2025 Jeep Gladiator Oil Capacity & Filter Guide

The 2025 Jeep Gladiator equipped with the standard 3.6L Pentastar V6 engine takes exactly 5.0 quarts (4.7 liters) of 0W-20 engine oil when performing a standard oil change with a filter replacement. As an ASE-certified master technician, I regularly service these versatile trucks, and having the right fluids and torque specs on hand is crucial to keeping the legendary Pentastar running smoothly.

Below is your comprehensive reference guide for servicing the oil on your 2025 Jeep Gladiator.

Capacity by engine option

For the 2025 model year, Jeep has streamlined the Gladiator lineup, making the proven 3.6L Pentastar V6 the sole powertrain offering.

Oil change interval

Jeep equips the 2025 Gladiator with an automatic Oil Life Indicator system that alerts you when service is due based on operating conditions. However, you should adhere to these baseline intervals:

• Normal Duty: Up to 10,000 miles or 12 months, whichever comes first (or when the Oil Life Indicator turns on).
• Severe Duty: 4,000 to 5,000 miles or 6 months. Severe duty includes extensive off-roading, towing, idling, or driving in dusty/sandy environments.

Drain plug torque

• Torque Spec: 20 ft-lbs (27 Nm).
• Crush Washer Note: The factory drain plug on the 3.6L V6 often features an integrated rubber gasket. Inspect this O-ring style seal every time you remove the plug. If the rubber is flattened, torn, or missing, replace the drain plug or the seal immediately to prevent leaks. Do not overtighten, as stripping the aluminum oil pan is a costly mistake.

How to change the oil

1. Prepare the vehicle: Park on a level surface, set the parking brake, and run the engine for a few minutes to warm the oil slightly, allowing it to drain faster.
2. Loosen the filter cap: Using a 24mm socket, loosen the plastic oil filter housing cap located under the hood on the top-top center of the engine. Do not fully remove it yet; breaking the seal allows the oil in the housing to drain down into the pan.
3. Drain the oil: Position your catch pan underneath the engine and remove the 13mm drain plug. Allow all the oil to drain completely.
4. Reinstall the drain plug: Clean the plug, inspect the seal, and torque it to 20 ft-lbs (27 Nm).
5. Replace the filter: Remove the plastic filter cap assembly. Pull the old paper cartridge filter out and snap the new one into place. Remove the old rubber O-ring on the cap with a pick, lubricate the new O-ring with fresh engine oil, and install it in the exact same groove. Torque the plastic cap to 18 ft-lbs (25 Nm).
6. Refill the engine: Pour exactly 5.0 quarts of high-quality 0W-20 oil into the oil filler neck.
7. Verify and reset: Start the engine and check for leaks. Turn it off, wait five minutes, and verify the oil level on the dipstick. Finally, reset the Oil Life system via the dashboard instrument cluster menus.

Common issues / tips

The most frequent issue technicians see with the 3.6L Pentastar V6 across all Jeep models is a cracked or leaking oil filter housing assembly. This is almost always caused by overtightening the plastic oil filter cap. Always use a torque wrench set to 18 ft-lbs (or "snug") and resist the urge to crank down on the 24mm nut. Furthermore, failure to lubricate the new O-ring on the filter cap can cause it to bunch up and leak severely, or make it impossible to remove during the next service.
