A 2013 Jeep Wrangler equipped with the standard 3.6L six-cylinder engine has a total oil capacity of exactly 6 quarts, or approximately 5.6 liters, and requires 5W-20 motor oil.
When it comes to keeping your Jeep’s engine healthy, lubricated, and fit for adventuring, regular oil changes are the easiest way to do it—failing to replace your oil on a regular basis can lead to costly and irreversible engine damage.
But before you can go about changing your oil yourself, you need to know how much oil the engine requires—that’s why we’ve put together this comprehensive

For the 2013 model year, all Jeep Wranglers were outfitted with the same 3.6L six-cylinder engine, which has a total oil capacity of exactly 6 quarts, or roughly 5.6 liters.
As you can see, oil capacity is not the same as the engine’s displacement, or the 3.6L space occupied by the engine’s six cylinders. It can be easy to confuse the two numbers, but they are not interchangeable and filling your engine with only 4 liters of oil can have disastrous consequences.
What type of oil does the 2013 Jeep Wrangler 3.6L need?
Now that you know how much oil your 2013 Jeep Wrangler 3.6L can hold, let’s take a look at what type of oil it needs—after all, not all motor oil has the same qualities or properties, and using the wrong one can wreak havoc on your engine.
According to the owner’s manual, a 2013 Jeep Wrangler 3.6L requires SAE 5W-20 motor oil—and while those numbers may not mean much to you, they tell us a lot about the oil’s viscosity at certain temperatures.
The first number refers to the oil’s winter rating, or how thick the oil will be when subjected to extremely cold temperatures—the lower the number, the thinner the oil is going to be. Any oil with a “5” winter rating will be very thin even during the coldest months, making it that much easier to start your vehicle on brisk mornings.
The “20,” on the other hand, tells us what the oil’s viscosity is like when heated to extremely high temperatures of 196 degrees F or more—a.k.a. the standard operating temperature of an engine. Any oil rated as “20” here will be very, very thin at such high temps.
How often does the 2013 Jeep Wrangler 3.6L need an oil change?
It is generally recommended that you
change your 2013 Jeep Wrangler 3.6L’s oil
after every 3,000 to 5,000 miles, which amounts to roughly two to three times per year—keep in mind, however, that this estimate is based on the nation’s average driving habits and conditions, which means you may need to change your oil more frequently if you often tow heavy loads or regularly take your Jeep off-road.This does not, however, mean that you can get away with not checking your oil between those intervals—in fact, most automotive experts recommend that you check your oil level/condition at least once a month to avoid potentially damaging your vehicle.
During these routine checks, keep an eye out for the following signs an oil change is needed sooner rather than later:
- Oil has changed from a clear amber to a dark brown or black color
- Engine starts making unusual noises
- You notice an oily, smoky, or burning smell in the vehicle
- Oil is gritty or grainy to the touch, as though there were sand in it
- The oil pressure warning light turns on
How to change your oil and oil filter
If you’re not opposed to getting your hands dirty, changing your Jeep’s oil at home is an easy way to save a couple hundred dollars each year—all you need is an oil drain pan, socket wrench set, and a filter wrench, as well as a new filter and 6 quarts of 5W-20 motor oil.
Once you’ve got your supplies together, start your vehicle and let the engine run for four to five minutes until the engine reaches its normal operating temperature. When the engine is hot, shut it off, pop the hood, and do the following:
- Locate the oil reservoir and unscrew the oil fill cap. Place the cap aside, somewhere you won’t lose it.
- Position the oil drain pan underneath the reservoir’s drain bolt hole.
- Use the socket wrench to remove the drain bolt and accompanying washer—oil will start flowing into the drain pan below.
- As the oil drains, remove the old filter with the filter wrench and install the clean filter.
- When the flow of oil stops, replace the drain bolt and thread a new washer into place.
- Pour new oil into the reservoir. Replace the oil fill cap.
After you add the clean oil, start your vehicle, let it run for a few seconds, and shut it off again. Use a dipstick to check the oil level—if it does not reach the “MAX Fill” line, add more oil.
Switch your Jeep’s engine on a final time and let it run for a few minutes while you check underneath the vehicle for leaks. As long as everything looks good, you’re all set to manually reset the oil pressure warning light.
Finally, you’ll need to dispose of the old oil—this can be done by emptying the drain pan into a sealable container and taking it to your local recycling center.
