If you own a 2017 Jeep Grand Cherokee, choosing the right oil is one of the most important things you can do for your SUV’s health. Using the correct oil type keeps your engine running smoothly, improves fuel economy, and helps prevent costly repairs.
Many drivers feel confused about oil grades, brands, and how often to change the oil.
This guide clears up those details, so you can take care of your Grand Cherokee with confidence.
Recommended Oil Types For 2017 Jeep Grand Cherokee
The 2017 Jeep Grand Cherokee comes with several engine options. Each engine has its recommended oil type. Using the correct oil is important because it matches your engine’s needs for temperature, performance, and longevity.
Engine Options And Oil Specifications
Here’s a breakdown of the main 2017 Grand Cherokee engines and their recommended oil:
- 3.6L Pentastar V6
- Oil Type: SAE 0W-20
- Oil Capacity: 5.9 quarts (with filter)
- 5.7L HEMI V8
- Oil Type: SAE 5W-20
- Oil Capacity: 7.0 quarts (with filter)
- 6.4L SRT HEMI V8
- Oil Type: SAE 0W-40 (Full synthetic recommended)
- Oil Capacity: 7.0 quarts (with filter)
- 3.0L EcoDiesel V6
- Oil Type: SAE 5W-40 (Synthetic)

Why Oil Type Matters
Each oil grade (such as 0W-20 or 5W-20) describes how the oil flows at cold and hot temperatures. For example, 0W-20 is thinner when cold, which helps engines start easily in winter and provides better protection as the engine heats up. Using the wrong grade can reduce efficiency and even void warranties.
Synthetic Vs Conventional Oil: Which Should You Choose?
Most modern engines, including those in the 2017 Grand Cherokee, benefit from synthetic oil. Here’s a quick comparison:
| Type | Benefits | Drawbacks |
|---|---|---|
| Synthetic | Better protection, longer intervals, high/low temp stability | Higher cost |
| Conventional | Lower cost, good for older engines | Shorter change intervals, less protection |
Synthetic oil is usually the best choice for Grand Cherokee engines, especially if you want better protection and less frequent oil changes.
How Often Should You Change The Oil?
Oil change intervals depend on your engine, oil type, and driving habits.
- For most 2017 Grand Cherokees using synthetic oil, change every 8,000–10,000 miles or once a year.
- If you do a lot of short trips, towing, or drive in extreme conditions, change oil more often—every 5,000–7,500 miles.
Your vehicle’s oil life monitor is a smart tool. It tracks how you drive and tells you when it’s time for service. Always check your owner’s manual for the most accurate advice.
What Happens If You Use The Wrong Oil?
Many drivers think all oils are the same, but they’re not. Using the wrong oil grade (for example, 5W-30 instead of 0W-20) can lead to:
- Engine knocking
- Reduced fuel economy
- Increased wear and tear
- Possible engine damage
If you’re still under warranty, using the wrong oil could even void your coverage. Always double-check before adding new oil.
How To Check And Top Off Oil In Your Grand Cherokee
Checking your oil level regularly keeps your engine protected. Here’s how:
- Park on a level surface and let the engine cool for 10 minutes.
- Pull out the dipstick, wipe it clean, and re-insert it fully.
- Remove the dipstick again and check the oil level. It should be between the “min” and “max” marks.
- If low, add oil slowly—never overfill. Use a funnel to avoid spills.
Here’s a quick reference chart for top-up amounts:
| Engine | Amount (if low) | Oil Type |
|---|---|---|
| 3.6L V6 | 1/2 quart at a time | 0W-20 |
| 5.7L V8 | 1/2 quart at a time | 5W-20 |
| 6.4L V8 | 1/2 quart at a time | 0W-40 |
| 3.0L Diesel | 1/2 quart at a time | 5W-40 |
Common Oil Change Mistakes
Even experienced drivers make simple oil mistakes. Here are two that many beginners miss:
1. Not Replacing The Oil Filter:
Changing the oil but not the filter leaves old debris in your engine. Always replace both.
2. Mixing Oil Brands Or Types:
Mixing oils can change the chemical balance. Stick with one type and brand whenever possible.
Another error is not tightening the oil drain plug enough, which can lead to leaks and engine damage.

Signs You Need An Oil Change
Sometimes, your oil change light may not come on right away. Look for these signs:
- Engine is noisier than usual
- Oil looks dark or dirty on the dipstick
- You smell oil inside the car
- Oil level drops quickly between changes
Don’t ignore these signs. Quick action can prevent expensive engine problems.
