The 2011 Jeep Wrangler's oil capacity is 6.0 qt or 5.7 L (including filter). You should change out the oil filter every time you perform an
oil change
. Be sure not to confuse the engine’s oil capacity with the engine’s displacement. The 2011 Jeep Wrangler is powered by a 3.8-liter V6 engine. “3.8 liters” here tells you the volume of the engine’s pistons and is used to communicate an engine's size. Engine displacement is not the same as the oil capacity.
What kind of oil does a 2011 Jeep Wrangler need?
The next step in your endeavor to purchase oil for your 2011 Jeep Wrangler is knowing which oil to choose. Jeep recommends using an SAE 5W-20 Engine Oil with the API Certification Seal for Gasoline Engines.
5W-20 oil is a relatively low-viscosity (thin) oil at cold-start temperatures and normal operating temperatures. This means it will help improve engine performance in cold weather conditions and stay smooth and lubricating even when the engine is working hard.
Jeep recommends conventional oil, but the owner’s manual also states that synthetic motor oil can be used so long as it meets the same viscosity grade and quality certification.
Regardless of whether you choose to use conventional or synthetic oil in your Wrangler, it is typically best practice to pick one and stick to it. If you have a high-mileage vehicle, then you might want to consider switching to high-mileage synthetic engine oil to help improve your engine’s performance.
How often to change oil on a 2011 Jeep Wrangler
The typical rule of thumb for conventional oil is every 3,000 to 5,000 miles, or every six months, whichever comes first. You should never exceed 8,000 miles or six months.
If you choose to switch to synthetic oil, one of the major benefits is a longer change interval. It is best to follow any recommendations provided by the oil manufacturers, but generally, experts recommend replacing synthetic engine oil every 7,500 to 10,000 miles.
The best advice is to simply check your oil regularly and keep an eye, ear, and nose out for any signs and symptoms that it’s time for an oil change, including:
- Dark brown or black oil on your dipstick. Clean oil should be light brown or amber and somewhat transparent
- Oil that feels coarse or gritty
- Strange noises and smells coming from the engine, especially burning, oil, or smoke smells
- Changes in your vehicle's performance, like decreased fuel efficiency or accelerating power
How to change your oil and oil filter
You can always take your Jeep to a local shop to do the oil change for you, but you can save yourself money by doing it at home.
If you’ve decided that you want to change your oil at home, it’s time to gather your tools. You’ll need a socket wrench, a drain pan, a fresh oil filter, a filter wrench, and of course, 6 quarts of 5W-20 engine oil.
Start by running the engine for a few minutes to bring it up to normal operating temperature. Once you’re there, shut off the engine, pop the hood, and follow these steps:
- Remove the oil fill cap
- Under the engine, position the oil drain pan and remove the old drain bolt and washer
- Remove the old oil filter and let the oil drain completely
- Install the new filter
- Replace the oil drain bolt with a new washer and tighten it to 29 lb-ft
- Fill the engine with 6 qt of clean oil
- Check the dipstick and top up as needed
- Replace the oil fill cap
- Turn your engine on and let it run for a minute, looking for any leaks
Once you’re done, take the old oil to a recycling center to dispose of it responsibly. Do not throw your dirty oil in the garbage, down the drain, or into the gutter.
