The correct oil type for a 2014 Jeep Grand Cherokee Limited depends entirely on the engine option installed in the vehicle. For the 3.6L Pentastar V6 engine, the correct oil type is SAE 5W-20 meeting Chrysler Material Standard MS-6395. For the 5.7L HEMI V8 engine, the factory recommendation is SAE 5W-20 (also meeting MS-6395), though some older documentation or heavy-duty use cases historically referenced 5W-30 (always verify the oil filler cap). For the 3.0L V6 EcoDiesel engine, the required oil type is SAE 5W-30 meeting Fiat Chrysler Automobiles (FCA) Material Standard MS-11106, specifically formulated for diesel particulate filter compatibility.
Understanding the specific lubrication requirements of your 2014 Jeep Grand Cherokee Limited is essential for preserving engine longevity, optimizing fuel economy, and maintaining emissions compliance. Because this model year was offered with multiple powertrain configurations, owners cannot rely on a single catch-all fluid specification. Using the wrong viscosity grade or an oil that lacks the proper manufacturer certification can lead to premature mechanical wear, variable valve timing (VVT) complications, or damage to costly emissions control systems like the diesel particulate filter (DPF).
This comprehensive guide examines every factory-approved oil type, viscosity grade, fluid capacity, change interval, and maintenance best practice for the 2014 Jeep Grand Cherokee Limited across its available engine options.
Understanding Engine Options in the 2014 Jeep Grand Cherokee Limited
The "Limited" trim level sits comfortably in the middle-to-high tier of the Jeep Grand Cherokee lineup, bridging everyday comfort with robust capability. For the 2014 model year, Jeep offered three distinct engine configurations for the Limited trim. Identifying your specific engine is the critical first step before purchasing oil or filters.
1. The 3.6L Pentastar V6 Engine
The 3.6-liter Pentastar V6 is the most common engine found in the 2014 Jeep Grand Cherokee Limited. Known for its aluminum block and DOHC architecture, this engine relies heavily on precise hydraulic pressure to actuate its Variable Valve Timing (VVT) system.
- Primary Oil Viscosity: SAE 5W-20
- Manufacturer Specification: Chrysler MS-6395
- Capacity (with filter): 6.0 quarts (5.7 liters)
2. The 5.7L HEMI V8 Engine
For drivers requiring higher towing capacities and immediate low-end torque, the 5.7-liter HEMI V8 was available as an upgrade. This pushrod engine features Multi-Displacement System (MDS) technology, which deactivates four cylinders under light-load cruising conditions to save fuel. The MDS solenoids and lifters are exceptionally sensitive to oil cleanliness and correct viscosity.
- Primary Oil Viscosity: SAE 5W-20
- Manufacturer Specification: Chrysler MS-6395
- Capacity (with filter): 7.0 quarts (6.6 liters)
3. The 3.0L V6 EcoDiesel Engine
Introduced for the 2014 model year, the 3.0-liter EcoDiesel V6 (sourced from VM Motori) offers exceptional highway cruising range and torque. Diesel engines operate under completely different combustion dynamics than gasoline engines, generating higher soot loads and requiring specialized low-ash oils to protect the emissions equipment.
- Primary Oil Viscosity: SAE 5W-30
- Manufacturer Specification: FCA MS-11106 (or ACEA C3 / API CJ-4 depending on exact sub-specifications and regional manuals)
- Capacity (with filter): 8.0 quarts (7.5 liters)
Detailed Oil Specifications and Standards
Selecting an oil based solely on the number on the bottle (such as 5W-20) is insufficient for modern vehicles. Automakers like Chrysler (now Stellantis) design their engines with specific tolerances, bearing clearances, and metallurgical compositions that require proprietary additive packages.
Why Chrysler Material Standard MS-6395 Matters
For both the 3.6L V6 and 5.7L V8 gasoline engines, the owner's manual explicitly mandates oils that meet Chrysler Material Standard MS-6395. This standard goes beyond standard API (American Petroleum Institute) ratings.
