2024 Jeep Wrangler Fluid Specs & Capacities

As an ASE-certified master technician, I’ve seen firsthand how using the correct fluids can make the difference between a Jeep that lasts for 200,000 miles and one that suffers from premature component failure. This guide details every essential fluid for your 2024 Jeep Wrangler (JL), ensuring you get the job done right.

Engine Oil

The heart of your Wrangler is its engine, and the correct oil is its lifeblood. For all gasoline engines available in the 2024 Wrangler (2.0L Turbo and 3.6L Pentastar V6), the required oil is SAE 0W-20.

• Specification: Look for an oil that is licensed to the API SP and ILSAC GF-6A standards. Critically, it must also meet the Stellantis (formerly Chrysler) material standard MS-6395. Using an oil without this specific approval can lead to warranty disputes and potential long-term engine wear. Most reputable full synthetic 0W-20 oils from major brands will list this specification on the bottle.
• Capacity: 5.0 quarts (4.7 liters). Always verify the level on the dipstick after filling.
• Interval: While the oil life monitoring system will alert you, a good rule of thumb is every 5,000-7,500 miles, or annually, especially if you frequently off-road or tow.

Engine Coolant (Antifreeze)

Jeep has used several different coolant types over the years, and mixing them is a recipe for disaster. Your 2024 Wrangler requires a specific Organic Acid Technology (OAT) coolant.

• Specification: Use Mopar Antifreeze/Coolant 10 Year/150,000 Mile Formula OAT which meets Chrysler specification MS-12106. This coolant is purple in color. Do NOT use older HOAT (Hybrid OAT) coolants (typically pink/orange) or any generic "universal" coolant. Mixing coolant chemistries can cause it to gel, leading to blockages, overheating, and costly damage to the radiator and heater core.
• Capacity: The system holds between 8.8 and 10.3 quarts (8.3-9.7 liters). For service, a 50/50 mix with distilled water is required. Never use tap water.
• Interval: As the name suggests, this is a long-life coolant. The initial factory fill is good for 10 years or 150,000 miles. When servicing, it’s wise to inspect the system every 30,000 miles.

Transmission Fluid

Transmission fluid is highly specific to the unit in your Jeep.

• 8-Speed Automatic (850RE): This transmission requires Mopar ZF 8&9 Speed ATF or an equivalent fluid meeting Stellantis spec MS-90030-A2. Do NOT use ATF+4 or any other type of ATF. Using the wrong fluid will cause severe shifting problems and internal damage.
  • Capacity: A drain and fill is typically around 5.8 quarts (5.5 liters), while a full system overhaul is closer to 9.0 quarts (8.5 liters).
• 6-Speed Manual (D478): This gearbox uses a specific lubricant, Mopar Manual Transmission Lubricant, meeting spec MS-9224.
  • Capacity: Approximately 1.6-1.7 quarts (1.5-1.6 liters).

Transfer Case Fluid

All 4WD Wranglers use a transfer case to send power to the front wheels. Despite the advanced off-road systems, the fluid required is a familiar one.

• Specification: Use Mopar ATF+4 or a licensed equivalent meeting MS-9602. While many other components have moved to more exotic fluids, the transfer case still relies on this trusty Chrysler spec.
• Capacity: Varies by transfer case model, from 1.1 to 2.1 quarts (1.0-2.0 liters). Fill until the fluid is level with the bottom of the fill plug hole.

Front & Rear Differential Fluid

Axle gear oil provides lubrication and protection for the differentials. The 2024 Wrangler uses a modern, synthetic fluid.

• Specification: Both front and rear axles call for SAE 75W-85 Synthetic Gear Lubricant meeting Stellantis specification MS-9020.
• Note on LSD: If your Wrangler is equipped with a Trac-Lok™ limited-slip differential (LSD), a small amount of Mopar Limited-Slip Additive must be added to the gear oil to prevent chatter during turns. Rubicon models with electronic locking differentials do not require this additive.
• Capacity:
  • Front: 1.1-1.3 quarts (1.0-1.2 liters)
  • Rear: 1.5-2.4 quarts (1.4-2.3 liters), depending on the specific axle (e.g., Dana 35, 44, etc.).

Brake & Clutch Fluid

Brake fluid is hygroscopic, meaning it absorbs moisture from the air, which can lead to a spongy pedal and corrosion. Regular flushes are critical.

• Specification: Use a high-quality DOT 3 brake fluid meeting MS-4574. While DOT 4 has a higher boiling point and is compatible, DOT 3 is the factory recommendation. Never use DOT 5 silicone fluid in a system not designed for it.
• Manual Clutch: The hydraulic clutch system on manual transmission models also uses this same DOT 3 brake fluid.
• Interval: Flush the brake system completely every 2-3 years, regardless of mileage.

Other Fluids

• Power Steering: The 2024 Jeep Wrangler uses an Electro-Hydraulic Power Steering (EHPS) system, which is a sealed unit. There is no fluid reservoir for the owner to check or top off.
• Windshield Washer Fluid: Use any quality all-season washer fluid, preferably with freeze protection down to -30°F (-34°C) to prevent frozen lines in winter.
