Capacity by Engine Option

The 2025 Ram 2500 offers two robust engine options, each with specific oil requirements:

Oil Change Interval

Regular oil changes are crucial for the longevity and performance of your 2025 Ram 2500. The recommended intervals vary based on driving conditions:

• Normal Duty: Under normal driving conditions, it is generally recommended to change the oil every 10,000 miles (16,000 km) or 12 months, whichever comes first, for both gasoline and diesel engines.
• Severe Duty: If your driving involves heavy towing, frequent off-road use, extreme temperatures, extensive idling, or short trips, your vehicle is operating under severe duty. In such cases, it's advisable to change the oil more frequently, typically every 5,000 miles (8,000 km) or 6 months, whichever comes first.

Always refer to your owner's manual for the most accurate and up-to-date service schedules.

Drain Plug Torque

Properly torquing the drain plug is essential to prevent leaks and avoid damage to the oil pan.

• 6.4L HEMI V8: The drain plug torque specification is typically 25 ft-lbs (34 Nm). Always use a new crush washer to ensure a proper seal.
• 6.7L Cummins Turbo Diesel: The drain plug torque specification is typically 30 ft-lbs (41 Nm). Always use a new crush washer with each oil change.

Consult your owner's manual or a service professional for the most precise torque specifications for your specific model.

How to Change the Oil

Changing the oil on your 2025 Ram 2500 is a straightforward maintenance task for the mechanically inclined. Here's a general outline:

1. Gather Supplies: Ensure you have the correct oil, oil filter, drain pan, wrench, torque wrench, and a new crush washer.
2. Warm Up Engine: Drive the truck for a few minutes to bring the engine oil to operating temperature, which helps the oil drain more completely.
3. 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.
4. Locate Drain Plug: Place the drain pan under the drain plug on the oil pan.
5. Remove Drain Plug: Carefully remove the drain plug and allow the oil to drain completely. Be cautious, as the oil will be hot.
6. Replace Filter: While the oil is draining, remove the old oil filter and install the new one. Apply a thin coat of new oil to the gasket of the new filter before installing.
7. Reinstall Drain Plug: Once the oil has fully drained, clean the drain plug and install a new crush washer. Reinstall the drain plug and tighten it to the manufacturer's specifications with a torque wrench.
8. Refill Oil: Lower the truck and refill the engine with the recommended amount and type of new oil. Use a funnel to avoid spills.
9. Check Level: Start the engine and let it run for a minute to circulate the new oil. Turn off the engine, wait a few minutes, and then check the oil level with the dipstick. Add more oil if necessary.
10. Dispose of Old Oil: Properly dispose of the old oil and filter at an authorized recycling center.

Common Issues / Tips for the 2025 Ram 2500 (5th Gen)

• Diesel Exhaust Fluid (DEF): For 6.7L Cummins owners, remember to monitor and refill your DEF tank regularly. Low DEF will limit engine power and eventually prevent the truck from starting.
• Fuel Filter Maintenance (Diesel): Diesel engines also require regular fuel filter changes. Consult your owner's manual for the recommended interval, usually every 15,000-20,000 miles.
• Oil Life Monitoring System: The 2025 Ram 2500 is equipped with an Oil Life Monitoring (OLM) system. While this system can be helpful, it's still wise to adhere to the severe duty interval if you engage in demanding activities.
• Cold Weather Operation (Diesel): If you operate your 6.7L Cummins in consistently cold climates (below 0°F / -18°C), consider using a 5W-40 synthetic diesel engine oil for easier cold starts and better lubrication. Ensure your block heater is functioning correctly.
• High-Mileage Considerations: As your Ram 2500 accumulates miles, it's even more critical to stick to regular maintenance schedules and monitor for any unusual oil consumption or leaks.
