If you own a Jeep Wrangler, it is an essential to change its engine oil regularly. The best thing about changing a jeeps engine oil is that you can do it by yourself and it requires just a few tools.

In some modern jeep engines, for instance, the 3.6L V6 Pentastar engines use the disposable filter media that make oil change procedure very easy.

If you think it’s time to change your jeep’s engine oil, you can follow the following steps to make your work easier and error-free.

Required Tools

  • Gloves

  • Flat-head screwdriver

  • Funnel

  • Oil drain container

  • 13mm socket and ratchet

  • Oil filter

Step 1: Removing the Engine Cap

The engine cap is a removable plastic cap covering the top of your jeeps engine. This cap is easy to remove because it is not bolted. Simply grab and pull it up with your hands. After removing the cap, you will see the oil filter and an oil filter cap. These are the ones you need to access to do an oil change.

Step 2: Drain the Used Oil

Place your oil drain container under your jeep to collect the used oil. With the 13mm socket ratchet, loosen the drain bolt and be careful to avoid opening it completely.

Remove the drain bolt with your fingers and allow the oil to splash into the correcting pan. The oil flows out using gravity, and in some cases, it may take some time before the oil starts flowing out. You can hold the correcting pan closer to the draining plug to avoid splashing.

Step 3: Change the Oil Filter

While the oil is draining out of your jeep engine, you can start replacing your oil filter. Using a 24mm socket, loosen and remove the oil filter using your hand.

You can use a piece of cloth to clean oil from the oil cap just in case the used oil drops from the filter. Then gently pull the cap to separate it from the filter.

Use the flat-head screwdriver to open the o-ring at the top of the oil cap. New oil filters come with replacement rings. Replace the O-ring with the new one on your oil filter.

Dip a clean piece of cloth or your finger into the new oil and rub it on the ring and plastic threads on your oil cap. Smoothly push the new oil filter into oil cap until it fits perfectly. After installing the filter into the cup, return the cup gently into position.

Step 4: Tighten Drain Plug

Go under you jeep and with your fingers roll the oil drain plug into position. For torque tightening requirements, you can refer to your users guide for more information. Use a piece of clean cloth to wipe the surface of the oil pan to prevent dust and dirt from sticking on it.

Step 5: Add New Oil

Finally, it is time to add new oil into your jeeps engine. Unscrew and remove the oil filter cap. The oil filter cup is located on the driver’s hand side and can be easily removed with hands.

Start adding oil into the jeeps using a funnel. The amount and viscosity of oil that you will add depends on your jeeps model.

You can refer to the users manual for more information. If for instance, if your jeep model requires six quarters of oil, you can start by adding five quarters.

Start the engine and allow the oil to circulate to all part. Stop the engine and now add the last one quarter until full.

Step 6: Finish Up

After adding the oil, clean and store your tools in a safe place. You can use a flashlight to check if everything is working as expected; all bolts are tight, and no oil is leaking.

Now that you have successfully changed your Jeep Wrangler engine oil, you can start recording your mileage and set a reminder for the next oil change. There are plenty of applications for monitoring mileage and maintenance records to choose from.
