Engine Oil Change: Jeep Wrangler 2012-2018

If you are reading this, then it may be time for an oil change. Oil changes are done to keep an engine from deteriorating. Over time, the engine may collect dirt and may even start corroding so it is a good idea to complete routine maintenance. Depending on how old your vehicle is, the oil that was used, and the driving conditions will vary on how frequent the oil should be changed. I typically would change my engine oil every 3,000 to 5,000 miles, but it is recommended to do so every 5,000 to 7,500 miles.

Changing your engine oil is a fairly simple task. Depending on where you live, you may be able to save some money doing it yourself. Now let’s get started!

What you will need:

  • Oil drain pan
  • 6 quarts of oil with desired grade (Mopar prefers 5W-20)
  • New oil filter (Specific for year 2012-2013 and 2014-2018)
  • Ratchet
  • 13mm and 24mm socket
  • Shop towels or paper towels
  • Gloves
  • Funnel
  • Torque wrench (up to 30 ft. lbs)

Step 1: Make sure you Jeep is on flat grounds and parking brakes engaged. Allow your engine to cool down if you have just driven it.

Step 2: Pop open the hood of your Jeep and remove the engine cover to expose the filter and oil fill cap. Remove the oil fill cap. Removing the cap allows the oil to drain easily when it comes time.



Step 3: Place the oil drain pan underneath the oil pan of the Jeep. Put some gloves and have your towels ready in case it s needed. The gloves will help protect you from hazardous chemicals and the towels will be used for cleaning. 

Step 4: Using the ratchet and 13mm socket, loosen the oil plug. Make sure your oil pan is positioned properly as the oil will flow out fairly quick. Remove the plug.


Step 5: While waiting for the oil to completely drain, you may proceed to remove the oil filter. Using the ratchet and 24mm socket, remove the cap and oil filter. Use some shop towels to catch and wipe off any oil that may drip into the engine as you are removing the filter.

Step 6: Separate the oil filter from the cap by gently pulling it straight out. Next, remove the o-ring on the filter cap. Install the new o-ring and push in the new oil filter. 


Step 7: Re-install the oil filter and cap. Tighten the cap until it is snug. Over tightening could damage the cap.

Step 8: Check if the oil is completely drained. Once it is drained completely, then install the plug. Torque the plug to 25 ft. lbs. Use a towel to wipe off any oil residue that may be left.

Step 9: Using the funnel, refill the engine with 6 quarts of oil and replace the cap. 


Step 10: Start the engine and let it run for a few minutes. Shut the Jeep off and give it a couple minutes to let the oil settle.

Step 11: Check and make sure the oil level is within limits. 

Step 12: Reset the oil indicator. To do this, you would need to put the Jeep in the “on” position without starting it. Then you need to depress the gas pedal three times within a 10 second time frame. Turn the Jeep off. Start it back off to make sure the indicator does not come back on or the oil life is 100%.

Note: After driving the Jeep a few times have a quick look to check if there are any leaks present. 

If you have any questions please do not hesitate to ask.



Hello! I was born and raised on a small island called Saipan for 18 years. Shortly after my high school graduation, I joined the United States Air Force. In 2016, I separated from the Air Force and moved to Denver, Colorado. In June 2017, I took a contracting job up here in Alaska. Since then, I have been living and experiencing the wonderful lifestyle of being up North!
