Capacity by Engine Option

Oil Change Interval

The oil change interval for your 2020 Ram 2500 varies based on your driving conditions:

• Normal Duty: For the 6.4L HEMI V8, Mopar recommends changing the oil every 10,000 miles or 12 months, whichever comes first. For the 6.7L Cummins Diesel, normal duty is typically 15,000 miles or 12 months.
• Severe Duty: If you frequently tow heavy loads, drive in extreme temperatures, operate in dusty conditions, or make frequent short trips, your vehicle is considered to be under severe duty. In these cases, it is highly recommended to shorten the oil change interval to 5,000 miles or 6 months for the 6.4L HEMI and 7,500 miles or 6 months for the 6.7L Cummins. Always consult your owner's manual for the most accurate and up-to-date information.

Drain Plug Torque

• 6.4L HEMI V8: The oil drain plug torque is typically 25 ft-lbs (34 Nm). Always use a new crush washer to prevent leaks.
• 6.7L Cummins Diesel: The oil drain plug torque is typically 30 ft-lbs (41 Nm). Always use a new crush washer.

How to Change the Oil

1. Warm Up Engine: Drive the truck for a few minutes to warm the oil, allowing it to drain more easily.
2. Lift and Secure: Safely lift the front of the truck using a jack and secure it with jack stands. Never work under a vehicle supported only by a jack.
3. Locate Drain Plug: Place a suitable drain pan beneath the oil pan.
4. Drain Oil: Carefully remove the drain plug and allow all the old oil to drain completely. Inspect the drain plug and replace the crush washer.
5. Replace Filter: Remove the old oil filter. Apply a thin coat of new oil to the gasket of the new filter before screwing it on. Hand-tighten until snug, then turn an additional 3/4 to 1 full turn (refer to filter instructions).
6. Refill Oil: Replace the drain plug and torque to spec. Refill the engine with the recommended type and amount of new oil.
7. Check Level: Start the engine and let it run for a few minutes. Check for leaks. Turn off the engine, wait a few minutes, then check the oil level on the dipstick and top off if necessary.
8. Dispose: Properly dispose of the used oil and filter at an authorized recycling center.

Common Issues / Tips

• 6.4L HEMI: Some owners have reported higher-than-normal oil consumption, especially when new. Monitor your oil level regularly between changes. Using a high-quality synthetic oil can help reduce this. Ensure you use the correct 0W-20 viscosity.
• 6.7L Cummins: These engines are known for their durability. However, proper maintenance, especially timely oil changes with the correct API CK-4 spec oil, is critical for the longevity of the turbocharger and emission systems. The cartridge-style oil filter can be a bit messier to change than spin-on types, so be prepared with plenty of rags.
• Always check your owner's manual for the most precise and up-to-date specifications for your specific vehicle configuration.
