2025 Jeep Grand Cherokee Fluid Specifications: Complete OEM Guide

As an ASE-certified master technician, I cannot stress enough how critical it is to use the exact factory-specified fluids in modern vehicles. The 2025 Jeep Grand Cherokee (WL generation) is a technological marvel, featuring complex powertrains like the 3.6L Pentastar V6 and the advanced 2.0L Turbo 4xe Plug-in Hybrid. Gone are the days when you could grab a universal jug of oil or transmission fluid off the shelf. Using the wrong chemistry in these highly engineered systems can lead to catastrophic failures, voided warranties, and massive repair bills.

Below is your definitive fluid specification guide for the 2025 Jeep Grand Cherokee, complete with Mopar specification numbers and capacities. Always verify your specific sub-model and towing package details in your owner’s manual or OEM service information.

Engine Oil

For the 3.6L Pentastar V6, the factory specifies 0W-20 engine oil meeting API SP/ILSAC GF-6A and Mopar MS-6395 standards. The thin 0W-20 viscosity is crucial for operating the Variable Valve Timing (VVT) solenoids properly. Using a thicker oil will trigger check engine lights and cause timing issues.

If you are servicing the 2.0L Turbo 4xe PHEV, you must use 5W-30 engine oil that meets Mopar MS-13340 and API SP. Because the 4xe engine frequently cycles on and off, it requires an oil specifically formulated to handle fuel dilution and sudden high-load demands. Interval Note: The oil life monitor will dictate your interval, but as a master tech, I recommend never exceeding 7,500 miles or 12 months, especially on the turbo models.

Engine Coolant

Jeep uses Mopar Antifreeze/Coolant 10 Year/150,000 Mile Formula OAT (Organic Additive Technology), which meets spec MS-90032. This fluid is distinctly purple (though it can sometimes look pinkish depending on the light). Pitfall Warning: Never mix OAT coolant with HOAT (Hybrid Organic Additive Technology) or traditional green IAT coolants. Mixing these will cause the corrosion inhibitors to drop out of suspension, turning the coolant into a sludgy gel that will clog your heater core and radiator. If you must top it off, use only distilled water or the exact MS-90032 spec.

Transmission Fluid

The 2025 Grand Cherokee utilizes the robust ZF 8-speed automatic transmission. It strictly requires Mopar ZF 8 & 9 Speed ATF. Do not use ATF+4, Dexron VI, Mercon LV, or any "universal" multi-vehicle ATF. The ZF transmission has highly specific frictional requirements for its clutch packs. Interval Note: Stellantis considers this a "fill for life" fluid under normal driving conditions. However, if you regularly tow heavy loads or drive in severe off-road conditions, I highly recommend performing a pan/filter replacement and fluid drain-and-fill around 60,000 to 80,000 miles.

Transfer Case

Depending on whether you have the Quadra-Trac I, Quadra-Trac II, or Quadra-Drive II 4WD system, your transfer case fluid requirements will dictate Mopar ATF+4 (Spec MS-9602). It is a common mistake to put gear oil into these modern active transfer cases—doing so will instantly destroy the internal chain and clutch assemblies. Change this fluid every 60,000 miles (or 30,000 miles under severe off-road/towing use).

Front and Rear Differentials

Both the front and rear differentials call for 75W-85 GL-5 Synthetic Gear Lubricant. Crucial Note for Rear Differentials: If your Grand Cherokee is equipped with the Electronic Limited Slip Differential (ELSD) found in the Quadra-Drive II system, you must add a Mopar Limited Slip Additive (Friction Modifier). Failing to include this additive will cause severe chatter and grinding from the rear end during tight turns, eventually destroying the clutch packs. Standard open differentials do not require this additive.

Brake Fluid

The factory specification is DOT 3 brake fluid meeting Mopar MS-4574. Do not substitute DOT 5 (silicone-based) fluid, as it is incompatible with the ABS hydraulic control unit and will cause seal failure. While DOT 4 can technically be mixed with DOT 3, it is best to stick strictly to the DOT 3 spec to ensure optimal ABS and electronic stability control performance. Brake fluid is hygroscopic (it absorbs moisture), so flush the system every 2 to 3 years regardless of mileage.

Power Steering

The 2025 Jeep Grand Cherokee utilizes Electric Power Steering (EPS). There is no hydraulic power steering pump, no hoses, and no fluid to check or replace.

Washer Fluid and DEF

Use any high-quality windshield washer fluid rated for your local climate. Ensure it has adequate freeze protection if you live in a cold region. As for Diesel Exhaust Fluid (DEF), Jeep does not offer a diesel engine for the 2025 Grand Cherokee, so there is no DEF system to maintain.

Maintaining your 2025 Jeep Grand Cherokee with these exact factory specifications will ensure it delivers the reliability and capability you expect. When you need professional service, don't trust your complex vehicle to just anyone. Find a trusted shop on Repairius.
