If you drive a Jeep Cherokee 2018, you probably know how important engine oil is for your SUV’s health. The right oil type keeps your engine running smooth, boosts performance, and even helps your vehicle last longer.
But with so many oil types and brands out there, it’s easy to feel lost. This guide explains exactly what oil your Jeep Cherokee 2018 needs, how to choose the best one, and some practical tips to keep your engine in top shape.
Recommended Oil Type For Jeep Cherokee 2018
The 2018 Jeep Cherokee comes with different engines, and each engine has its specific oil needs. Most Cherokee models use either the 2.4L Tigershark or the 3.2L Pentastar V6 engine.
- 2.4L Tigershark: This engine requires SAE 0W-20 full synthetic oil.
- 3.2L Pentastar V6: This engine uses SAE 5W-20 full synthetic oil.
Both engines need full synthetic oil for the best protection and performance. Synthetic oils handle high temperatures better and protect engine parts more effectively than conventional oils.
Why Oil Type Matters
Choosing the right oil isn’t just about ticking a box in your manual. The oil viscosity (like 0W-20 or 5W-20) directly affects how your engine starts, runs, and ages.
- 0W-20: Flows easier in cold weather, protecting your engine at startup.
- 5W-20: Slightly thicker, but still gives excellent protection and fuel efficiency.
Using the wrong oil can hurt your engine. For example, thick oil can slow down lubrication and cause more wear, while thin oil might not protect enough at high temperatures.

Jeep Cherokee 2018 Oil Capacity
Knowing how much oil your engine needs is just as important as picking the right type.
- 2.4L Tigershark: Needs about 5.5 quarts (with filter change).
- 3.2L Pentastar V6: Needs about 5.9 quarts (with filter change).
Overfilling or underfilling can cause engine problems, so always check your oil level with the dipstick after an oil change.
Oil Change Intervals
For most drivers, full synthetic oil in a 2018 Jeep Cherokee should be changed every 7,500 miles or 12 months, whichever comes first. However, if you drive in tough conditions—like towing, extreme heat, or lots of short trips—change it every 5,000 miles.
Don’t trust the oil life monitor alone. Sometimes, it doesn’t account for tough driving conditions. Always check your oil level monthly and look for signs of dirty or low oil.
Comparing Popular Oil Brands For Jeep Cherokee 2018
Here’s a quick look at some trusted synthetic oils:
| Brand | Viscosity | API Rating | Special Features |
|---|---|---|---|
| Mobil 1 | 0W-20, 5W-20 | SN Plus | Advanced wear protection |
| Pennzoil Platinum | 0W-20, 5W-20 | SN Plus | Cleans pistons better |
| Castrol EDGE | 0W-20, 5W-20 | SN Plus | Strong under pressure |
Any of these oils will meet the needs of your 2018 Cherokee as long as you pick the right viscosity.
How To Choose The Right Oil Filter
A good oil filter is just as important as the oil itself. For the Jeep Cherokee 2018:
- Always use filters that meet Mopar or OEM standards.
- Popular options: Mopar MO-349, Fram XG10060, or Wix 57356XP.
A quality filter traps harmful particles and keeps your oil clean longer.

Practical Oil Change Tips
Changing your own oil? Here are a few things that make the job easier and safer:
- Warm up your engine for 5 minutes before draining. Warm oil flows out faster.
- Always replace the oil drain plug gasket if needed.
- Check the oil level after running the engine for a minute. Add oil if needed.
- Dispose of used oil properly—never pour it down a drain.
Many beginners forget to replace the oil filter or over-tighten the drain plug. Both can cause leaks. Always tighten the plug to the recommended torque.
Comparing Synthetic Vs. Conventional Oil
Some drivers wonder if they can use cheaper, conventional oil. Here’s how the two compare:
| Type | Engine Protection | Change Interval | Cost |
|---|---|---|---|
| Synthetic | Excellent | 7,500 miles | Higher |
| Conventional | Good | 3,000 miles | Lower |
Synthetic oil is always best for the Jeep Cherokee 2018. It costs more, but you change it less often and your engine lasts longer.

Common Mistakes When Choosing Oil
- Ignoring the Owner’s Manual: Always check your manual for the correct oil type and capacity.
- Mixing Oil Types: Don’t mix synthetic and conventional oil.
- Buying Cheap Filters: Low-quality filters can cause engine damage.
- Not Checking for Leaks: After an oil change, look under your car for leaks.
- Waiting Too Long Between Changes: Delayed oil changes cause sludge build-up.
Many people think “oil is oil. ” But small mistakes can lead to expensive repairs down the road.
Environmental Tips
Used oil is hazardous waste. Always recycle it at a certified collection center. Never dump oil on the ground or down drains—it pollutes water and soil.
You can find recycling locations at most auto parts stores or by checking the EPA’s website.
