Your 2015 Jeep Cherokee needs SAE 0W-20 full synthetic oil to keep its engine running smoothly. This is the exact answer to the question “what kind of oil does a 2015 jeep cherokee take.” Using the right oil protects your engine, improves fuel economy, and prevents costly repairs down the road.
Many owners get confused when they see different oil weights at the store. Don’t worry—we’ll break it down simply. Your Cherokee’s engine was designed for 0W-20, and sticking with it is the best choice.
Let’s walk through everything you need to know about oil for your 2015 Jeep Cherokee. From viscosity to capacity to change intervals, we’ve got you covered.
What Kind Of Oil Does A 2015 Jeep Cherokee Take
The 2015 Jeep Cherokee takes SAE 0W-20 full synthetic motor oil. This is the factory recommendation from Jeep for all engine options in this model year. Using anything else could void your warranty or cause engine damage over time.
Jeep specifically requires full synthetic oil, not conventional or synthetic blends. Full synthetic provides better protection at extreme temperatures and keeps your engine cleaner longer.
Engine Options And Their Oil Requirements
The 2015 Cherokee came with three engine choices. All of them use the same oil type and viscosity. Here’s a quick breakdown:
- 2.4L Tigershark I4 engine – Uses 0W-20 full synthetic, capacity is 5.5 quarts with filter
- 3.2L Pentastar V6 engine – Uses 0W-20 full synthetic, capacity is 6.0 quarts with filter
- 2.0L turbo diesel (Europe only) – Uses 5W-30 full synthetic, not common in North America
If you have the 2.4L or 3.2L gas engine, stick with 0W-20. The diesel version is rare, so most readers will use the standard recommendation.
Why 0W-20 Is The Right Choice
0W-20 oil is thin when cold, which helps your engine start easier in winter. The “0W” means it flows at very low temperatures. The “20” means it thickens enough at operating temperature to protect engine parts.
Modern engines like the ones in your Cherokee have tight tolerances. Thicker oil like 5W-30 or 10W-30 might not flow properly through small passages. This can lead to inadequate lubrication and premature wear.
Using 0W-20 also helps your Cherokee meet fuel economy standards. Thinner oil reduces drag on moving parts, which saves gas. You might lose 1-2 MPG by using heavier oil.
Oil Capacity For A 2015 Jeep Cherokee
Knowing how much oil your engine needs is just as important as knowing the type. Overfilling or underfilling can cause problems.
2.4L Tigershark I4 Capacity
The 2.4L engine holds 5.5 quarts of oil when you include the filter. If you’re doing a DIY oil change, buy a 5-quart jug and a 1-quart bottle. You’ll use most of both.
Always check the dipstick after adding oil. Start with 5 quarts, run the engine for a minute, then check and add more as needed. The final amount is usually around 5.5 quarts.
3.2L Pentastar V6 Capacity
The 3.2L V6 holds 6.0 quarts of oil with filter. Buy a 5-quart jug and two 1-quart bottles. You’ll use one full quart from the second bottle.
Some owners report that their V6 takes slightly less or more depending on how long the oil drains. Always verify with the dipstick before calling it done.
Recommended Oil Brands For Your Cherokee
You don’t need to buy expensive boutique oils. Any brand that meets the required specifications will work fine. Here are some trusted options:
- Pennzoil Platinum – Full synthetic, meets Chrysler MS-6395 spec
- Mobil 1 – Advanced full synthetic, widely available
- Castrol Edge – Full synthetic with titanium technology
- Valvoline Advanced – Full synthetic, good value
- Amazon Basics – Surprisingly good quality for the price
Look for the API “SN” or “SN Plus” rating on the bottle. This ensures the oil meets current industry standards. Also check for the Chrysler MS-6395 specification, which is Jeep’s own requirement.
Can You Use Synthetic Blend Or Conventional Oil?
Technically yes, but it’s not recommended. Your Cherokee’s engine was designed for full synthetic oil. Using conventional oil might save you $10-15 per change, but it won’t protect as well.
Full synthetic oil resists breakdown better, handles high temperatures, and keeps sludge from forming. For a vehicle that’s now nearly a decade old, good oil is cheap insurance.
If you absolutely must use conventional oil in an emergency, use 0W-20 conventional. Then change it back to full synthetic as soon as possible. Mixing the two types is fine, but you’ll lose some synthetic benefits.
How Often To Change Oil In A 2015 Cherokee
Jeep recommends oil changes every 6,000 miles or 6 months, whichever comes first. This applies to normal driving conditions. If you drive in severe conditions, change it more often.
