Choosing the right oil for your 2019 Jeep Grand Cherokee is more important than many drivers realize. The oil you use directly affects your SUV’s engine life, performance, and fuel economy.
If you want your Grand Cherokee to run smoothly for years, using the correct oil type and change intervals is essential.
This guide explains what oil is best for every engine option in the 2019 Jeep Grand Cherokee, how to pick the right product, and some practical tips that most owners overlook.
Recommended Oil Types For 2019 Jeep Grand Cherokee
Jeep offered several engines for the 2019 Grand Cherokee. Each engine requires a specific oil type and viscosity.
Using the wrong oil can cause engine wear, poor fuel economy, and even warranty issues.
3.6l Pentastar V6
The 3.6L V6 engine is the most common in the 2019 Grand Cherokee. Jeep recommends SAE 0W-20 full synthetic oil for this engine. Full synthetic oils flow better at low temperatures and protect the engine under high heat.
- Capacity: 5.9 quarts (with filter)
- Oil spec: FCA Material Standard MS-6395
5.7l Hemi V8
For the 5.7L HEMI V8, use SAE 5W-20 full synthetic oil. This oil supports the engine’s MDS (cylinder deactivation) technology and offers strong protection.
- Capacity: 7 quarts (with filter)
- Oil spec: FCA Material Standard MS-6395
6.4l Srt V8
The high-performance 6.4L SRT V8 in SRT trims requires SAE 0W-40 full synthetic oil. This oil handles high temperatures and extreme driving.
- Capacity: 7 quarts (with filter)
- Oil spec: FCA Material Standard MS-12633
6.2l Supercharged V8
The 6.2L Supercharged V8 in the Trackhawk also uses SAE 0W-40 full synthetic oil.
- Capacity: 8.3 quarts (with filter)
- Oil spec: FCA Material Standard MS-12633
3.0l Ecodiesel V6
If you have the 3.0L EcoDiesel, use SAE 5W-40 synthetic diesel oil that meets Chrysler’s MS-12991 spec.
- Capacity: 8.0 quarts (with filter)
- Oil spec: FCA Material Standard MS-12991
Oil Type Comparison
Here’s a quick comparison of oil types and capacities by engine:
| Engine | Oil Viscosity | Capacity (quarts) | Oil Spec |
|---|---|---|---|
| 3.6L V6 | 0W-20 | 5.9 | MS-6395 |
| 5.7L V8 | 5W-20 | 7 | MS-6395 |
| 6.4L V8 | 0W-40 | 7 | MS-12633 |
| 6.2L V8 | 0W-40 | 8.3 | MS-12633 |
| 3.0L Diesel | 5W-40 | 8.0 | MS-12991 |
Why Full Synthetic Oil Matters
Full synthetic oil offers several advantages for modern engines. It resists breaking down at high temperatures, reduces engine deposits, and helps maintain fuel efficiency. For the 2019 Grand Cherokee, using synthetic oil is not just a suggestion—it is a requirement for warranty and engine health.
Many drivers overlook that synthetic oil also extends the time between oil changes. While older vehicles needed oil changes every 3,000 miles, most Grand Cherokees go 7,500 10,000 miles between changes with synthetic oil.
Still, always check your owner’s manual and follow the oil life monitor.
How To Choose The Best Oil Brand
Not all oils are created equal, even if they have the right viscosity. Look for brands that meet FCA Material Standards for your engine. Some trusted options include:
- Mopar (official Jeep brand)
- Pennzoil Ultra Platinum
- Mobil 1
- Valvoline Advanced Full Synthetic
These brands are widely available and meet or exceed Jeep’s requirements.
Practical Oil Change Tips
Changing oil in a 2019 Grand Cherokee is straightforward, but a few details make a big difference:
- Always change the oil filter when you change the oil.
- Double-check the oil capacity for your engine—overfilling can cause leaks or engine damage.
- Warm up the engine before draining old oil. This helps remove more contaminants.
- Reset the oil life monitor after each oil change.
Many owners forget to use a new crush washer on the drain plug. Skipping this small part can lead to slow oil leaks.
Common Mistakes To Avoid
Two frequent mistakes are using conventional oil (instead of full synthetic) and choosing the wrong oil viscosity. Both can void your warranty. Some drivers also buy oil labeled “synthetic blend,” which is not the same as full synthetic oil. Always check that the label says “full synthetic” and matches the correct FCA oil spec.
Another overlooked detail is the oil’s API certification. Look for the “API SN” or higher badge on the bottle, which means the oil meets modern standards.
Oil Change Cost And Frequency
Expect to pay $60 $120 for an oil change at a Jeep dealer, depending on engine size and your region. Doing it yourself can cost as little as $35 $70 for quality synthetic oil and a filter.
Jeep recommends changing the oil every 7,500 10,000 miles or once a year, whichever comes first. Shorter intervals may be smart if you do a lot of towing, idling, or short trips.
Synthetic Oil Vs. Conventional Oil
Here’s a quick comparison to help you understand the difference:
| Feature | Full Synthetic | Conventional |
|---|---|---|
| Engine Protection | Excellent | Basic |
| Change Interval | 7,500–10,000 miles | 3,000–5,000 miles |
| Warranty Safe | Yes | No |
| Cost | Higher | Lower |
| Cold Starts | Superior | Average |
Frequently Asked Questions
What Happens If I Use The Wrong Oil In My 2019 Grand Cherokee?
Using the wrong oil type or viscosity can cause engine wear, poor performance, and may void your warranty. Always use the oil recommended for your engine.
Can I Use Synthetic Blend Instead Of Full Synthetic?
No. The 2019 Grand Cherokee requires full synthetic oil for all engines. Synthetic blend does not offer the same level of protection or meet manufacturer specs.
How Often Should I Check My Oil Level?
Check your oil level every month or before long trips. Engines can burn oil slowly over time, and catching a low level early prevents damage.
Are Aftermarket Oil Filters Safe To Use?
Aftermarket filters are safe if they meet or exceed OEM standards. However, Mopar filters are designed specifically for Jeep engines and provide the best fit.
Where Can I Find The Official Oil Specifications?
You can find official specs in your owner’s manual or visit the Jeep official maintenance page for more details.
Selecting the right oil for your 2019 Jeep Grand Cherokee keeps your engine running at its best and protects your investment. Always follow Jeep’s official recommendations, choose quality full synthetic oil, and stick to a regular maintenance schedule.
Small details, like using the correct oil spec and changing the crush washer, can make a big difference in your SUV’s reliability and performance.
