Capacity by Engine Option

Oil Change Interval

Routinely changing your 2021 Ram 1500's oil is critical for its longevity and performance. The onboard Oil Life Monitor (OLM) system dynamically adjusts the interval based on driving conditions. However, general guidelines are:

• Normal Duty: Up to 10,000 miles or 12 months, whichever comes first, as indicated by the OLM.
• Severe Duty: Every 5,000 miles or 6 months, whichever comes first. This applies if you frequently tow, idle for extended periods, drive in dusty conditions, or make short trips in extreme cold.

Always heed the illuminated "Change Engine Oil" or "Oil Change Required" message.

Drain Plug Torque

Proper drain plug torque prevents leaks and damage to the oil pan. Always replace the drain plug crush washer with a new one during every oil change to ensure a proper seal.

• 3.6L Pentastar V6: 20 ft-lbs (27 Nm)
• 5.7L HEMI V8: 25 ft-lbs (34 Nm)
• 3.0L EcoDiesel V6: 20 ft-lbs (27 Nm)

How to Change the Oil

Changing the oil on your 2021 Ram 1500 is a straightforward process:

1. Gather Supplies: New oil, oil filter, drain pan, wrench for drain plug, oil filter wrench, funnel, new crush washer, rags.
2. Warm Up Engine (Slightly): Drive for 5-10 minutes to warm the oil, allowing it to drain more easily. Do not overheat.
3. Lift and Secure Vehicle: Use a jack and jack stands, or ramps, to safely elevate the front of the truck.
4. Locate Drain Plug: Place the drain pan underneath. Remove the drain plug with a wrench and allow all oil to drain. Inspect the old crush washer.
5. Replace Drain Plug: Install the new crush washer and reinstall the drain plug, torquing it to the manufacturer's specification.
6. Remove Oil Filter: Position the drain pan to catch any drips. Use an oil filter wrench to remove the old filter. Ensure the rubber gasket from the old filter is not stuck to the engine block.
7. Install New Oil Filter: Apply a thin film of new oil to the rubber gasket of the new filter. Screw it on by hand until snug, then tighten an additional 3/4 to 1 full turn. Consult filter instructions for specific torque if provided.
8. Add New Oil: Using a funnel, add the recommended amount and type of new oil. Start with slightly less than the full capacity and check the dipstick.
9. Check Oil Level: Start the engine and let it run for a minute to circulate the oil. Shut off the engine, wait a few minutes, then check the oil level on the dipstick. Add more oil if needed.
10. Inspect for Leaks: Check around the drain plug and oil filter for any signs of leaks.
11. Reset Oil Life Monitor: Follow the procedure in your owner's manual to reset the OLM.

Common Issues / Tips for This Generation

• eTorque System: Vehicles equipped with the eTorque mild-hybrid system (3.6L V6 and 5.7L HEMI options) have specific oil requirements. While oil capacity remains consistent within engine families, always ensure the correct MS-6395 specification is met. The eTorque system itself does not significantly alter oil change procedures, but proper oil ensures optimal system performance.
• EcoDiesel Specifics: The 3.0L EcoDiesel V6 has very strict oil requirements (ACEA C3 and MS-11106). Using incorrect oil can lead to premature wear of emission control components, such as the Diesel Particulate Filter (DPF). Due to the high-pressure fuel system and turbocharger, premium quality synthetic oil is non-negotiable.
• Oil Filter Housing (3.6L V6): Pay attention to the plastic oil filter housing on the 3.6L Pentastar. Over-tightening can crack it, leading to oil leaks. Ensure the housing and cap are correctly seated and torqued.
• Oil Life Monitor (OLM): Do not ignore your truck's OLM. It's a sophisticated system designed to optimize oil change intervals based on your driving habits, helping to reduce unnecessary waste while protecting your engine. However, do not exceed 12 months, even if the OLM indicates more time.
