2024 Jeep Gladiator Oil Capacity & Filter Guide

The 2024 Jeep Gladiator requires 5.0 quarts (4.7 liters) of 0W-20 motor oil when replacing the oil and filter on its standard 3.6L Pentastar V6 engine. Maintaining the correct oil level and using the right specifications is critical to keeping your Jeep’s engine running smoothly whether you are commuting on the highway or crawling on the trails. Below is your comprehensive guide to the oil capacity, filter part numbers, and service specifications for the 2024 Jeep Gladiator.

Quick Answer: Oil Specs & Filter Part Numbers

For a standard oil change on the 2024 Jeep Gladiator (3.6L V6), here is everything you need to know:

• Oil Capacity: 5.0 quarts (4.7 Liters) with filter change.
• Recommended Oil Weight: SAE 0W-20.
• Oil Specification: API SP / ILSAC GF-6A, Chrysler Material Standard MS-6395.
• OEM Oil Filter: Mopar MO-349 (Part number 68191349AC).
• Aftermarket Filters: Fram CH11665, WIX WL10010, Mobil 1 M1C-254A.

Capacity by Engine Option

For the 2024 model year, Jeep discontinued the 3.0L EcoDiesel option for the Gladiator. The only available engine is the venerable 3.6L Pentastar V6.

Oil Change Interval

Modern synthetic oils and the Gladiator's Oil Life Monitor make tracking your maintenance easy, but you should base your intervals on how you use the truck:

• Normal Duty: Up to 10,000 miles or 12 months, whichever comes first. Rely on the dashboard Oil Life Monitor.
• Severe Duty: Every 4,000 to 5,000 miles or 6 months. Severe duty includes off-roading, towing, extensive idling, frequent short trips, or driving in dusty/sandy conditions. Given the Gladiator's purpose, many owners fall into the severe duty category.

Drain Plug Torque

• Torque Spec: 20 ft-lbs (27 Nm).
• Crush Washer: The 3.6L engine’s drain plug features an integrated rubber O-ring seal rather than a traditional crush washer. Inspect this O-ring at every oil change; if it is flattened, cracked, or leaking, replace the entire drain plug.

How to Change the Oil

The 3.6L Pentastar V6 uses a top-mounted cartridge-style oil filter, making it one of the easiest engines to service.

1. Warm up the engine: Run the engine for a few minutes to warm the oil, which helps it drain faster and suspend contaminants. Shut off the vehicle and apply the parking brake.
2. Remove the filter cap: Open the hood and locate the oil filter housing cap on the top of the engine. Use a 24mm socket to loosen the cap. Letting air into the top allows the oil trapped in the housing to drain down into the pan.
3. Drain the oil: Position your drain pan under the oil pan drain plug (13mm socket). Remove the plug and let the oil drain completely.
4. Reinstall drain plug: Wipe the sealing surface clean, inspect the drain plug O-ring, and reinstall the plug. Torque to 20 ft-lbs.
5. Replace the filter cartridge: Pull the old filter element out of the plastic cap. Remove the old O-ring on the cap using a pick. Lube the new O-ring with fresh oil, install it into the proper groove on the cap, and snap the new filter cartridge into the cap.
6. Install the filter: Thread the cap and new filter back into the housing by hand. Torque the cap to 18 ft-lbs (25 Nm). Do not overtighten, or the plastic cap will crack.
7. Refill and verify: Add exactly 5.0 quarts of 0W-20 oil. Start the engine, check for leaks under the vehicle and at the filter cap, then shut it off. Let it sit for 5 minutes and verify the fluid level on the dipstick.
8. Reset the Oil Life Monitor: Turn the ignition to the "ON/RUN" position (without starting the engine). Navigate to the Vehicle Info menu on the dash display, go to the Oil Life screen, and hold the "OK" button to reset it to 100%.

Common Issues / Tips

• Top-Mounted Filter Housing Failure: The 3.6L Pentastar is notorious for oil cooler/filter housing assemblies that crack and leak oil down into the valley of the engine. Overtightening the plastic oil filter cap is a leading cause of this premature failure. Always use a torque wrench on the 24mm cap, or simply tighten it until it is snugly seated.
• O-Ring Placement: When replacing the O-ring on the filter cap, ensure it goes into the designated groove and is not pushed all the way up against the flange. Incorrect placement will cause a massive oil leak upon startup.
• Check the Dipstick: Always double-check your oil level on a level surface. Even though the capacity is 5.0 quarts, variances in draining can leave a few ounces behind.
