Capacity by Engine Option

Oil Change Interval

For most 2020 Jeep Wranglers, the oil change interval is dictated by the vehicle's Oil Change Indicator System. However, general guidelines are:

• Normal Duty: Every 7,500 – 10,000 miles or 12 months, whichever comes first.
• Severe Duty: Every 3,000 – 5,000 miles or 6 months, whichever comes first. Severe duty includes frequent short trips, extensive idling, towing, or driving in dusty conditions.

Always refer to your owner's manual for the most accurate and up-to-date recommendations for your specific driving conditions.

Drain Plug Torque

• 2.0L Hurricane Engine: 22 ft-lbs (30 Nm)
• 3.6L Pentastar V6 Engine: 20 ft-lbs (27 Nm)

It is highly recommended to replace the drain plug crush washer (gasket) with a new one every time you change the oil to prevent leaks. Consult your dealer for the correct OEM crush washer part number.

How to Change the Oil

1. Warm Up Engine: Drive the vehicle for a few minutes to warm the oil, allowing it to drain more easily.
2. Lift and Secure: Safely lift the front of the vehicle using a jack and secure it with jack stands.
3. Locate Drain Plug: Place a drain pan directly under the oil pan drain plug.
4. Drain Oil: Carefully remove the drain plug and allow all the old oil to drain completely.
5. Replace Drain Plug: Install a new crush washer on the drain plug and reinstall it, tightening to the specified torque.
6. Locate Oil Filter: Access and remove the old oil filter. For the 2.0L and 3.6L engines, the filter is a cartridge type located at the top of the engine.
7. Install New Filter: Lubricate the O-rings of the new filter with fresh oil and install it, ensuring it's properly seated and tightened according to manufacturer specifications (usually hand-tight plus a quarter turn).
8. Add New Oil: Fill the engine with the recommended type and amount of new oil.
9. Check Level: Start the engine, let it run briefly, then shut it off. Wait a few minutes for the oil to settle, then check the oil level with the dipstick and top off if necessary.
10. Reset Oil Life Monitor: Follow your vehicle's procedure to reset the oil life monitoring system.
11. Dispose of Old Oil: Properly dispose of used oil at an authorized recycling center.

Common Issues / Tips for this Generation (JL Wrangler)

• Oil Filter Housing (3.6L Pentastar): The plastic oil filter housing found on the 3.6L Pentastar engine can become brittle over time and may crack, leading to oil leaks. Inspect this area during oil changes. If replacing, consider an aftermarket aluminum housing for improved durability.
• 2.0L Turbo Oil Consumption: Some 2.0L turbocharged engines may exhibit slightly higher oil consumption. It's always a good practice to regularly check your oil level between changes, especially if you drive in challenging conditions.
• Correct Oil Spec is Crucial: Modern engines, including those in the 2020 Wrangler, are designed with specific oil viscosity and additive packages in mind. Using the incorrect oil can lead to premature wear and potential engine damage. Always adhere to the API SN PLUS or later specification for optimal protection, as these oils are formulated to prevent low-speed pre-ignition (LSPI), particularly important for turbocharged engines like the 2.0L Hurricane.
• Accessible Oil Filter: Both the 2.0L and 3.6L engines feature a top-mounted cartridge-style oil filter, which makes oil changes relatively easy compared to some vehicles with underslung canister filters.
