For the factory years verified in the OffroadMe source library, Jeep lists 6 US qt for the 3.6L Pentastar. The exact metric text is 5.7 L for 2013 and 5.6 L for 2014 and 2018. Those publications also specify SAE 5W-20 meeting MS-6395. The 2012 and 2015–2017 figures remain unverified here.
APPLIES TO: 2012–2018 Jeep Wrangler JK and JKU with the 3.6L Pentastar.
DOES NOT APPLY TO: 2007–2011 JK/JKU with the 3.8L engine or the 2018-and-newer Wrangler JL.
Safety Stop
Shut the engine off if the oil-pressure warning stays on, the dipstick shows no oil, or a fresh leak appears after service. Do not keep tightening a leaking filter cap or drain plug. Cross-threaded or damaged parts need inspection and repair, not more force.

Factory publications sometimes print 5.7 L and sometimes 5.6 L beside the same 6 US qt figure. Keep the metric value exactly as printed for the model year. Do not rewrite one year to match another.
Torque and Socket-Size Status
The previous version of this page displayed oil-filter-cap and drain-plug torque values plus socket sizes without an acceptable factory source in the project library. They have been removed as specifications.

| Oil drain-plug torque | [VERIFY: Jeep JK 3.6L oil drain-plug torque — confirm against exact-year factory service information] |
| Socket sizes | [VERIFY: oil-filter-cap and drain-plug tool sizes — confirm against the actual factory or replacement hardware] |
How to Use the Capacity Correctly
- Match the model year and engine. A 3.8L JK page or a Wrangler JL source is not evidence for the 3.6L JK.
- Use the exact factory wording. Do not change the printed metric figure because a calculator produces a different rounded value.
- Follow the service procedure. Confirm whether the listed amount applies to the service being performed, then verify the finished level as the factory procedure directs.
- Do not guess fastener torque. Obtain the exact-year factory service information before tightening the filter cap or drain plug.
Tools and Supplies
For a verified model year, use oil carrying the specified viscosity and material standard. Use a clean measuring container, the correct replacement filter for the exact application, and a torque wrench only after the fastener value is sourced. Check the installed cap and plug before choosing a socket; replacement hardware may differ.
What People Get Wrong
- Calling 5.6 L and 5.7 L a contradiction. They are different factory-published metric expressions beside a 6 US qt figure. Preserve the year-specific wording.
- Applying the 2013 figure to 2012. The project source library explicitly leaves 2012 unconfirmed.
- Publishing a torque value with a disclaimer. A warning does not make an unsourced number reliable.
- Mixing JK engines. The 2007–2011 3.8L and 2012–2018 3.6L need separate sources.

FAQ
How much oil does a Jeep JK 3.6L take?
The verified 2013, 2014 and 2018 factory publications list 6 US quarts. The metric wording varies: 2013 prints 5.7 L, while 2014 and 2018 print 5.6 L. OffroadMe has not yet verified every other model year.
What oil does the 3.6L Pentastar use in a Jeep JK?
The verified 2013, 2014 and 2018 sources specify SAE 5W-20 meeting Chrysler or FCA Material Standard MS-6395. Confirm the exact model year and the oil-filler-cap wording before service rather than assuming one publication covers the entire run.
Why do Jeep manuals show both 5.6 L and 5.7 L?
Factory publications use different metric rounding beside a 6 US qt figure. The correct editorial approach is to reproduce the value printed for that model year, not convert it again or force every year to use the same metric number.
What is the 3.6L oil-filter-cap torque?
OffroadMe does not currently have an acceptable factory source for that figure in its verified specification library. Treat the value as UNVERIFIED until it is confirmed against exact-year factory service information. Do not tighten a leaking or damaged cap harder.
What is the 3.6L oil drain-plug torque?
The drain-plug torque is not verified in the current project source library. Use factory service information for the exact model year and inspect the installed plug and threads. A number from another engine or an aftermarket plug should not be transferred by assumption.
Next Steps
- Jeep JK specification library — keep engine and model-year applications separated.
- Pentastar oil cooler housing guide — review the 3.6L housing topic separately from routine capacity.
- Jeep JK 3.8L oil capacity — use this only for 2007–2011 3.8L models.
TL;DR for Forum Posts
Verified factory data shows 6 US qt for the 2013, 2014 and 2018 JK 3.6L. The 2013 publication prints 5.7 L; 2014 and 2018 print 5.6 L, so keep the metric value tied to the year. This page does not treat 2012, 2015–2017, or the filter-cap and drain-plug torque figures as verified.
