Changing the engine oil is a necessary part of routine Jeep maintenance and really, it’s something that anyone can do. In fact, thanks to the design of the 3.6L V6 Pentastar engine in a Wrangler JK, it’s something that’s easier to do than ever before.
The new Pentastar engine does not use a traditional can style oil filter but rather, uses a disposable filter media that is installed into the top of the engine. This makes changing your engine oil super easy and eliminates most of the mess.
This short write-up will explain in detail what is involved in the process of a Jeep JK 3.6L Pentastar engine oil change and just how little you will need to do. The entire project takes about 30 minutes. And after you’ve done this on your own, I can almost guarantee you’ll never take your Jeep back to your dealer or a shop to have it done for you again.
The mileage time frame for an oil change is not an exact science these days. While many still swear by the old 3,000 mile rule, today’s engines and oil blends do allow for a longer duration between changes. In fact, Jeep owner’s manual doesn’t really tell you exactly when to change oil, it just mentions that depending on operating conditions, the “change oil” message may appear as early as 3,500 miles since last reset. It does say however that you should never exceed 8,000 miles or six months between oil changes.
It is my personal opinion that you should switch from conventional oil to synthetic oil as soon as you have a chance. There are many opinions on this topic, but I made a switch after first two oil changes, and ever since the third one started using synthetic oil only. Many cars however come with synthetic oil from factory so there is no need to wait to make a switch.
Ever since I started using synthetic oil I have been putting about 10,000 miles between oil changes and my Jeep runs great, even in the hot Arizona climate. My Jeep is a daily driver but it’s not a road trip vehicle so the oil changes happen once a year or so.
Disclaimer: Like I always mention I am not a professional mechanic, I just try to do as much work on my Jeep as possible. It helps me learn more about my vehicle and save some money that can be spent on parts and upgrades.
I take no responsibility for any injury or breakage which might occur if you decide to follow these steps. You have to decide if you’re comfortable working on your Jeep. If you’re not, please have a professional do the oil change for you.
