The right oil is vital for keeping your 2017 Jeep Wrangler running smoothly. Using the proper oil helps the engine stay clean, reduces wear, and protects your Jeep against tough driving conditions.
But with so many oils on the shelf, it’s easy to get confused.
This guide breaks down what oil your 2017 Jeep Wrangler needs, why it matters, and how to make the best choice for your engine’s health.
Recommended Oil Type For 2017 Jeep Wrangler
Jeep recommends SAE 5W-20 engine oil for the 2017 Wrangler. This applies to both the 3.6L V6 engine and the less common 2.8L diesel found in some export models. The “5W” refers to the oil’s flow at cold temperatures, and “20” means it remains thin enough at engine temperature.
If you drive in extreme conditions—like very hot or cold climates—Jeep allows for some flexibility, but always check your owner’s manual for your specific model.
Synthetic Vs Conventional Oil
Most Jeep owners wonder if they should use synthetic or conventional oil. While conventional oil meets basic requirements, full synthetic oil offers extra benefits:
- Better protection at high and low temperatures
- Improved engine cleanliness
- Longer oil change intervals
A synthetic blend is also acceptable and costs less than full synthetic. However, for the best performance and protection, especially if you take your Wrangler off-road, synthetic is worth the small extra cost.
Quick Comparison
| Oil Type | Protection Level | Oil Change Interval | Cost |
|---|---|---|---|
| Full Synthetic | Best | 5,000-7,500 miles | High |
| Synthetic Blend | Better | 4,000-6,000 miles | Medium |
| Conventional | Good | 3,000-5,000 miles | Low |
How Much Oil Does A 2017 Jeep Wrangler Need?
The 3.6L V6 Pentastar engine uses about 6 quarts (5.7 liters) of oil with a filter change. Always check the dipstick after refilling to make sure you’re within the safe range.
If you have the rare 2.8L diesel engine, it uses around 8.5 quarts (8 liters).
Oil Brands And Certifications
Not all oils are created equal. Always look for oils that meet Chrysler MS-6395 specifications. This ensures the oil works well with your Jeep’s engine design.
Some trusted brands include:
- Mopar
- Pennzoil
- Mobil 1
- Valvoline
- Castrol
Buying a cheaper, uncertified oil may seem like a good deal, but it could lead to engine damage and void your warranty.
Changing Oil: When And Why It Matters
Changing your oil on time is as important as the oil you use. For the 2017 Wrangler, the standard interval is every 5,000 to 7,500 miles if you use synthetic oil. If you drive in dusty, hot, or very cold places, or often tow heavy loads, change it more often—around every 4,000 miles.
Many new Jeeps have an oil life monitor that tells you when it’s time for a change. Don’t ignore it—old oil breaks down and can’t protect your engine.
Step-by-step: How To Change Your 2017 Jeep Wrangler’s Oil
- Gather Supplies: 6 quarts of 5W-20 oil, new oil filter, wrench, drain pan.
- Warm Up the Engine: Run for a few minutes to thin the oil.
- Lift the Vehicle Safely: Use ramps or a jack and stands.
- Drain Old Oil: Remove the drain plug, let oil flow into pan.
- Replace Oil Filter: Use a filter wrench. Lube the new filter’s rubber gasket.
- Refill with New Oil: Pour in 6 quarts, replace the cap.
- Check the Level: After a minute, check with the dipstick. Top off if needed.
- Dispose of Old Oil Properly: Take used oil to a recycling center.
Some owners forget to change the oil filter with every oil change. Skipping the filter can shorten engine life and reduce oil quality.
Real-world Example: Off-road Driving
If you take your Wrangler off-road, your oil faces extra heat, dust, and heavy loads. Synthetic oil is especially helpful here because it resists breaking down under stress.
A Wrangler owner who enjoys rock-crawling in Arizona switched to full synthetic oil and noticed smoother idling and less frequent oil changes, especially after hard trips. This small upgrade can bring peace of mind on the trail.
Common Mistakes To Avoid
- Using the wrong oil viscosity (example: 10W-40) can hurt fuel efficiency and engine performance.
- Overfilling or underfilling oil can cause leaks or damage.
- Choosing the cheapest oil without checking for Chrysler MS-6395 approval.
- Skipping oil changes when the oil still “looks clean” to the eye—oil can lose protection even if it’s not dark.
Oil For Different Climates
If you live in a cold climate, 5W-20 oil flows well at freezing temperatures, helping your engine start easier. In very hot climates, stick with 5W-20 unless your manual suggests a different grade for extreme heat.
For example, in Alaska’s winter, a Jeep owner might see smoother starts and less engine noise with the recommended oil, compared to a heavier grade.
Cost Of An Oil Change
A DIY oil change with synthetic oil and a filter costs around $40–$60. At a dealer or shop, expect to pay $60–$100. Full synthetic oil raises the price, but also extends oil change intervals, which can save money over time.

Frequently Asked Questions
What If I Accidentally Use The Wrong Oil In My 2017 Jeep Wrangler?
If you use oil with the wrong viscosity or without the right certification, change it as soon as possible. Using the wrong oil once may not cause instant damage, but repeated use can lead to engine problems.

Yes, you can switch anytime. Synthetic oil mixes safely with conventional oil.
After switching, you may notice smoother starts and longer oil life.
Is Mopar Oil Better For My Wrangler?
Mopar oil is made to meet Jeep’s standards but isn’t the only good choice. Any brand with Chrysler MS-6395 approval will work well.
