2022 Jeep Grand Cherokee — Fluid Type Specs

As an ASE-certified master technician, I’ve serviced countless Jeep Grand Cherokees. The 2022 model year marked the full transition to the new WL generation (which debuted in 2021 as the Grand Cherokee L). With this complete redesign and the introduction of the 4xe plug-in hybrid alongside the trusty 3.6L Pentastar V6 and 5.7L Hemi V8, getting your fluid specifications exactly right is more critical than ever. Modern Stellantis (FCA) drivetrains are highly sensitive to incorrect fluid viscosities, friction modifiers, and additive packages.

Below is your definitive, factory-spec fluid guide for the 2022 Jeep Grand Cherokee (WL generation).

Note: Capacities are approximate. Always verify proper levels using factory dipsticks, sight holes, or overflow procedures.

Engine Oil

For the 2022 Grand Cherokee, oil specification varies drastically based on the engine under your hood.

• 3.6L Pentastar V6: Requires 0W-20 full synthetic meeting API SP and Chrysler MS-6395.
• 5.7L Hemi V8: Requires 5W-20 full synthetic meeting API SP and Chrysler MS-6395. (Using thicker oil in the Hemi can cause issues with the Multi-Displacement System / cylinder deactivation).
• 2.0L Turbo 4xe (PHEV): Requires 5W-30 full synthetic meeting Mopar MS-13340. The turbocharged direct-injection engine is highly susceptible to Low-Speed Pre-Ignition (LSPI), so the API SP standard is strictly required.

Intervals & Pitfalls: Follow the Oil Life Monitor on the dash, but as a master tech, I recommend never exceeding 7,500 miles or 12 months between changes, especially on the 5.7L Hemi to protect the lifters and camshaft.

Engine Coolant

The 2022 Grand Cherokee utilizes Mopar 10-Year/150,000 Mile Formula OAT (Organic Additive Technology) coolant, which meets Stellantis spec MS-90032. This fluid is distinctly purple.

Intervals & Pitfalls: Do NOT mix OAT (Purple) with the older HOAT (Hybrid Organic Additive Technology - Orange/Pink) fluid used in pre-2013 Jeeps, or any "universal" green coolant. Mixing these coolants will cause the chemical packages to react, forming a thick sludge that will quickly clog your heater core and radiator. If you are topping off, use only 50/50 premixed OAT coolant meeting MS-90032.

Transmission Fluid

All 2022 Grand Cherokees use a version of the ZF 8-speed automatic transmission (specifically the 850RE or ZF 8HP75). This transmission requires Mopar ZF 8 & 9 Speed ATF meeting MS-11215.

Intervals & Pitfalls: Jeep considers this a "fill for life" fluid under normal driving conditions. However, if you regularly tow, drive off-road, or operate in severe conditions, professional technicians recommend a fluid and pan/filter replacement every 60,000 to 80,000 miles. Never use universal ATF, Dexron VI, or Mercon LV in this transmission. The ZF unit is incredibly sensitive to fluid viscosity and friction modifiers; using the wrong fluid will result in harsh shifting and premature clutch wear.

Transfer Case and Differentials

Four-wheel drive 2022 Grand Cherokees are equipped with advanced 4x4 systems (Quadra-Trac I, Quadra-Trac II, or Quadra-Drive II).

• Transfer Case: Usually specifies Mopar ATF+4 (MS-9602), but certain active transfer cases specify a dedicated BorgWarner transfer case fluid. Always verify your specific transfer case RPO code in the OEM service info before filling.
• Differentials: Both the front and rear require 75W-85 GL-5 synthetic gear lubricant (MS-9020).
• eLSD Note: If your Grand Cherokee is equipped with Quadra-Drive II (which includes an Electronic Limited Slip Differential in the rear), you must add Mopar Limited Slip Additive (Friction Modifier) to the rear differential to prevent clutch chatter during tight turns.

Intervals: Differential and transfer case fluids should be inspected every 30,000 miles and changed every 40,000 to 60,000 miles, or more frequently if submerged in water during off-road excursions.

Brake Fluid

The braking system requires DOT 3 brake fluid meeting MS-4395.

Intervals & Pitfalls: Brake fluid is hygroscopic, meaning it absorbs moisture from the air over time. This lowers the boiling point of the fluid and can corrode ABS module internals. Flush the brake fluid every 2 to 3 years regardless of mileage. While DOT 4 is backward compatible with DOT 3 and offers a higher boiling point, always stick to the manufacturer's recommendation unless operating under heavy towing conditions where DOT 4's high boiling point is required—just remember DOT 4 absorbs moisture faster than DOT 3. Never use DOT 5 (silicone-based) fluid, as it will destroy the ABS system seals.

Power Steering & Washer Fluid

• Power Steering: The 2022 Jeep Grand Cherokee features Electric Power Steering (EPS). There is no power steering pump, no lines, and no fluid to check or change.
• Washer Fluid: Use any standard high-quality washer fluid. For colder climates, ensure it is rated for sub-zero temperatures (e.g., -20°F or lower) to prevent the fluid reservoir and pump from freezing and cracking.

Maintaining your 2022 Jeep Grand Cherokee with the correct factory-specified fluids is the single best way to ensure it lasts for hundreds of thousands of miles. Remember, when in doubt, always refer to your owner's manual or factory service data for your specific VIN.
