Capacity by Engine Option

Oil Change Interval

Your 2014 Ram 2500 is equipped with an oil life monitoring system. The system will display a "Change Oil" message when service is due. However, the maximum recommended interval varies by engine and usage.

• Normal Duty: For the 5.7L HEMI, do not exceed 10,000 miles or 1 year. For the 6.7L Cummins, the maximum interval is 15,000 miles or 6 months.
• Severe Duty: If you frequently tow heavy loads, operate in dusty conditions or extreme temperatures, or do a lot of idling, follow the severe service schedule. This typically means changing the oil every 4,000-5,000 miles for the HEMI and every 7,500 miles for the Cummins.

Drain Plug Torque & Crush Washer

Properly tightening the drain plug is critical to prevent leaks.

• 5.7L HEMI V8: 25 ft-lbs (34 N·m). This engine uses a reusable rubber gasket on the drain plug. Inspect it for damage and replace if necessary.
• 6.7L Cummins Diesel: 37 ft-lbs (50 N·m). It is recommended to use a new crush washer with each oil change. Consult your dealer for the correct part number.

How to Change the Oil (Simplified)

1. Run the engine for 2-3 minutes to warm the oil.
2. Place a drain pan under the oil pan and remove the drain plug.
3. While the oil drains, remove the oil filter. Be prepared for some oil spillage.
4. Wipe the filter mounting surface clean and apply a thin coat of new oil to the gasket of the new filter.
5. Install the new filter and tighten it hand-tight plus an additional quarter-turn.
6. Reinstall the oil drain plug with a new washer (if applicable) and torque to spec.
7. Fill the engine with the correct amount and type of new oil.
8. Start the engine, let it run for 30 seconds, shut it off, and re-check the oil level, topping up as needed.
9. Reset the oil life monitor through the instrument cluster menu.

Common Issues & Tips for 2013-2018 Ram HD

• 5.7L HEMI "Tick": Some owners report a ticking sound, often caused by lifter and camshaft wear. Using high-quality oil that meets the MS-6395 spec and following proper change intervals is critical.
• 6.7L Cummins Fuel Dilution: On diesel models, monitor your oil level between changes. A rising oil level can indicate fuel is mixing with the oil, often a byproduct of the DPF regeneration process. If you notice this, shorten your change interval. Using a high-quality CJ-4 or CK-4 oil helps combat the effects of dilution.
• Filter Access: On the 6.7L Cummins, the oil filter is large and located on the passenger side of the engine block. Access can be tight, and a good filter wrench is essential. For the 5.7L HEMI, the filter is at the front of the engine and is relatively easy to access.
