The 2019 Jeep Wrangler has an oil capacity of 5 quarts and requires either SAE 5W-30 or SAE 0W-20 motor oil, depending on the engine.
For your Wrangler’s engine to function properly, its moving parts need to be kept lubricated by motor oil—oil that, over time, collects byproducts and contaminants from the combustion process. To keep the engine running smoothly, motor oil needs to be changed from time to time—failure to do so can result in irreparable damage.
Before you can change your Jeep’s oil, however, you’ll need to know how much to buy—that’s why we’ve put together the following guide breaking down everything you need to know about the 2019 Jeep Wrangler’s oil capacity, the type of oil it needs, and when/how to change it.

Regardless of which engine is underneath the hood of your 2019 Jeep Wrangler, the total oil capacity remains the same: 5 quarts or roughly 4.7 liters.
What type of oil does the 2019 Jeep Wrangler use?
Oil type, on the other hand, does depend on your 2019 Jeep Wrangler’s engine, and for the 2019 model year, the Wrangler was offered with either a 2.0-liter 4-cylinder or 3.6-liter V6 engine. (The 2.0-liter and 3.6-liter measurements represent the engine’s displacement, or the space occupied by the engine cylinders.)
- If your 2019 Jeep Wrangler is equipped with the smaller 2.0-liter 4-cylinder engine, you’ll need to use API SN PLUS Certified SAE 5W-30 full-synthetic motor oil that meets FCA Material Standard MS-13340 requirements.
- For those with the larger 3.6-liter V6 engine, it is recommended that you use API Certified SAE 0W-20 full-synthetic motor oil which meets FCA Material Standard MS-6395 requirements.
Okay, but what do those numbers actually mean? If this is your first venture into the world of oil ratings, keep reading for an in-depth look at how to interpret them.
An oil’s winter rating is indicated by the first number and tells us how thick or thin the oil will be when subjected to very cold temperatures—as a general rule, the lower the number, the thinner the oil will be. Oils with a winter rating of “5” still fare pretty well in the cold, but “0” is the best for freezing temps and winter driving, as it is extremely thin and makes starting your engine much easier.
On the flip side, the second number in an oil rating speaks to the oil’s viscosity when heated to extremely high temperatures of 216℉ or higher, a.k.a. the normal operating temperature of an engine. Oils with either a “30” or “20” rating will be extremely thin when heated to such temps.
How often does a 2019 Jeep Wrangler need an oil change?
Seeing as the 2019 Jeep Wrangler uses full-synthetic motor oil—which lasts longer than its conventional counterpart—you only need to perform an oil change once every 10,000 miles, which amounts to roughly once per year.
If your 2019 Jeep Wrangler is regularly subjected to severe conditions—such as dusty/sandy roads or long periods of low idling—however, you will need to change your oil more frequently, or once after every 4,000 miles.
In any case, it is recommended that you check your Jeep’s oil level/condition at least once a month and before long trips to avoid potentially damaging your engine. During these inspections, keep an eye out for the following symptoms which suggest an oil change is needed sooner rather than later:
- You can smell oil or a burning odor from inside the car’s cabin
- The oil’s color has changed to dark brown or black
- The dashboard oil pressure light is illuminated
- The oil’s texture looks gritty or grainy
- The overall performance of your car has worsened
How to change your oil and oil filter
If you plan on changing your 2019 Jeep Wrangler’s oil yourself, you’ll need the following supplies: five quarts of 5W-30 or 0W-20 motor oil, a new filter, an oil drain pan, a socket wrench set, and a filter wrench to remove the old filter.
Once you’ve got your tools together, switch the ignition on and let the engine run for four to five minutes or until it reaches its normal operating temperature—when the engine is hot, shut it off, pop the hood, and follow the steps below:
- Locate the oil reservoir and unscrew the oil fill cap. Set the cap aside in a secure location.
- Place the oil drain pan directly beneath the reservoir's drain hole.
- Select the correct size socket and use your socket wrench to remove the drain bolt and washer. Once removed, oil will start to empty into the drain pan.
- Use the filter wrench to remove the old filter and install the new one while the oil drains.
- When the flow of oil stops, replace the drain bolt after threading a new washer into place.
- Add clean oil to the reservoir and replace the oil cap.
After adding clean oil, start your car and let it run for about 30 seconds. Turn off your car, then use a dipstick to confirm that the oil has reached the "MAX FILL" line. Add more oil to top it off if necessary.
Start the engine one last time and let it run while you check for leaks. If everything looks good, the oil pressure warning light on your 2019 Jeep Wrangler’s dashboard may shut off automatically or you may need to reset it manually.
Finally, it's crucial that you correctly dispose of the used oil. Instead of emptying the oil from the drain pan into the garbage, transfer it to a container that can be sealed and bring it to your neighborhood recycling center or an auto parts store that accepts used oil.
