How Much Oil Does A 2019 Jeep Wrangler Take? A Comprehensive Guide

Understanding Your 2019 Jeep Wrangler’s Engine Options

The 2019 Jeep Wrangler (JL generation) primarily came with two distinct engine options, each with its own specific oil capacity and type requirements. Identifying which engine powers your Wrangler is the first critical step in determining its oil needs.

1. 3.6L Pentastar V6 Engine: This highly popular and proven engine is a carryover from previous Wrangler generations, known for its robust performance and reliability. It’s a naturally aspirated engine, widely recognized across many Chrysler/Jeep/Dodge vehicles.
2. 2.0L Turbo Inline-4 Engine (eTorque): Introduced as a new option with the JL generation, this turbocharged engine offers a blend of efficiency and surprising power, often paired with Jeep’s eTorque mild-hybrid system. It’s a more technologically advanced engine with different lubrication requirements.

It’s important to note that while the 3.0L EcoDiesel V6 was later introduced to the JL Wrangler lineup, it was not available for the 2019 model year. Therefore, our focus will remain on the 3.6L Pentastar V6 and the 2.0L Turbo I-4.

Oil Capacity by Engine Type: The Precise Numbers

Knowing the exact oil capacity is crucial to prevent both under-filling and over-filling, both of which can lead to significant engine issues. Always refer to your owner’s manual for the most accurate and up-to-date specifications for your specific vehicle configuration, but here are the general guidelines for the 2019 Jeep Wrangler:

• For the 3.6L Pentastar V6 Engine:

  
  • Oil Capacity: Approximately 6 US Quarts (5.7 Liters) when performing an oil and filter change.
  • Recommended Oil Type: SAE 5W-20 or 5W-30 full synthetic or synthetic blend motor oil.
  • Chrysler Specification: It is imperative that the oil meets Chrysler Material Standard MS-6395. Using oil that does not meet this specification can void your warranty and potentially harm your engine. 5W-20 is often the primary recommendation for optimal fuel economy and cold start performance, though 5W-30 may be acceptable in certain climates or for specific use cases (always check your manual).



• For the 2.0L Turbo Inline-4 Engine (eTorque):

  • Oil Capacity: Approximately 5 US Quarts (4.7 Liters) when performing an oil and filter change.
  • Recommended Oil Type: SAE 0W-20 full synthetic motor oil.
  • Chrysler Specification: This engine also requires oil that meets Chrysler Material Standard MS-6395. The lower "W" (Winter) viscosity rating (0W) is crucial for this turbocharged engine, especially for cold starts, ensuring quick lubrication to critical components. Full synthetic is typically mandated due to the higher operating temperatures and pressures associated with turbochargers.

Why Accurate Capacity Matters:

• Under-filling: Not enough oil means inadequate lubrication, leading to increased friction, overheating, premature wear on engine components, and potential catastrophic failure.
• Over-filling: Too much oil can cause the crankshaft to churn and aerate the oil, creating foam. This foam doesn’t lubricate effectively, leading to reduced oil pressure, increased wear, and potential damage to seals and gaskets due to excessive pressure. It can also cause oil to be pushed into the intake system, leading to smoke from the exhaust and catalytic converter damage.

Why the Right Oil Matters: Viscosity and Specifications

Beyond just the quantity, the quality and type of oil you use are equally important.

