Fill to about 5.5 quarts, run the engine, then top up to the mark on the dipstick rather than pouring the full amount in at once. ### What kind of oil does a 2012-2017 Jeep Wrangler take? 0W-20 meeting Chrysler MS-6395 / API SN, full synthetic (required, not merely recommended). ### Can you use a different viscosity in a 2012-2017 Jeep Wrangler? The manufacturer also permits 5W-20 (Acceptable substitute per some Mopar documentation if 0W-20 is unavailable). Anything outside that list is a decision you are making against the factory specification. ### How often does a 2012-2017 Jeep Wrangler need an oil change? Oil-life monitor determines interval, typically ~10,000 mi with full synthetic (normal); 5,000 mi (severe service, off-road, towing, frequent short trips). Short trips, towing, extended idling, and dusty or very cold conditions all put the vehicle on the severe-service side of that interval. ### What oil filter does a 2012-2017 Jeep Wrangler take? The OEM filter is Mopar MO-339 (spin-on, early production) or Mopar 68191349AC (cartridge, later production), the Pentastar switched filter styles mid-run; confirm against the block before ordering. Common equivalents: Fram XG10060 (Ultra, spin-on), Wix 51334, Purolator L14459 (cartridge equivalent). ## Sources - [Mopar/AMSOIL OE lookup, 2013 Jeep Wrangler 3.6L oil spec](https://www.amsoil.com/lookup/auto-and-light-truck/2013/jeep/wrangler/3-6l-6-cyl-engine-code-g-erb-h/) - [WranglerForum, 3.6L oil capacity (owner's manual quotes, 6 qt)](https://www.wranglerforum.com/answers/how-many-quarts-of-oil-does-a-jeep-wrangler-3-6-take/) - [WranglerForum, Mopar 3.6L oil filter part numbers (spin-on vs. cartridge)](https://www.wranglerforum.com/threads/mopar-3-6l-oil-filters-difference.1640369/) - [ChallengerTalk, Pentastar 3.6L spark plug part number/gap (Champion RER8ZWYCB4 / Mopar SP149125AD)](https://www.challengertalk.com/threads/spark-plug-replacement-for-3-6l-pentastar.213266/) - [WranglerForum, Rubicon Dana 44 rear diff fluid (75W-140 Mopar synthetic)](https://www.wranglerforum.com/threads/diff-oil-gear-oil-for-rubicon-dana-44-rear.2413691/) - [WranglerForum, JK oil-change light reset procedure (accelerator-pedal method)](https://www.wranglerforum.com/threads/oil-change-notification-reset.147085/) - [au7o.io, 3.6L Pentastar oil cooler/filter housing cracking (2012-2025)](https://au7o.io/known-issues/jeep-wrangler) - [Edmunds, 2012 Jeep Wrangler specs (fuel tank, curb weight)](https://www.edmunds.com/jeep/wrangler/2012/features-specs/) - [Car and Driver, 2012 Jeep Wrangler Sport 4WD 2dr specs/EPA mpg](https://www.caranddriver.com/jeep/wrangler/specs/2012/jeep_wrangler_jeep-wrangler-2-door_2012) - [ExtremeTerrain, Jeep Wrangler JK factory tire sizes by trim](https://www.extremeterrain.com/jeep-wrangler-tire-size-guide.html) ## Other Jeep Wrangler generations - [2018-2025 Jeep Wrangler oil](https://whichcarparts.com/cars/jeep/wrangler/2018-2025/oil) Or [compare all generations](https://whichcarparts.com/cars/jeep/wrangler/oil). ## More for the 2012-2017 Jeep Wrangler - [Battery](https://whichcarparts.com/cars/jeep/wrangler/2012-2017/battery) - [Tires & wheels](https://whichcarparts.com/cars/jeep/wrangler/2012-2017/tires) - [Wiper blades](https://whichcarparts.com/cars/jeep/wrangler/2012-2017/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/jeep/wrangler/2012-2017/filters) - [Bulbs](https://whichcarparts.com/cars/jeep/wrangler/2012-2017/bulbs) - [Brakes](https://whichcarparts.com/cars/jeep/wrangler/2012-2017/brakes) - [Fluids](https://whichcarparts.com/cars/jeep/wrangler/2012-2017/fluids) - [Service schedule](https://whichcarparts.com/cars/jeep/wrangler/2012-2017/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/jeep/wrangler/2012-2017/common-problems) - [Oil light reset](https://whichcarparts.com/cars/jeep/wrangler/2012-2017/oil-reset) - [Key fob battery](https://whichcarparts.com/cars/jeep/wrangler/2012-2017/key-fob-battery) - [Specs](https://whichcarparts.com/cars/jeep/wrangler/2012-2017/specs) Specifications vary with engine option, production date, and market.
