Capacity by engine option

Oil change interval

• Normal Duty (Gasoline Engines): Generally, every 8,000 to 10,000 miles or 12 months, whichever comes first. Always refer to your owner's manual for the most accurate information or the vehicle's oil life monitoring system.
• Severe Duty (Gasoline Engines): If you frequently tow, haul heavy loads, drive in extreme temperatures, idle excessively, or drive on dusty roads, change your oil every 4,000 to 5,000 miles or 6 months.
• 6.7L Cummins Turbo Diesel: Typically every 15,000 miles or 12 months under normal conditions, or as indicated by the oil life monitor. Under severe duty (heavy towing, frequent idling, dusty conditions), intervals may be reduced to 7,500 miles or 6 months.

Drain plug torque

• 5.7L & 6.4L HEMI V8: 25 ft-lbs (34 Nm). Always use a new crush washer to ensure a proper seal and prevent leaks. The crush washer is usually included with a new oil filter or can be purchased separately.
• 6.7L Cummins Turbo Diesel: 18 ft-lbs (24 Nm). While some sources quote higher, 18 ft-lbs is often recommended for the Cummins engine to prevent over-tightening. Always use a new crush washer.

How to change the oil

1. Gather Supplies: Ensure you have the correct oil, oil filter, drain pan, wrench, torque wrench, and safety glasses.
2. Warm Up Engine (Optional but Recommended): Run the engine for a few minutes to warm the oil, making it flow more easily.
3. Lift and Secure Vehicle: Use a jack and jack stands to safely raise the front of the truck. Ensure it's stable.
4. Locate Drain Plug and Drain Oil: Place the drain pan under the oil pan. Carefully remove the drain plug with a wrench and allow all the old oil to drain completely.
5. Replace Drain Plug: Once drained, replace the drain plug with a new crush washer and tighten to the specified torque.
6. Replace Oil Filter: Locate the oil filter. Unscrew the old filter (a filter wrench may be needed). Apply a thin layer of new oil to the gasket of the new filter. Screw on the new filter by hand until snug, then tighten an additional 3/4 to 1 full turn (or follow filter manufacturer's instructions).
7. Add New Oil: Refer to the "Capacity by engine option" table and add the recommended amount of new oil through the filler cap.
8. Check Oil Level: Start the engine and let it run for a minute. Check for leaks around the drain plug and filter. Turn off the engine, wait a few minutes for the oil to settle, and then check the oil level with the dipstick. Add more oil if necessary.
9. Dispose of Old Oil: Properly dispose of the old engine oil at a recycling center.

Common issues / tips

• Hemi Tick (5.7L/6.4L): While not exclusively oil-related, using the correct 5W-20 oil and maintaining regular oil changes can help mitigate or prevent the "Hemi tick" often associated with lifter and camshaft wear. Using a higher-quality synthetic oil can also be beneficial.
• Diesel Particulate Filter (DPF) (6.7L Cummins): The 6.7L Cummins diesel engine is equipped with a DPF. Using the specified CJ-4 or CK-4 diesel oil is crucial. These oils have lower ash content, which helps prevent DPF clogging and costly repairs. Using the wrong oil can severely damage the DPF and catalytic converter.
• Oil Filter Housing Leaks (Hemi): Some Ram trucks with Hemi engines may experience leaks from the oil filter housing. If you notice oil around this area, it might be a cracked housing or a failing gasket, which should be addressed promptly.
• Choose Quality Filters: While aftermarket filters are listed, always opt for reputable brands. A quality oil filter is just as important as quality oil in protecting your engine.
