Jeep Wrangler Oil Capacity in Quarts and Compatible Oil Filter Part Numbers by Model Year

If you own a Jeep Wrangler and you're getting ready for an oil change, knowing the exact oil capacity in quarts and the compatible oil filter part number isn't just a nice-to-have it's the difference between a job done right and a costly mistake. Pour in too little oil, and your engine runs dry. Use the wrong filter, and you risk poor filtration or even a leak. This guide breaks down what you need for every Jeep Wrangler generation and engine so you can get in, get out, and get back on the trail.

How many quarts of oil does a Jeep Wrangler take?

The oil capacity depends on which engine sits under your hood. Jeep has offered several engines across the Wrangler's different generations the YJ, TJ, JK, and JL and each one has a slightly different appetite for oil.

Here's a breakdown by engine type:

2.5L 4-cylinder (YJ/TJ) approximately 4 quarts with filter change
4.0L inline-6 (YJ/TJ/LJ) approximately 6 quarts with filter change
3.8L V6 (2007–2011 JK) approximately 6 quarts with filter change
3.6L Pentastar V6 (2012–present JK/JL) approximately 6 quarts with filter change
2.0L turbo 4-cylinder (JL, 2018+) approximately 5 quarts with filter change
3.0L EcoDiesel V6 (JL, 2020+) approximately 10 quarts with filter change
6.4L Hemi V8 (392 Rubicon) approximately 7 quarts with filter change

Always check your owner's manual or the manufacturer's dipstick after filling. These numbers reflect oil capacity with a new filter installed. If you're reusing the old filter (not recommended), the capacity drops slightly usually by about half a quart.

What oil filter part number fits my Jeep Wrangler?

This is where a lot of people get tripped up. The oil filter isn't universal across Wrangler models. Using the wrong one can mean a poor seal, incorrect flow rate, or a filter that simply won't thread on.

Here are the most commonly used OEM and cross-referenced part numbers by engine:

2.5L 4-cylinder Mopar MO-090, Fram PH16, Purolator L14612
4.0L inline-6 Mopar MO-090, Fram PH8A, Purolator L14670, Wix 51394
3.8L V6 (JK) Mopar MO-409, Fram PH16, Purolator L14612
3.6L Pentastar V6 Mopar MO-899, Fram XG11665, Wix 57045, Royal Purple 10-48
2.0L turbo 4-cylinder Mopar 04892339AA, Mann W 811/80
3.0L EcoDiesel Mopar 68507598AA, Baldwin B40197
6.4L Hemi V8 Mopar MO-899, Fram XG11665, Wix 57045

Why does oil capacity and filter compatibility matter so much?

Your Wrangler's engine whether it's the older 4.0L inline-6 known for its reliability or the newer 3.6L Pentastar relies on a precise amount of clean oil to keep moving parts lubricated and cool. Too little oil means increased friction and heat. Too much oil can cause foaming, which reduces lubrication just as badly.

The oil filter does the heavy lifting of trapping dirt, metal shavings, and sludge before that oil cycles back through the engine. A filter that doesn't match your engine's flow rate or pressure specs can either bypass too early (letting contaminants through) or restrict flow and starve the engine.

What happens if I use the wrong oil filter?

A few things can go wrong, and none of them are good:

Oil leaks A filter with the wrong gasket size won't seal properly against the mounting surface.
Low oil pressure A filter with too much internal resistance can reduce oil flow to critical engine components.
Poor filtration If the filter media isn't rated for your engine's flow, particles can pass through unfiltered.
Filter won't fit This one's obvious, but it happens more than you'd think when people grab a filter off the shelf without checking the application chart.

What type of oil should I use in my Jeep Wrangler?

Jeep recommends specific oil viscosities based on engine and climate. Here's a quick reference:

4.0L inline-6 10W-30 (normal conditions) or 5W-30 (cold climates)
3.8L V6 5W-20
3.6L Pentastar 0W-20 (full synthetic required)
2.0L turbo 0W-20 (full synthetic required)
3.0L EcoDiesel 5W-40 full synthetic (check for API CK-4 or SN Plus rating)
6.4L Hemi 0W-40 full synthetic

Full synthetic oils cost more per quart, but they hold up better under the heat and stress that Wrangler engines deal with especially during towing, crawling, or highway driving in warm weather.

How often should I change the oil in my Jeep Wrangler?

Most Wrangler owners should plan on an oil change every 5,000 to 7,500 miles if using synthetic oil. If you use conventional oil, aim for every 3,000 to 5,000 miles. Jeep's Oil Change Indicator system (on newer models) monitors driving habits and engine load to give you a more precise alert trust it, but don't push it too far past the recommendation.

If you frequently off-road, tow, drive in dusty conditions, or make a lot of short trips, lean toward the shorter end of that interval. Dirty, hot, and stressed oil breaks down faster.

Can I change the oil myself, or should I go to a shop?

Changing the oil on a Jeep Wrangler is one of the more straightforward DIY maintenance jobs. The oil drain plug is easy to access, and the oil filter is reachable from underneath. You'll need:

The correct amount of fresh oil (check the quarts listed above)
A compatible oil filter (matched to your engine)
A drain pan, socket wrench (usually 13mm for the drain plug), and an oil filter wrench
A new drain plug washer (recommended to prevent seeping)
Jack stands or ramps if you need extra clearance

The whole process takes about 30 minutes once you've done it a couple of times.

Common mistakes Jeep Wrangler owners make during an oil change

These come up a lot in forums and at shops:

Over-tightening the oil filter Hand-tight plus a quarter turn is enough. Over-tightening crushes the gasket and can cause leaks or make removal a nightmare.
Forgetting to pre-fill the filter A thin coat of fresh oil on the filter gasket and a partial fill helps prevent a dry start.
Not checking the old filter's gasket Sometimes the old gasket sticks to the engine block. If you mount a new filter on top of it, you'll get a double-gasket situation and an oil leak.
Using the wrong drain plug torque The aluminum oil pan on Pentastar engines strips easily. Torque it to spec (usually around 20 ft-lbs) and don't crank on it.
Ignoring the oil type Just because 5W-30 worked on your old 4.0L doesn't mean it's right for your 3.6L. Use what the manufacturer specifies.

What should I do before my next oil change?

Take a few minutes to confirm your exact engine size. Pop the hood and check the engine cover label or look up your VIN on Jeep's owner portal. Then match that engine to the oil capacity and filter part number from the lists above. Buy the oil and filter together before you start running to the auto parts store mid-job with oil draining onto your driveway is no fun.

Quick checklist before your next oil change:

Confirm your engine size (2.5L, 3.6L, 4.0L, etc.)
Check the correct oil capacity in quarts for your engine
Match the right oil filter part number
Buy the correct oil viscosity and amount
Have a drain pan, wrench, and filter wrench ready
Inspect the old filter gasket after removal
Torque the drain plug to spec don't over-tighten
Start the engine after filling and check for leaks around the filter and drain plug
Reset your oil change indicator if your Wrangler has one
Record the mileage and date for your next interval

Getting the oil capacity and filter right isn't complicated it just takes a few minutes of attention before you turn a wrench. Your Wrangler will return the favor with years of reliable miles on and off the road.
