Jeep Wrangler Pentastar 3.6L Oil Change
The jeepfan.com 2012 Wrangler Rubicon hit 3588 miles and the Change Oil indicator started showing on the instrument cluster after every startup. Time for the first oil change..
The 3.6L Pentastar V6 uses a drop in style filter that makes installing a new filter a snap and can be changed without even laying under the Jeep.
Items Required
- 24mm and 13mm sockets and ratchet
- 6 quarts 5W30 Motor Oil
- Oil Filter – We used a Fram CH10955
- Drain Oil Container
- Funnel
- Rags
Procedure
Pull up on the front edge of the top engine cover. After pulling up you can pull the cover off the engine by pulling it forward. There are hinges on the rear of the cover that hold it in place.

After the cover is removed locate the oil filter cap and using a 24mm socket remove the cap. The filter will remain attached to the cap. Pull gently on the filter and it will pop out of the cap. Install the new filter and o-ring.

Tighten up the cap and move to the underside of the Jeep. Using a 13mm socket loosen and remove the oil drain plug. Make sure you have a drain oil container ready to catch the oil. After allowing the oil to drain completely reinstall the plug and tighten.

After filling the engine start it and allow it to run a few minutes. Observe the oil pressure gauge and make sure it is not lit. Shut off the engine and give it a minute for all the oil to drain to the bottom of the engine. Check the oil level and clean up.
Resetting the change oil indicator
With the engine off turn the key to the run position but do not start the engine. Depress the gas pedal all the way to the floor 3 times within the first 10 seconds of turning on the key. The change oil indicator should not return until the next interval.
Final
Check the oil periodically to ensure the engine has the proper amount of oil.
Note
Some people believe they should change the oil on their new Jeep earlier than the scheduled interval. It is said that Chrysler puts additives in the original oil to aid in engine break in and that the oil should not be changed early.
