2019 Jeep Wrangler Oil Capacity & Filter Guide

The 2019 Jeep Wrangler takes exactly 5.0 quarts (4.7 liters) of engine oil when performing an oil and filter change, regardless of whether your vehicle is equipped with the 2.0L Turbo or the 3.6L Pentastar V6 engine. Maintaining the correct oil level and using the right specifications is critical for keeping your JL-generation Wrangler trail-ready and reliable for years to come.

Quick answer

• Oil Capacity: 5.0 quarts (4.7 Liters) with filter change.
• Recommended Weight: 0W-20 (for 3.6L V6) or 5W-30 (for 2.0L Turbo).
• Oil Specification: Chrysler MS-6395 (API SN Plus or API SP certified).
• Oil Filter (3.6L V6): Mopar MO-349 (OEM). Aftermarket: Fram CH11665, Wix WL10010.
• Oil Filter (2.0L Turbo): Mopar MO-339 (OEM). Aftermarket: Fram CH12282, Wix WL10376.

Capacity by engine option

For the 2019 model year (JL generation), Jeep offered two engine choices. While the capacity remains the same, the required oil viscosity differs between the two powerplants.

Oil change interval

Your 2019 Jeep Wrangler is equipped with an Automatic Oil Change Indicator System that adjusts intervals based on engine operating conditions. However, here are the baseline rules:

• Normal Duty: Replace oil and filter every 7,500 to 10,000 miles, or every 12 months, whichever comes first. Do not exceed 10,000 miles or one year under any circumstances.
• Severe Duty: Replace oil and filter every 4,000 to 5,000 miles. Severe duty applies if you frequently drive off-road, in dusty environments, idle extensively, tow heavily, or drive primarily in extreme heat or cold.

Drain plug torque

• Torque Spec: 20 ft-lbs (27 Nm).
• Note: The 2019 Wrangler uses a drain plug with an integrated rubber seal. Inspect the seal at every oil change. If the rubber is torn, flattened, or deteriorating, replace the entire drain plug. Do not over-tighten, as the oil pan threads can be stripped.

How to change the oil

Both the 2.0L and 3.6L engines utilize a top-mounted cartridge-style oil filter, making the oil change process highly accessible.

1. Warm the engine: Run the Jeep for a few minutes to warm the oil, allowing it to drain faster and suspend any contaminants.
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 and remove the cap. Pull the old paper cartridge filter out.
3. Drain the oil: Place a drain pan under the engine oil pan. Remove the 13mm drain plug and allow the oil to drain completely.
4. Reinstall drain plug: Once drained, reinstall the drain plug and torque to 20 ft-lbs.
5. Install the new filter: Snap the new cartridge filter into the filter cap. Replace the rubber O-ring on the cap with the new one provided in the filter box, and lightly lubricate the O-ring with fresh oil. Thread the cap back into the housing and torque to 18 ft-lbs (25 Nm). Do not over-tighten!
6. Refill: Add exactly 5.0 quarts of the specified engine oil.
7. Check and reset: Start the engine, check for leaks, and turn it off. Wait a few minutes, check the dipstick, and then reset the oil life monitor on your dashboard.

Common issues / tips

• Oil Filter Housing Cracks (3.6L V6): The Pentastar V6 is notorious for cracked plastic oil filter housings. This usually happens when the filter cap is over-tightened. Always use a torque wrench (set to 18 ft-lbs) on the cap. If you notice oil pooling in the engine valley, the housing likely needs replacement.
• O-Ring Placement: When replacing the O-ring on the filter cap, ensure it sits in the correct groove, not pushed all the way to the top lip. An improperly placed O-ring will cause a massive oil leak upon startup.
• ESS System: Because the 2019 Wrangler utilizes Engine Stop/Start (ESS) technology, high-quality, fully synthetic oil meeting the MS-6395 specification is highly recommended to protect bearings during frequent starts.
