Capacity by Engine Option

Oil Change Interval

Jeep recommends adhering to the following oil change intervals for your 2020 Gladiator:

• Normal Duty: Change oil and filter every 10,000 miles (16,000 km) or 12 months, whichever comes first.
• Severe Duty: If you frequently drive in dusty conditions, tow heavy loads, drive extensively at idle or low speeds, or regularly take short trips in freezing temperatures, a more frequent interval of 5,000 miles (8,000 km) or 6 months is recommended. Always refer to your owner's manual and the vehicle's Oil Change Indicator System for the most accurate guidance.

Drain Plug Torque

The oil drain plug on the 2020 Jeep Gladiator (3.6L Pentastar V6) should be tightened to 20 ft-lbs (27 Nm). Always use a new crush washer with each oil change to ensure a proper seal and prevent leaks. The OEM crush washer is typically a metal gasket.

How to Change the Oil

Changing the oil on your 2020 Jeep Gladiator is a straightforward process:

1. Safely lift and support the front of the vehicle using a jack and jack stands.
2. Locate the oil drain plug on the oil pan, positioned at the bottom of the engine.
3. Place a suitable drain pan underneath the plug. Loosen and remove the drain plug, allowing the old oil to drain completely.
4. 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).
5. Locate the spin-on oil filter. Place a small drain pan beneath it to catch any drips, then unscrew the old filter. Be prepared for some oil spillage.
6. Apply a thin film of new oil to the rubber gasket of the new oil filter. Screw on the new filter by hand until snug, then turn an additional 3/4 to 1 full turn. Do not overtighten.
7. Lower the vehicle safely.
8. Remove the engine oil fill cap and add 6 quarts of fresh 0W-20 full synthetic engine oil.
9. Start the engine and let it run for a few minutes. Check for any leaks around the drain plug and oil filter.
10. Turn off the engine, wait a few minutes, then check the oil level with the dipstick and adjust as necessary.
11. Reset the oil change indicator system according to your owner's manual.

Common Issues / Tips

• Oil Filter Location: The 3.6L Pentastar V6 engine in the Gladiator uses a traditional spin-on oil filter, which is generally easier to access than canister-style filters found on some other vehicles.
• Oil Consumption: Some 3.6L Pentastar engines have been known to consume a small amount of oil between changes. It's always a good practice to periodically check your oil level with the dipstick, especially if you drive under severe conditions.
• Crush Washer: Do not reuse the old crush washer. A new one ensures a leak-free seal. You can usually purchase these affordably at a dealership or auto parts store.
• Resetting the Oil Life Monitor: After any oil change, it's crucial to reset the oil life monitor so the vehicle accurately tracks the next service interval. Consult your owner's manual for specific instructions.
