstall the drain plug with a new crush washer and torque it to the specified setting.
7. Fill the engine with the recommended amount and type of new oil. Start with slightly less than the full capacity and add as needed.
8. Start the engine and let it run for a few minutes to circulate the new oil. Check for any leaks around the drain plug and oil filter.
9. Turn off the engine, wait a few minutes, and then check the oil level on the dipstick. Add more oil if necessary to reach the "full" mark.

Common Issues / Tips

• 6.4L HEMI V8: These engines are known to consume some oil, so it's vital to check your oil level regularly between changes, especially if you drive aggressively or tow frequently. Using a high-quality synthetic oil can help minimize deposits.
• 6.7L Cummins Turbo Diesel: The 6.7L Cummins utilizes two fuel filters (primary and secondary) which are often serviced alongside oil changes. Ensure you are getting the correct oil filter for your application, as Cummins engines have specific requirements. The diesel particular filter (DPF) system on these trucks requires low-ash oil (API CK-4 or CJ-4) to prevent premature clogging and expensive repairs. Never use oils that do not meet these specifications.
