Finding the right oil for your 2014 Jeep Grand Cherokee is not just about following the manual it’s about protecting your engine and saving money in the long run.
Many drivers make quick choices at the auto parts store, but a little research ensures better performance, fewer repairs, and a longer vehicle life.
Let’s break down what oil is best for your Grand Cherokee, why it matters, and how to make the right decision for your specific model and driving style.
Understanding Oil Needs For The 2014 Jeep Grand Cherokee
Jeep’s 2014 Grand Cherokee lineup comes with several engine options, and each has its own oil requirements. Picking the correct oil type keeps the engine running smoothly and avoids possible damage.
Engine Types And Their Oil Specifications
The 2014 Grand Cherokee was available with these engines:
- 3.6L V6
- 5.7L V8 HEMI
- 6.4L SRT V8
- 3.0L EcoDiesel V6
Each engine needs a specific oil viscosity and specification. Using the wrong oil can reduce fuel efficiency or even void your warranty.
Recommended Oil Types By Engine
Here’s a breakdown of which oil to use for each engine. This information is based on Jeep’s official recommendations and trusted auto experts.
| Engine | Recommended Oil | Viscosity | Capacity (with filter) |
|---|---|---|---|
| 3.6L V6 | Synthetic | SAE 5W-20 | 6 quarts |
| 5.7L V8 HEMI | Synthetic | SAE 5W-20 | 7 quarts |
| 6.4L SRT V8 | Synthetic | SAE 0W-40 | 7 quarts |
| 3.0L EcoDiesel V6 | Synthetic Diesel Oil | SAE 5W-40 | 8.1 quarts |
Synthetic oil is recommended for all engines. It performs better in extreme temperatures, reduces engine wear, and keeps the engine cleaner.
Why Oil Viscosity And Type Matter
Oil viscosity—like 5W-20 or 0W-40—shows how the oil flows at different temperatures. The first number (“5W”) measures flow when cold, while the second (“20” or “40”) shows thickness at engine operating temperature.
- Thinner oil (lower numbers) flows easily during cold starts, protecting engine parts.
- Thicker oil (higher numbers) provides extra protection under high heat or heavy loads.
Using the correct viscosity helps prevent engine sludge, overheating, or poor fuel economy. For example, the SRT model’s high-performance engine needs 0W-40 for better protection at high speeds.
Conventional Vs. Synthetic Oil
You might wonder if you can use regular oil instead of synthetic. For the 2014 Grand Cherokee, synthetic oil is the best choice for all engines. Here’s why:
| Oil Type | Benefits | Drawbacks |
|---|---|---|
| Synthetic | Better engine protection, longer oil life, handles extreme temperatures well | More expensive |
| Conventional | Cheaper, easy to find | Breaks down faster, less protection, not recommended by Jeep |
Jeep’s own manuals and major oil brands like Mobil 1 and Pennzoil agree: synthetic is the way to go.
Oil Change Interval And Maintenance Tips
Changing oil on time is just as important as using the right kind. Jeep recommends oil changes every 8,000 miles or 6 months, whichever comes first, for most 2014 Grand Cherokee models using synthetic oil. If you drive in harsh conditions (towing, very hot or cold weather, dusty roads), change it sooner—about every 5,000 miles.
Some practical tips:
- Always replace the oil filter when you change your oil.
- Check oil levels monthly, especially before long trips.
- Use high-quality oil that meets Chrysler MS-6395 (for gasoline engines) or MS-11106 (for EcoDiesel).
A common mistake is topping up with the wrong oil type or mixing brands. Stick to one oil specification for best results.
How To Choose The Right Oil Brand
All major oil brands sell the recommended types for your Jeep. Look for these features:
- API Certification – The oil should display the “API Starburst” symbol for gasoline engines or “API Diesel” for diesel engines.
- Chrysler Approval – The bottle should mention MS-6395 or MS-11106.
- Full Synthetic – Avoid blends or conventional unless you have no other choice in an emergency.
Popular brands for the 2014 Jeep Grand Cherokee include Mobil 1, Pennzoil Ultra Platinum, and Valvoline Advanced Full Synthetic.
What Happens If You Use The Wrong Oil?
Using the wrong oil can cause:
- Engine knocking or noisy operation
- Reduced fuel efficiency
- Faster engine wear
- Possible warranty issues
For diesel engines, using non-diesel oil can even damage the emission system. Always double-check the bottle before pouring.
Real-world Example: Owner Experience
A 2014 Grand Cherokee owner shared that after switching from conventional to synthetic 5W-20, the engine ran quieter and fuel economy improved by about 1-2 mpg. Another owner with the EcoDiesel model noted fewer issues with the emission system after following Jeep’s MS-11106 synthetic diesel recommendation.
Frequently Asked Questions
What Oil Does The 3.6l V6 Grand Cherokee Need?
The 3.6L V6 engine requires SAE 5W-20 full synthetic oil. It’s important to use oil that meets Chrysler MS-6395 for best protection.
Can I Use 5w-30 Oil Instead Of 5w-20?
No, 5W-30 is not recommended for any 2014 Grand Cherokee engine. Using a different viscosity can harm performance and may void your warranty.
How Often Should I Change The Oil In My 2014 Grand Cherokee?
With synthetic oil, change every 8,000 miles or 6 months. If you drive in tough conditions, every 5,000 miles is safer.
What Oil Does The 3.0l Ecodiesel Use?
The 3.0L EcoDiesel V6 requires SAE 5W-40 full synthetic diesel oil that meets Chrysler MS-11106.
Where Can I Find The Official Oil Specifications?
You can check your owner’s manual or visit the official Mopar site for the latest Jeep oil standards.
Choosing the right oil for your 2014 Jeep Grand Cherokee is a small step that makes a big difference. Stick to Jeep’s recommendations, use high-quality synthetic oil, and you’ll keep your SUV running strong for years.
