To ensure your Jeep’s dependability for the long haul, it’s important to keep up with its scheduled maintenance. Therefore, if you frequently take your Jeep wheeling, you should maintain a schedule of regular oil changes.

However, the procedure is universal for all models equipped with the 3.6 pentastar motor and extremely similar for those with the 3.8 litre engine.

The following procedures can be used as a guide while attempting to change the engine oil in your Jeep.

Jeep Wrangler Oil Change: How to Tutorial

1. Remove The Plastic Engine Cap

The top of your Jeep Wrangler engine is shielded by a plastic engine cap, which may be removed. It’s not fixed in place, so just grip the front with both hands and pull up to remove it. Once you remove the cap, you’ll have access to the top of your engine, where you’ll find the oil filter and the oil filling cap.

2. Empty the Used Oil

Make sure your oil catch pan is under your Jeep so it can collect any old oil. To take off the drain bolt, first loosen it with your ratchet and a 13mm socket, and then take it off by hand. Because of gravity, oil will drain out quickly, so be ready to quickly take your hand and the drain bolt off. Let the oil drain for a few minutes before continuing for the best results.

3. Replace Your Oil Filter

You may change the oil filter in your Jeep while the old oil is pouring out. Returning to the top of the engine compartment, you will need to loosen the oil filter using a ratchet and a 24 mm socket before you can pull it out by hand.

Keep a rag handy in case the oil filter leaks and you need to clean up any spills. When you’ve extracted the filter, you can unhook it from the top by giving it a light tug.

There is an O-ring on top of the cap that needs to be taken off. The old ring on your oil filter will be replaced with a new one in your new oil filter. To remove the old O-ring, pull it loose with a flat head screw driver and then roll it off.

The new O-ring should be rolled into position to secure it. Then, after replacing the cap’s O-ring and plastic threads, you should dip a clean finger into fresh oil and rub it all over the new parts. Put the new filter in place by gently pushing it into the cap. You can now reinstall the new filter into the engine. Replace the cap and ensure it fits snugly.

4. Adjust Your Drain Plug

Put the oil drain plug back in and return to working beneath the Jeep. When it comes to proper torque, consult your vehicle’s manual. To avoid grime and filth accumulation, wipe out the oil pan with a clean towel to remove any oil that has pooled at the bottom.

5. Add The New Oil

It’s time to re-fill the oil in your car’s engine. An easily accessible oil filler cap is located on the motor’s driver side. You can begin adding oil by using a funnel to do so.

The correct oil weight (viscosity) can be found in the owner’s handbook. To get the oil moving, we prefer to put in five quarters and turn on the engine for a brief moment. Then, after the engine has been turned off, check the fluid level and add the final quart.

6. Get It Done

When you’re done, put away your tools and give them a good cleaning. While the hood is up, we also check for leaks, loose bolts, and other potential trouble spots by carefully examining each component with a flashlight. And finally, don’t forget to keep track of your miles and schedule your next oil change reminder.

The oil change process for a Jeep Wrangler is clearly simple. The close position of the oil filter and housing cap underneath the air intake pipe makes its removal the most challenging component of this repair.

You can now keep track of your Jeep’s mileage and schedule a reminder for when the oil needs to be replaced because you successfully changed the oil in the engine. Keeping track of your vehicle’s mileage and service history is easy with any number of available apps.

Frequently Asked Questionns

How often do Jeep Wranglers need oil change?

The Wrangler’s Owner’s Manual recommends changing the oil and filter when the Oil Change Indicator System alerts you to do so, but recommends intervals not exceed 12 months or 10,000 miles, whichever comes first.

How long can a Jeep run without oil?

Without oil, the engine runs for around 15 minutes without bursting into a cloud of smoke, but taking it apart reveals some serious damage. Lacking proper lubrication, all the metal components in the engine rub against each other, causing an incredible amount of premature wear.

What are the symptoms of low oil in a car?

Symptoms of Low Engine Oil
Oil pressure warning light.
Burning oil smell.
Strange noises.
Weaker performance.
Overheating Engine

What happens if my oil is low?

When your engine oil is running low, it stops lubricating the engine components. When these parts are no longer well-oiled, they cause loud clunking, knocking, and grinding sounds. This can cause your rods to break, which will give off the knocking sound from underneath the hood of your vehicle.
