Oil Change Procedure for 2020 Jeep Wrangler 3.0L EcoDiesel with Mopar 68507598 AA

The all-new ECOGARD S11880 synthetic cartridge oil filter is a direct replacement for the unique new Mopar 68507598AA oil filter, which we introduced with an in-depth overview last month. This new filter is used to service the 3rd generation 3.0L EcoDiesel engines found in the 2020-2021 Jeep Wrangler, Jeep Gladiator and 2019+ Ram 1500. In the introduction last month, we highlighted the filter’s strange composition and unusual components, such as a new filter cap with every oil change and pre-installed O-rings. With all the weird features of the Mopar 68507598 AA compounded by a higher-than-average cost and a required 8.5 quarts of European spec synthetic oil, a lot of people are wondering what the actual oil change and filter installation is going to be like. Well, today we’ve got you covered. Here’s our process breakdown for an oil change on the 2020 Jeep Wrangler with 3rd generation 3.0L EcoDiesel.

Parts/Fluid Needed:

Oil Filter: Mopar 68507598 AA or ECOGARD S11880
Oil: 9 quarts or 8.5 liters 5W-40 Synthetic Oil – API SN MS 12991 is the recommended Fiat Chrysler oil specification

For additional technical specifications, see the 2020 Jeep Wrangler Diesel Supplement Manual.

Tools Needed:

  • Ratchet
  • 27mm (6 sided, not 12 point) or 1 1/16” oil filter socket. Note: A spanner wrench will suffice but will be more challenging
  • 13mm (6 sided, not 12 point) or 1/2” socket
  • Large bucket or oil storage container (10 quart or larger)
  • Funnel
  • Clean rags

2020 Jeep Wrangler 3.0L EcoDiesel Oil Change Process with Mopar 68507598 AA

Step 1: If the Jeep is cold, start and run it for 2-3 minutes. This will bring the oil temp to about 100 degrees F, which will allow it to flow better without burning your hands when draining.  If the vehicle has been running at normal operating temperature, give it 10-15 minutes to cool down so that the oil doesn’t burn your hands when removing the drain plug.

Step 2: Pop the hood and remove the oil fill cap. Also pull the dipstick out past the O-ring for better flow when the oil pan drain plug is removed.

Step 3: Get under the Jeep with a large bucket. Position the bucket directly underneath the oil pan drain plug. Unlike the Ram 1500, the drain plug on the Wrangler is completely unobstructed so drainage should be a less messy task.


Step 4: Remove the oil pan drain plug using a 13mm or 1/2 in. socket

Step 5: Using the 27mm oil filter cap socket, remove the oil filter housing cap.

Note: The oil filter housing is located underneath the air intake pipe. While it is possible to get a ratchet or spanner wrench underneath the pipe, we recommend removing the engine cover and air intake pipe for easier access and less mess when removing the filter and cap from the housing.

Step 6: Prepare the new oil filter and cap assembly for installation. First, remove the new filter from the box and inspect to make sure the O-rings are installed in the correct places. If all O-rings are properly in place, lubricate them with a small amount of clean oil. The application of clean oil helps to ensure that the O-rings don’t pinch or bind when tightening the cap.

Step 7: Install the cap and filter assembly into the oil filter housing. Start by hand tightening the cap and then finish tightening with the 27mm or 1 1/16” socket and torque wrench set to recommended 25Nm as shown on the oil filter housing cap.

Note: If you chose to remove the engine cover and air intake pipe for easier access to the filter, make sure to re-install after you’ve installed the new filter and cap.

Step 8: Get back under the Jeep with the 13mm or 1/2” socket and ratchet. By this time, the oil should have completely drained. Reinstall the oil pan drain plug by hand until it sits snug on the rubber sealing surface of the drain pan. Finish tightening with 1 or 2 turns of the ratchet – taking care not to over-tighten.

Step 9: Place a funnel into the oil fill hole on the valve cover and add 9 quarts or 8.5 liters of fresh 5w-40 API SN MS 12991 synthetic oil.

Step 10: Start the Jeep and run it for a short time while inspecting the oil filter cap and oil pan drain plug for any leaks under pressure.

Step 11: Reset oil life monitor per instructions found in the owner’s manual.

As you can see, the oil change procedure for the 2020 Jeep Wrangler is straightforward. The most difficult part of this maintenance is the removal of the oil filter and housing cap due to the tight location below the air intake pipe. It’s not the most ideal location, but to be fair – we’ve seen more questionable decisions from automotive engineers. If the intake pipe isn’t removed, it is helpful to have plenty of clean rags on hand to clean up spilled oil. Whether you choose to remove it, or work around it, it’s going to require a little extra time and effort.