• Viscosity (e.g., 5W-20, 0W-20): The numbers represent the oil’s viscosity (its resistance to flow) at different temperatures. The "W" stands for "Winter." The first number (e.g., 5W, 0W) indicates the oil’s viscosity at cold temperatures, crucial for starting your engine in chilly weather and ensuring immediate lubrication. A lower number means it flows more easily when cold. The second number (e.g., 20, 30) indicates the oil’s viscosity at normal engine operating temperatures. Using the wrong viscosity can impair lubrication, especially during extreme temperatures.
• Chrysler MS-6395 Specification: This is not just a suggestion; it’s a critical standard developed by Chrysler (now Stellantis) that specifies the performance characteristics, additive packages, and overall quality required for oil to properly protect their engines. Oils meeting this standard have been rigorously tested to ensure they provide optimal protection against wear, sludge, and oxidation, specifically for the materials and designs used in their engines. Always look for this designation on the oil bottle.
• Synthetic vs. Conventional vs. Synthetic Blend:
  • Conventional Oil: Derived from crude oil, it’s the least expensive but offers the least protection and has shorter change intervals.
  • Synthetic Blend: A mix of conventional and synthetic oils, offering better protection than conventional but not as good as full synthetic.
  • Full Synthetic Oil: Engineered in a lab, full synthetic oil provides superior protection against wear, performs better in extreme temperatures (hot and cold), resists breakdown, and typically allows for longer oil change intervals. For the 2019 Jeep Wrangler, especially the 2.0L Turbo, full synthetic is either recommended or required due to the engine’s design and operating conditions. Even for the 3.6L, using full synthetic is often a wise upgrade for enhanced protection.

The Oil Change Process: A Step-by-Step Guide

Performing an oil change yourself can be a rewarding and cost-saving endeavor. If you choose to do it, ensure you have the right tools and follow safety precautions.

Materials You’ll Need:

• Correct type and quantity of engine oil (refer to capacities above).
• New oil filter (ensure it’s compatible with your specific engine).
• Oil filter wrench.
• Socket wrench and appropriate socket for the drain plug.
• Drain pan (large enough for the full oil capacity).
• Funnel.
• Rags or shop towels.
• Jack and jack stands (or ramps).
• Safety glasses and gloves.
• Torque wrench (recommended for drain plug and oil filter housing).

Steps:

1. Preparation and Safety:

   • Park your Jeep on a level surface.
   • Warm up the engine slightly (5-10 minutes) – warm oil drains more easily, but don’t make it too hot to handle.
   • Engage the parking brake.
   • Place wheel chocks behind the rear wheels.
   • Use a jack to lift the front of the vehicle and secure it with jack stands. Never rely solely on a jack.
   • Put on safety glasses and gloves.

2. Locate and Remove Drain Plug:

   • Place the drain pan directly underneath the oil pan’s drain plug.
   • Using the correct socket wrench, loosen and carefully remove the drain plug. Be prepared for oil to flow out immediately.
   • Allow all the old oil to drain completely. This can take 10-15 minutes.

3. Replace Oil Filter:

   • Once the oil flow slows to a drip, move the drain pan under the oil filter.
   • Use an oil filter wrench to loosen the old filter. Be aware that more oil will spill out as you remove it.
   • Once removed, clean the filter mounting surface on the engine.
   • Apply a thin film of new oil to the rubber gasket of the new oil filter.
   • Screw on the new filter by hand until it’s snug, then tighten it according to the filter manufacturer’s instructions (usually an additional 1/2 to 3/4 turn, or use a torque wrench to specifications, typically 18-20 ft-lbs).

4. Reinstall Drain Plug:

   • Once the oil has finished draining, clean the drain plug and the area around the drain hole.
   • Replace the drain plug’s crush washer (if applicable) or O-ring with a new one to ensure a leak-proof seal.
   • Reinstall the drain plug and tighten it to the manufacturer’s specified torque (typically 20-25 ft-lbs for the 3.6L, check your manual). Do not overtighten, as this can strip the oil pan threads.

5. Add New Oil:

   • Lower the vehicle safely off the jack stands.
   • Locate the oil filler cap on top of the engine.
   • Place a funnel in the oil filler neck.
   • Slowly pour in the recommended amount of new oil for your engine (6 quarts for 3.6L, 5 quarts for 2.0L Turbo).
   • Wait a few minutes for the oil to settle.

6. Check Oil Level:

   • Remove the dipstick, wipe it clean, reinsert it fully, then remove it again.
   • The oil level should be between the "MIN" and "MAX" marks on the dipstick. Add small amounts of oil if needed, rechecking after each addition. Do not overfill.