MS-6395 certification ensures that the oil provides adequate protection against:
- Low-Speed Pre-Ignition (LSPI): Preventing destructive combustion anomalies in modern direct-injection or high-compression environments.
- Sludge Formation: Guarding against varnish and carbon deposits on critical internal components, particularly around tight hydraulic valve train passages.
- Chain Wear: Protecting timing chains from premature elongation, which is vital for the 3.6L Pentastar engine.
Synthetic vs. Conventional Oil
While traditional conventional oils were once standard, Jeep specifies synthetic-blend or full-synthetic oils to meet MS-6395 and MS-11106 standards.
- Gasoline Engines (3.6L & 5.7L): Full synthetic or high-quality synthetic blend oils in 5W-20 are strongly recommended. Full synthetic oils maintain their viscosity more consistently across extreme temperature swings, flowing more readily during winter startups and resisting thermal breakdown during heavy towing in summer heat.
- Diesel Engine (3.0L): Requires specialized synthetic diesel engine oil. Standard gasoline engine oils must never be used in the EcoDiesel, as they lack the chemical additives needed to prevent rapid contamination and clogging of the diesel particulate filter (DPF).

| 3.0L EcoDiesel V6 | SAE 5W-30 | FCA MS-11106 | 8.0 Quarts (7.5 Liters) | Up to 10,000 miles* |
*Note: Maximum interval limits assume ideal operating conditions. Severe driving conditions necessitate more frequent changes.
Oil Change Intervals and Severe Duty Conditions
The 2014 Jeep Grand Cherokee Limited is equipped with an Oil Change Indicator System. This dashboard-integrated algorithm calculates oil life based on engine operating hours, ambient temperatures, trip lengths, and driving habits. Under optimal conditions, the system may trigger a service light up to 10,000 miles or 12 months, whichever comes first.
However, many owners operate their vehicles under Severe Duty Conditions, which require shortening the oil change interval to every 4,000 to 5,000 miles.
What Constitutes Severe Driving?
- Frequent short trips of less than 10 miles (16 km) where the engine fails to reach full operating temperature.
- Frequent driving in dusty or sandy environments.
- Extensive idling or continuous stop-and-go urban traffic.
- Trailer towing, snowplowing, or regular operation in mountainous terrain.
- Ambient operation in temperatures consistently below freezing or excessively high heat.
Failing to shorten the oil change interval during severe service accelerates additive depletion, leading to increased engine wear and potential sludge accumulation.
Step-by-Step Oil Change Procedure for the 2014 Jeep Grand Cherokee Limited
Performing your own oil change on a 2014 Jeep Grand Cherokee Limited is straightforward, though specific engine layouts present unique access considerations.
Tools and Supplies Needed
- Correct quantity and viscosity of certified engine oil (6 quarts for V6, 7 quarts for V8, 8 quarts for Diesel).
- Replacement oil filter (Cartridge style for V6/Diesel, spin-on style for V8).
- Oil filter wrench (particularly useful for the V8 spin-on filter or the V6 housing cap).
- Drain pan and funnel.
- Socket set (typically 13mm or 15mm for the oil pan drain plug, depending on the engine/pan).
- Torque wrench.
- Clean shop rags and fresh rubber gloves.
- Safety glasses and vehicle ramps or a hydraulic jack with sturdy jack stands.
Step 1: Warm and Elevate the Engine
Run the engine for 3 to 5 minutes to warm the oil, making it less viscous so it drains more completely and suspends contaminants. Shut off the engine, engage the parking brake, and safely elevate the front of the vehicle using approved ramps or hydraulic jacks paired with jack stands. Never crawl under a vehicle supported only by a hydraulic jack.
Step 2: Drain the Old Oil
Locate the oil drain plug on the bottom of the oil pan. Position your drain pan underneath the plug. Carefully loosen the plug with your socket wrench, then spin it out by hand while pulling it away quickly to avoid getting hot oil on your fingers. Allow the oil to drain completely into the pan. Inspect the drain plug gasket or O-ring for crushing or cracking, replacing it if necessary. Reinstall the plug and torque it to factory specifications (do not overtighten, as aluminum oil pans can easily strip).
