Brands & Part Numbers
The new 3.6L V6 Pentastar engine does not use a traditional can style oil filter but rather, uses a disposable filter media that is installed into the top of the engine. This makes changing your oil super easy and without any additional mess. The following are 3 different brands along with their part numbers that you can buy including one from your dealership:
• Mopar #68079744A
• STP #S10955
• WIX #57144
As far as oil goes, you can use traditional dino oil in your engine but, you need to make sure that meets or exceeds MS-6395 standards.
Here’s a shot of everything you will need to change the oil in your 2012 Jeep JK Wrangler. As you can see, you will need 6 quarts of oil, a new filter media, some tools and a means to collect your used oil.

11. Install the new O-Ring onto your filter cap.
12. Install your new filter media onto the filter cap by pushing it in to it until it snaps in place.
13. Carefully reinstall your filter cap with new filter media attached back into the top of your engine.

16. Insert a funnel into the fill hole and pour in 6 quarts of oil.
17. Reinstall your engines oil fill cap.
18. Reinstall your engine cover by snapping it into place.