7. Final Checks and Disposal:

   • Start the engine and let it run for a minute or two to circulate the new oil. Check for any leaks around the drain plug and oil filter.
   • Turn off the engine, wait a few minutes for the oil to settle, and recheck the dipstick one last time.
   • Properly dispose of the old oil and filter at a certified recycling center or auto parts store. Never pour used oil down the drain or into the ground.

8. Reset Oil Change Indicator: Your 2019 Jeep Wrangler has an oil change indicator system. After an oil change, you’ll need to reset it. The procedure typically involves turning the ignition to the "ON/RUN" position (without starting the engine), fully depressing the accelerator pedal three times within 10 seconds, then turning the ignition to the "OFF" position. Consult your owner’s manual for the exact steps for your model.

Oil Change Frequency and Monitoring

Jeep recommends following the oil change indicator system in your 2019 Wrangler. This system monitors various factors, including engine revolutions, operating temperature, and driving conditions, to determine the optimal oil change interval. Generally, this can range from 7,500 to 10,000 miles or 12 months, whichever comes first, for normal driving conditions with synthetic oil.

However, certain factors can necessitate more frequent oil changes:

• Severe Driving Conditions: Frequent short trips, extensive idling, towing, heavy loads, dusty environments, or extreme temperatures.
• Off-Roading: Heavy off-road use puts extra strain on the engine and can accelerate oil degradation.
• Frequent Stop-and-Go Traffic: Contributes to higher engine temperatures and more wear.

How to Check Your Oil Level:
It’s good practice to check your oil level regularly, perhaps once a month or before a long trip.

1. Park on level ground.
2. Ensure the engine is off and has cooled down for at least 10-15 minutes (or longer for a cold check).
3. Locate the yellow-handled dipstick (typically on the passenger side for the 3.6L, driver side for the 2.0L).
4. Pull it out, wipe it clean with a rag.
5. Reinsert it fully until it seats.
6. Pull it out again and observe the oil level between the "MIN" and "MAX" marks. If it’s below "MIN," add oil slowly, rechecking frequently.

Common Challenges and Solutions

• Stripped Drain Plug or Oil Pan: Overtightening is a common culprit. Always use a torque wrench and the correct specifications. If stripped, you may need a larger drain plug (oversized) or, in severe cases, oil pan replacement.
• Oil Leaks: After an oil change, check for leaks around the drain plug and oil filter. Ensure the drain plug is tightened correctly with a new crush washer, and the oil filter is snug but not overtightened.
• Using the Wrong Oil: Always double-check the viscosity and the MS-6395 specification. Using incorrect oil can lead to poor lubrication, engine wear, and potential warranty issues. If you accidentally use the wrong type, it’s best to drain it and refill with the correct oil.
• Disposing of Used Oil: Never pour it down the drain. Most auto parts stores, quick lube centers, and municipal waste facilities accept used motor oil for recycling.

Practical Tips for Jeep Owners

• Always Consult Your Owner’s Manual: This is your primary source for all specifications, procedures, and maintenance schedules specific to your 2019 Jeep Wrangler.
• Use Quality Oil Filters: Don’t skimp on the oil filter. A high-quality filter ensures proper filtration, protecting your engine from contaminants. Mopar OEM filters are always a safe bet, but reputable aftermarket brands are also available.
• Consider Full Synthetic Oil: Even if your 3.6L V6 technically allows for synthetic blend (meeting MS-6395), using full synthetic offers superior protection, especially for a vehicle that might see demanding conditions like a Wrangler. For the 2.0L Turbo, full synthetic is mandatory.
• Keep Records: Maintain a log of your oil changes, including the date, mileage, type of oil used, and filter installed. This is helpful for warranty purposes and tracking your vehicle’s maintenance history.
• Listen to Your Engine: Unusual noises, a drop in performance, or the illumination of the check engine light could all be signs of an oil-related issue. Address them promptly.