Severe Driving Conditions Include
- Frequent short trips (under 5 miles)
- Extreme hot or cold weather
- Dusty roads or off-road driving
- Towing or carrying heavy loads
- Stop-and-go city traffic
For severe conditions, change the oil every 3,000-4,000 miles. This keeps contaminants from building up and protects your engine better.
Your Cherokee’s oil life monitor system will tell you when it’s time. It doesn’t just count miles—it tracks driving habits and conditions. Trust it, but don’t exceed 6,000 miles even if the monitor says you can go longer.
Step-By-Step Oil Change Guide For 2015 Cherokee
Changing your own oil saves money and ensures it’s done right. Here’s how to do it safely.
Tools And Materials Needed
- 5-6 quarts of 0W-20 full synthetic oil
- New oil filter (Mopar or quality aftermarket)
- Oil filter wrench
- Socket set (15mm for drain plug)
- Drain pan
- Funnel
- Rags or shop towels
- Jack and jack stands (or ramps)
Step 1: Prepare The Vehicle
Park on level ground and let the engine cool for 10-15 minutes. Warm oil drains better, but hot oil can burn you. Find a safe temperature.
Jack up the front of the Cherokee and secure it on jack stands. Never work under a car supported only by a jack. Use ramps if you have them—they’re safer and easier.
Step 2: Drain The Old Oil
Place the drain pan under the oil pan. Locate the drain plug—it’s a 15mm bolt on the bottom of the engine. Remove it with a socket wrench.
Let the oil drain completely. This takes 5-10 minutes. While it drains, inspect the drain plug gasket. Replace it if it’s worn or flattened.
Step 3: Remove The Old Filter
The oil filter is located on the side of the engine. On the 2.4L, it’s near the front. On the 3.2L, it’s on the driver’s side. Use an oil filter wrench to loosen it.
Be careful—the filter will be full of hot oil. Let it drain into the pan before removing it completely. Wipe the filter mounting surface clean.
Step 4: Install The New Filter
Rub a little fresh oil on the new filter’s rubber gasket. This helps it seal properly and makes removal easier next time. Screw the filter on by hand until it contacts the engine.
Tighten it another 3/4 turn by hand. Don’t overtighten—you’ll damage the gasket or make it impossible to remove later.
Step 5: Add New Oil
Reinstall the drain plug and tighten it to 25 ft-lbs. Don’t overtighten or you’ll strip the threads. Pour in about 5 quarts of oil for the 2.4L or 5.5 quarts for the 3.2L.
Replace the oil fill cap. Start the engine and let it run for 30 seconds. Check for leaks around the drain plug and filter. Turn off the engine and wait 2 minutes.
Step 6: Check The Level
Pull out the dipstick, wipe it clean, reinsert it, and check the level. Add oil slowly until it reaches the full mark. Don’t overfill—too much oil can cause foaming and engine damage.
For the 2.4L, you’ll likely need about 5.5 quarts total. For the 3.2L, about 6.0 quarts. Write down the mileage and date for your records.
Common Oil-Related Problems In 2015 Cherokees
Some owners report issues with oil consumption in the 2.4L engine. This is a known concern. If your Cherokee uses more than 1 quart every 1,000 miles, it might need attention.
Check your oil level every other gas fill-up. Low oil can cause the engine to run rough or trigger warning lights. Keep a quart of 0W-20 in your trunk just in case.
Another issue is oil leaks from the valve cover gasket or oil filter housing. These are more common on higher-mileage vehicles. If you see oil spots under your Cherokee, have it inspected.
What About Oil Additives?
You don’t need them. Modern synthetic oils already contain detergents, anti-wear agents, and viscosity improvers. Adding extra products can upset the chemical balance.
If your engine has high mileage (over 100,000 miles), you might consider a high-mileage formula. These contain seal conditioners that help reduce leaks. Brands like Mobil 1 and Valvoline offer high-mileage 0W-20 options.
Where To Buy Oil For Your Cherokee
You can find 0W-20 full synthetic oil at most auto parts stores, Walmart, and online retailers. Prices vary, so shop around.
- Walmart – Usually has the best prices on major brands
- AutoZone – Good selection, frequent sales
- Amazon – Convenient if you buy in bulk
- RockAuto – Good for Mopar filters and oil
Buy oil in 5-quart jugs—they’re cheaper per quart than individual bottles. Keep a spare quart for top-ups between changes.
