Understanding Your 2017 Jeep Wrangler Unlimited’s Engine

The 2017 Jeep Wrangler Unlimited (JK generation) is predominantly powered by the robust 3.6-liter Pentastar V6 engine. This engine, renowned for its balance of power, efficiency, and reliability, is a staple across many Chrysler, Dodge, and Jeep vehicles. Its design incorporates advanced features like variable valve timing, which demands precise lubrication to function correctly. The engine’s size and internal components directly dictate the specific oil capacity and viscosity required to maintain optimal operating temperatures and reduce friction effectively.

The Crucial Question: How Much Oil Does A 2017 Jeep Wrangler Unlimited Take?

For the 2017 Jeep Wrangler Unlimited equipped with the 3.6L Pentastar V6 engine, the answer is straightforward: it takes 6 quarts (or approximately 5.7 liters) of engine oil when performing an oil and filter change.

It is absolutely crucial to always change the oil filter every time you change the engine oil. The filter traps contaminants and debris, and installing a new filter ensures that the fresh oil remains clean and effective from the start, providing maximum protection to your engine.

Recommended Oil Type and Viscosity for Your Wrangler

Beyond just the quantity, the type and viscosity of oil are equally vital. For the 3.6L Pentastar V6 engine in your 2017 Jeep Wrangler Unlimited, the manufacturer (FCA/Stellantis) strongly recommends the following:

• Viscosity: SAE 5W-20. This weight is specifically formulated to provide optimal lubrication across a wide range of operating temperatures, ensuring easy cold starts and robust protection when the engine is hot.
• Type: Full Synthetic Oil is highly recommended. While some older vehicles might do well with conventional or synthetic blends, modern engines like the Pentastar V6 benefit immensely from the superior protection, stability, and longevity offered by full synthetic oil. Synthetic oils are engineered to withstand higher temperatures, resist breakdown, and provide better sludge prevention, which is crucial for engines with tighter tolerances and advanced components.
• Certification: Look for oils that meet or exceed the API (American Petroleum Institute) SN, SP, or a newer specification. More importantly, ensure the oil meets Chrysler’s specific material standard MS-6395. This certification guarantees the oil has passed rigorous tests set by the manufacturer to ensure compatibility and performance with your engine’s design.

Using an oil that does not meet the MS-6395 specification, even if it’s the correct viscosity, can potentially lead to premature engine wear or issues not covered under warranty. Always check the oil bottle for these specific markings.

Why the Right Oil Capacity and Type Matter: Critical Considerations

Understanding the "why" behind these specifications reinforces their importance:

• Underfilling (Too Little Oil): If your engine has insufficient oil, critical components will not receive adequate lubrication. This leads to increased friction, excessive heat buildup, accelerated wear, and potential catastrophic engine failure. Low oil levels can also cause the oil pump to suck air, leading to a loss of oil pressure and further damage.
• Overfilling (Too Much Oil): While seemingly less harmful, overfilling can be equally detrimental. Excess oil can be whipped into a froth by the crankshaft, leading to aeration. Aerated oil is less effective at lubricating and dissipating heat. It can also increase crankcase pressure, potentially blowing out seals (like crankshaft seals), leading to costly leaks. Furthermore, excess oil can be forced into the PCV (Positive Crankcase Ventilation) system, leading to oil consumption, deposits on spark plugs, and even damage to the catalytic converter.



• Incorrect Viscosity: Using oil that is too thick (e.g., 10W-30 instead of 5W-20) can make cold starts harder, reduce fuel economy, and potentially starve critical components of lubrication, especially when cold. Oil that is too thin (e.g., 0W-10) might not provide adequate protection at high operating temperatures, leading to metal-on-metal contact and wear.
• Incorrect Type (e.g., Conventional vs. Synthetic): Modern engines like the Pentastar V6 are designed with tighter tolerances and often run hotter than older engines. Synthetic oil’s superior thermal stability and lubricating properties are essential for these designs. Using conventional oil where synthetic is recommended can lead to faster oil breakdown, sludge formation, and reduced engine longevity.

Step-by-Step: Changing the Oil in Your 2017 Jeep Wrangler Unlimited (DIY Guide)

Performing an oil change yourself can save money and provide a deeper understanding of your vehicle.

Tools and Materials You’ll Need:

• New oil filter (Mopar recommended, or equivalent quality)
• Oil filter wrench
• Socket wrench and appropriate socket for the drain plug (usually 13mm)
• Oil drain pan (capacity of at least 7-8 quarts)
• Funnel
• Jack and jack stands, or automotive ramps
• Gloves and safety glasses
• Shop rags or paper towels
• Torque wrench (optional, but recommended for drain plug)

Procedure:

1. Preparation: Park your Wrangler on a level surface. For better access, you might need to lift the front end using ramps or a jack and jack stands. If using a jack, ensure the vehicle is stable on jack stands before getting underneath.
2. Warm Up Engine (Slightly): Run the engine for a few minutes to warm the oil. Warm oil drains more easily. Do NOT let it get too hot to avoid burns.
3. Locate Drain Plug: The oil drain plug is located at the bottom of the oil pan, typically towards the front of the engine, usually on the driver’s side. Place your drain pan directly underneath.
4. Drain Oil: Using your socket wrench, carefully loosen and remove the drain plug. Be prepared for the hot oil to flow out quickly. Allow all the oil to drain completely (this can take 10-15 minutes).
5. Replace Drain Plug: Once drained, clean the drain plug and the area around the oil pan. Reinstall the drain plug, ensuring it’s snug. If using a torque wrench, tighten to the manufacturer’s specified torque (consult your owner’s manual; typically around 20-25 ft-lbs). Do not overtighten!
6. Locate and Remove Oil Filter: On the 3.6L Pentastar V6, the oil filter is a cartridge type, located on top of the engine, near the front, usually under a plastic cap. Use your oil filter wrench to unscrew the cap. Carefully pull out the old filter element. There might be some residual oil, so have rags ready.
7. Install New Oil Filter: Lubricate the new O-rings (usually provided with the new filter) with a little fresh oil. Insert the new filter element into the housing, ensuring it seats correctly. Screw the cap back on by hand until snug, then use the wrench to tighten it according to manufacturer specifications (often marked on the cap, usually around 18 ft-lbs).
8. Add New Oil: Remove the oil filler cap (usually marked with an oil can symbol) on top of the engine. Place your funnel in the opening and slowly pour in 5 quarts of the recommended 5W-20 full synthetic oil.
9. Check Oil Level: Wait a few minutes for the oil to settle. Pull out the dipstick, wipe it clean, reinsert it fully, then pull it out again. Check the oil level. It should be within the "safe" range.
10. Top Off: Add the remaining 1 quart of oil gradually, checking the dipstick frequently, until the level is at the "full" mark. Do not overfill.
11. Start Engine and Check for Leaks: Start the engine and let it run for a minute or two. Check underneath for any leaks around the drain plug or oil filter.
12. Final Oil Level Check: Turn off the engine, wait 5-10 minutes for the oil to settle, and check the dipstick one last time. Adjust if necessary.
13. Reset Oil Change Indicator: This is crucial. Consult your owner’s manual for the exact procedure, but typically it involves turning the ignition to "RUN" (without starting the engine), pressing the accelerator pedal to the floor three times within 10 seconds, then turning the ignition off. The "Oil Change Due" light should reset.
14. Dispose of Old Oil: Properly dispose of the used oil at a local auto parts store, service station, or recycling center. Never pour it down drains or onto the ground.