Step 3: Replace the Oil Filter
- For the 3.6L V6 and 3.0L EcoDiesel: These engines use a top-mounted or bottom-mounted cartridge filter inside a plastic housing. Unscrew the housing cap, pull out the old filter element, and discard the old O-rings. Clean the housing cap, install the new O-ring lubricated with fresh oil, snap the new filter element into place, and torque the housing cap to the specification printed on the cap (usually 25 Nm).
- For the 5.7L HEMI V8: This engine uses a traditional spin-on filter located on the underside of the engine. Use a filter wrench to loosen it, catch any residual oil in your drain pan, and spin it off. Wipe the mounting base clean with a rag. Dip a clean finger in fresh oil and smear a light film onto the rubber gasket of the new filter. Screw the new filter on by hand until it seats snugly, then turn it an additional three-quarters to one full turn. Do not use a wrench to tighten the new filter.
Step 4: Refill with Fresh Oil
Remove the oil filler cap located on the valve cover. Insert a clean funnel and pour in the exact recommended volume of oil. Pause briefly before adding the final quart to account for any residual oil left in the engine. Reinstall the oil filler cap securely.
Step 5: Check Levels and Reset the Indicator
Start the engine and let it idle for 30 seconds while checking underneath for any leaks around the drain plug and filter housing. Shut the engine off, wait a few minutes for the oil to settle back into the pan, pull the dipstick, wipe it, reinsert it, and check that the level falls within the operating range.
Finally, reset the oil change indicator on your instrument cluster:
- Turn the ignition switch to the ON position (do not start the engine).
- Use the steering wheel directional pad to navigate to the Vehicle Info screen, then select Oil Life.
- Press and hold the OK button on the steering wheel until the percentage resets to 100%.
Common Mistakes to Avoid
- Using Non-Certified Oils: Pouring generic over-the-counter oil that lacks the MS-6395 certification into a gasoline engine can jeopardize warranty claims and lead to mechanical issues over time.
- Overtightening Filter Housings: The plastic filter caps on the 3.6L V6 require precise torque. Overtightening them with breaker bars will crack the plastic housing, resulting in catastrophic oil leaks.
- Ignoring EcoDiesel Specifics: Using standard 5W-40 or 5W-30 gasoline engine oil in the 3.0L EcoDiesel will quickly foul the emissions system and damage the diesel particulate filter.
- Failing to Replace Crush Washers: Reusing a worn drain plug washer can cause a slow, persistent drip that depletes your oil level between changes.
Frequently Asked Questions
Can I use 5W-30 instead of 5W-20 in my 2014 Jeep Grand Cherokee 3.6L V6?
No. Jeep explicitly specifies 5W-20 for the 3.6L Pentastar engine in normal operating conditions. Using a heavier viscosity like 5W-30 can impede oil flow through the tight tolerances of the variable valve timing system and lower fuel economy.
How often should I check my oil level between changes?
You should check your oil level on the dipstick at least once a month or before embarking on long road trips. Modern engines can consume small amounts of oil during normal operation, and catching low levels early prevents severe engine damage.
What happens if I drive past the oil change indicator?
Exceeding the recommended interval by a few hundred miles will not instantly ruin your engine, but continuously pushing past the limit degrades the oil's additive package, leading to sludge buildup, increased friction, and accelerated wear on internal components.
Is full synthetic oil required for the 2014 Jeep Grand Cherokee Limited?
While synthetic-blend oils meeting MS-6395 are technically compliant, upgrading to a full synthetic oil provides superior thermal stability, better cold-weather flow, and enhanced protection against varnish and deposits, making it the preferred choice for most modern drivers.
Next Actions
If your 2014 Jeep Grand Cherokee Limited is approaching its service mileage, check your specific engine type under the hood or consult your owner's manual to confirm whether you have the 3.6L V6, 5.7L V8, or 3.0L EcoDiesel. Purchase the correct volume of oil bearing the required Chrysler or FCA material standard, along with a high-quality replacement filter, and perform your service promptly to maintain peak vehicle performance.
