2020 Jeep Grand Cherokee Oil Capacity, Filter & Specs

The 2020 Jeep Grand Cherokee takes between 5.0 and 7.0 quarts of oil depending on the engine, with the popular 3.6L V6 requiring exactly 5.0 quarts (4.7 liters) of 0W-20 oil. As an ASE-certified master technician, I've serviced countless WK2 Grand Cherokees, and keeping up with the exact fluid and filter specifications is crucial to the longevity of these engines—especially the Pentastar V6 and Hemi V8s.

Below is your complete guide to the oil capacity, weights, filter part numbers, and torque specs for the 2020 Jeep Grand Cherokee.

Quick answer: 3.6L V6 Specs

Because the 3.6L Pentastar V6 is the most common engine in the 2020 Grand Cherokee, here is the quick reference for that specific powertrain:

• Oil Capacity: 5.0 quarts (4.7L) with filter change
• Recommended Weight: 0W-20
• Oil Specification: API SN/SP, Chrysler MS-6395
• OEM Oil Filter: Mopar MO-349 (Part # 68191349AA)
• Aftermarket Filters: Fram CH11665, WIX WL10010, Mobil 1 M1C-254A

(Note: If you have a V8 model, see the table below for your specific requirements).

Capacity by engine option

The 2020 Grand Cherokee was offered with several powertrains, ranging from the standard V6 to the supercharged Trackhawk V8.

Oil change interval

Jeep uses an automatic Oil Life Indicator system, but you should never exceed the maximum intervals:

• Normal Duty: Up to 10,000 miles or 12 months, whichever comes first.
• Severe Duty: 4,000 to 5,000 miles or 6 months. Severe duty applies if you frequently tow, drive off-road, idle extensively, or make mostly short trips in freezing temperatures.

Drain plug torque

• 3.6L V6: 20 ft-lbs (27 Nm)
• 5.7L / 6.4L / 6.2L V8: 25 ft-lbs (34 Nm)
• Crush Washer Note: The drain plug features a rubber/metal sealing washer. Inspect it closely. If the rubber is torn, flattened, or missing, replace the drain plug or the gasket (if available separately) to prevent leaks.

How to change the oil

1. Warm the engine: Run the vehicle for a few minutes to warm the oil, which helps it drain faster and suspend contaminants.
2. Access the filter and plug: For the 3.6L V6, the oil filter is a cartridge style located under the hood on top of the engine. Use a 24mm socket to loosen the cap. For V8 models, the spin-on filter is located underneath.
3. Drain the oil: Remove the 13mm drain plug from the oil pan and let the oil drain completely into a catch pan.
4. Replace the filter: For the V6, swap the paper cartridge and snap the new one into the cap. Always replace the O-ring on the cap and lubricate it with fresh oil. Torque the cap to 18 ft-lbs (25 Nm) – do not overtighten! For V8s, install the new spin-on filter hand-tight.
5. Reinstall drain plug: Install the plug and torque to the spec listed above.
6. Refill and check: Add the specified amount of oil. Start the engine, check for leaks, shut it off, and verify the fluid level on the dipstick after letting it sit for 5 minutes.
7. Reset Oil Life: Turn the ignition to ON/RUN (engine off), fully depress the accelerator pedal three times within 10 seconds, and turn the ignition off.

Common issues / tips

For this specific generation (WK2), there is one major issue every DIYer needs to know about: the 3.6L Pentastar oil filter housing/cooler assembly. The housing is made of plastic and sits deep in the valley of the engine. Overtightening the 24mm oil filter cap is the number one cause of cracking this housing. Once cracked, oil will pool in the engine valley and aggressively leak down the back of the engine and transmission. Always use a torque wrench on the plastic filter cap (18 ft-lbs max) to avoid a very expensive repair bill.
