Jeep Grand Cherokee 3.6 Oil Capacity: WK2 vs. WL
Grand Cherokee 3.6L Pentastar oil-capacity chart with filter-included values, generation breaks, refill procedure, dipstick checks, FAQs, cautions.
The 2011–2021 WK2 Grand Cherokee 3.6L uses 6.0 US qt (5.7 L) with filter; the 2022-and-newer WL 3.6L manual lists 5.0 US qt (4.7 L).
The 2011–2021 WK2 Grand Cherokee 3.6L uses 6.0 US qt (5.7 L) with filter; the 2022-and-newer WL 3.6L manual lists 5.0 US qt (4.7 L). That published capacity is a service starting point, not permission to empty the last fraction of a bottle into the crankcase. Drain time, oil temperature, cooler volume, filter construction, vehicle angle, and residual oil all affect the amount required to reach the dipstick's full mark.
WK2 and WL are separate vehicle/engine service applications. The generation code, not the 3.6L deck-lid description, selects the six-quart or five-quart row. This guide separates the generations in the table, keeps filter-included and filter-excluded figures distinct, and explains a repeatable refill check. The 2021 calendar/model-year transition can be confusing, and performance engines use different rows. Never average the two capacities.
Refill below the listed total first, start the engine long enough to fill the filter, inspect for leaks, shut it down, wait on level ground, and finish by dipstick. That process protects against both an underfilled engine and the aeration, leakage, or catalyst trouble that overfilling can cause.

Jeep Grand Cherokee 3.6 Oil Capacity
| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| 2011–2021 WK2 3.6L | 6.0 US qt | 5.7 L with filter |
| 2022+ WL 3.6L | 5.0 US qt | 4.7 L with filter |
| WL oil specification | SAE 0W-20 full synthetic | MS-6395; API trademark required |
| Platform check | WK2 vs. WL / Grand Cherokee L | Confirm VIN and manual cover |
The WL platform reduced the published service quantity by a full quart even though both generations carry a 3.6L badge. The cited WL manual also specifies SAE 0W-20 full synthetic meeting MS-6395.
The generation break that matters for Grand Cherokee 3.6L Pentastar
WK2 and WL are separate vehicle/engine service applications. The generation code, not the 3.6L deck-lid description, selects the six-quart or five-quart row. Read the model-year and engine row together; a badge, displacement, or oil cap by itself may span more than one internal engine revision. The values below are drain-and-refill quantities with the filter unless the row says otherwise.
The 2021 calendar/model-year transition can be confusing, and performance engines use different rows. Never average the two capacities. Use the oil grade and manufacturer approval from the same model-year manual as the capacity. Capacity, viscosity, and approval are three separate specifications.
Oil-capacity chart for Grand Cherokee 3.6L Pentastar
Use the chart as an application lookup. WK2 and WL are separate vehicle/engine service applications. The generation code, not the 3.6L deck-lid description, selects the six-quart or five-quart row. A capacity printed beside the wrong engine code is not “close enough”; even engines sharing the same displacement can have different pans, filters, coolers, or drain-back behavior. If the vehicle has been swapped, rebuilt, or fitted with an aftermarket pan, use the installed hardware manufacturer's capacity and calibration marks.
The most common current application begins near 6.0 US qt. Begin below that amount and finish by measurement. The difference between the add and full marks is often about one quart, but do not assume that relationship when the dipstick is aftermarket, damaged, or paired with a non-original tube. Investigate a reading that remains absent or implausibly high.

Common causes of a capacity mismatch
The WL platform reduced the published service quantity by a full quart even though both generations carry a 3.6L badge. The cited WL manual also specifies SAE 0W-20 full synthetic meeting MS-6395. If the verified dipstick result and the expected quantity disagree materially, stop and identify the cause instead of choosing whichever number is more convenient.
- The lookup used the model name but not the model year or engine code.
- The quoted figure excluded the filter while the filter was replaced.
- The vehicle was not level or the oil had not drained back before checking.
- An oil cooler, remote filter, aftermarket pan, engine swap, or incorrect dipstick changed the system.
- The old filter gasket remained on the housing or a leak began after startup.
- The crankcase was filled to the advertised capacity without a final dipstick check.
Jeep Grand Cherokee 3.6L Pentastar specifications can change by model year, engine, platform, wheel, and installed component. Confirm the VIN or engine identity, part numbers, fastener condition, and the current manufacturer instructions before service.

How much oil does the Grand Cherokee 3.6L Pentastar take?+
The 2011–2021 WK2 Grand Cherokee 3.6L uses 6.0 US qt (5.7 L) with filter; the 2022-and-newer WL 3.6L manual lists 5.0 US qt (4.7 L). Confirm the year/engine row and finish by the dipstick rather than treating the capacity as an exact pour-in amount.
