Capacity by engine option

Oil change interval

For most driving conditions, the recommended oil change interval for a 2021 Jeep Grand Cherokee is 10,000 miles or 12 months, whichever comes first.

However, if you frequently operate your vehicle under severe duty conditions, such as:

• Frequent short trips (less than 10 miles)
• Driving in dusty conditions
• Towing or hauling heavy loads
• Idling for extended periods
• Operating in extreme temperatures (very hot or very cold)

Chrysler recommends more frequent oil changes, typically every 5,000 miles or 6 months. Always refer to your owner's manual for the most accurate and up-to-date maintenance schedule.

Drain plug torque

For all engine options, the recommended drain plug torque for the 2021 Jeep Grand Cherokee is 20 ft-lbs (27 Nm). It is highly recommended to replace the drain plug crush washer with a new one during every oil change to prevent leaks. The crush washer helps create a secure seal.

How to change the oil

1. Warm up the engine: Drive the vehicle for a few minutes to bring the oil to operating temperature, ensuring it drains more completely.
2. Lift and secure: Safely lift the front of the vehicle using a jack and secure it with jack stands. Ensure the vehicle is level or slightly raised at the front for optimal draining.
3. Locate drain plug: Place a suitable drain pan beneath the oil pan. Locate the oil pan drain plug.
4. Drain oil: Carefully remove the drain plug, allowing the old oil to drain completely. Be cautious, as the oil will be hot.
5. Replace drain plug: Once drained, clean the drain plug and install a new crush washer. Reinstall the drain plug and torque it to 20 ft-lbs (27 Nm).
6. Remove old filter: Locate the oil filter (cartridge type for the V6 and some V8s, spin-on for others). Use an appropriate oil filter wrench to remove it. Be prepared for some residual oil to spill.
7. Install new filter: Apply a thin film of new engine oil to the gasket of the new oil filter (if spin-on). For cartridge filters, ensure the new O-rings are properly seated. Install the new filter and tighten it according to the manufacturer's specifications (usually hand-tight plus a quarter to half turn, or to a specific torque for cartridge filters).
8. Add new oil: Lower the vehicle. Remove the oil filler cap and carefully add the recommended amount and type of new engine oil.
9. Check oil level: Start the engine and let it run for a minute or two to circulate the new oil. Shut off the engine, wait a few minutes, and then check the oil level using the dipstick. Add more oil if necessary.
10. Inspect for leaks: Check thoroughly for any leaks around the drain plug and oil filter.

Common issues / tips

• 3.6L V6 (Pentastar) Oil Filter Adapter Leaks: The 3.6L Pentastar engine found in many Grand Cherokees is known for potential oil cooler/filter housing leaks, typically appearing around 60,000 to 100,000 miles. Be vigilant for oil drips around the top-rear of the engine near the intake manifold. This is a plastic component that can crack or warp over time. When changing the oil filter, ensure the cap is tightened correctly and the O-rings are properly seated.
• Using Correct Oil Spec: Always use engine oil that meets the specified Chrysler MS-6395 (for 3.6L/5.7L) or MS-12633 (for 6.4L) standards. Using incorrect oil can lead to premature engine wear and potential warranty issues.
• Engine Sludge (Older Generations): While less common in the WK2 generation (2011-2021) compared to earlier models, consistent use of conventional oil or extended oil change intervals can contribute to engine sludge. Adhere to recommended synthetic or synthetic blend oils and change intervals to prevent this.
• Hemi Tick (5.7L/6.4L V8): Some 5.7L and 6.4L Hemi engines can develop a valvetrain noise known as the "Hemi Tick." While often not immediately critical, it can sometimes be exacerbated by incorrect oil viscosity or low oil levels. Regular oil changes with the correct spec oil can help maintain optimal valvetrain health.
