To keep your 2014 Jeep Grand Cherokee running at its peak, selecting the correct engine oil is critical. This guide provides factual, vehicle-specific insights into oil types, capacities, and trusted options to ensure smooth operation and long-lasting engine health.
Oil Specifications for 2014 Jeep Grand Cherokee
Oil capacity varies by engine: The 3.6L Pentastar V6 holds 6 quarts with a filter, the 5.7L HEMI V8 requires 7 quarts, and the 3.0L EcoDiesel needs 8 quarts. These capacities include the oil filter and must be followed to avoid underfilling or overfilling, both of which can affect performance and durability.
Engine variants are distinct: Jeep offered three engines for 2014: the 3.6L Pentastar V6, the 5.7L HEMI V8, and the 3.0L EcoDiesel V6. Each engine has unique lubrication needs tied to its design, displacement, and emissions equipment, which is why matching oil type and capacity is critical.
OEM standards define compatibility: Chrysler filled the Pentastar and HEMI with Mopar synthetic 5W-20 meeting MS-6395, while the EcoDiesel uses oil meeting MS-11106. These standards cover properties such as soot control, oxidation resistance, and additive chemistry, ensuring that any oil carrying the approval is fully compatible with the engine and its emissions system.
Using the recommended oil ensures proper lubrication, minimizes wear, and enhances fuel economy for your Grand Cherokee.
⚠️ NOTICE: Warranty & Oil Choice — Know Your Rights
I’ve stood across from too many fleet managers and mechanics who were told by their OEM dealer that only the dealer’s oil will keep their warranty safe. That’s scare tactics, plain and simple. The Magnuson-Moss Warranty Act makes it crystal clear: Jeep can recommend Mopar oil, but they cannot require you to buy it unless they’re willing to hand it over for free.
What really matters is that the oil meets Chrysler’s published specifications — MS-6395 for gasoline engines and MS-11106 for the EcoDiesel. If your oil carries those approvals and matches the required viscosity grade, your warranty is protected no matter what brand name is on the label.
After 45 years working with B2B clients who run expensive equipment, I’ve seen the cost of following sales pressure instead of the specs. The truth is simple: you have the right to choose oils that meet or exceed the published standards, and no dealer can take that away. That’s the law, and it protects you.

Oil Change Intervals for 2014 Jeep Grand Cherokee
Chrysler recommends oil changes at 7,500 miles or six months under normal driving conditions.
For severe duty—such as frequent towing, off-road use, extreme temperatures, or extended idling—shorten the interval to every 3,500–5,000 miles.
Following these ranges ensures the oil maintains its protective qualities and the additive package remains effective for wear control, deposit management, and emissions system protection.
Oil Filter Options for 2014 Jeep Grand Cherokee
Filter changes are mandatory: Every oil change requires replacing the filter to keep the oil free of debris and maintain wear protection. A fresh filter ensures contaminants don’t circulate back into the engine, preserving lubrication quality across the service interval.
Pentastar V6 filter options: The 3.6L V6 uses Mopar MO-349 as the OEM filter, with alternatives such as Fram PH10060, Wix 57356, and K&N HP-2010. These cross-references provide the same fit and filtration efficiency when OEM parts are not available.
HEMI V8 filter options: The 5.7L HEMI relies on Mopar MO-899, which can be substituted with Fram PH2, Wix 57899, or K&N HP-2009. Using a high-quality filter is essential to meet Chrysler’s efficiency and flow requirements under the HEMI’s higher oil volume.
EcoDiesel V6 filter options: The 3.0L EcoDiesel requires Mopar MO-339, cross-referenced to Fram XG11665, Wix 10060, and K&N HP-7026. Diesel engines demand filters with higher soot-handling capacity, making proper selection critical to maintain oil cleanliness and emissions system protection.
Using the Mopar OEM filter ensures exact fit and meets Chrysler’s efficiency and capacity requirements. Cross-referenced aftermarket filters are acceptable as long as they meet or exceed the same specifications.
Quick Reference: Good, Better, Best Oil Choices
Good means meeting OEM minimums: Full synthetic SAE 5W-20 oils with Chrysler MS-6395 approval cover the gasoline engines, while 5W-30 oils meeting MS-11106 are required for the EcoDiesel. These provide the baseline level of wear protection, emissions compatibility, and warranty compliance that Jeep specifies.
Better offers enhanced protection: Oils blended with stronger detergents and improved oxidation resistance keep engines cleaner over time. This option gives extra margin in high-mileage or mixed-duty driving where deposits and heat stress are more demanding.
Best supports severe duty and longevity: Premium synthetics with advanced additive chemistry allow extended drain intervals, deliver maximum wear protection, and hold viscosity under extreme load. These oils are best suited for towing, off-road use, or continuous heavy-duty operation where standard oils may fall short.
This framework helps owners match oil choice to budget, duty cycle, and performance expectations without bias toward any single brand.
Oil Viscosity and Climate Considerations
Ambient temperature plays a direct role in choosing the right viscosity grade for the 2014 Jeep Grand Cherokee.
Cold climates demand low-W oils: In freezing conditions, lower “W” grades such as 0W-20 or 0W-40 circulate faster at startup. This reduces metal-to-metal contact during the first seconds after ignition, which is when the majority of engine wear occurs, especially in northern winters.
Moderate to warm climates suit 5W-20: Chrysler’s standard 5W-20 specification balances fuel economy, lubrication, and emissions performance for typical year-round use. This viscosity grade provides stable protection under most daily driving conditions without sacrificing efficiency.
Heavy load and high heat need stability: When towing, off-roading, or operating in sustained high ambient temperatures, oils with higher thermal resistance such as 0W-40 synthetics or diesel-rated 5W-30 meeting MS-11106 perform best. These grades resist thinning, control oxidation, and keep film strength intact under stress.
Selecting viscosity with climate in mind ensures the oil film maintains integrity during startup and severe duty operation.
DIY Service Notes for 2014 Jeep Grand Cherokee
Owners performing their own oil changes should follow Chrysler’s service specifications to ensure reliability:
Drain plug torque is precise: Both gasoline and diesel versions of the 2014 Jeep Grand Cherokee require 20 ft-lbs on the drain plug. Using the correct torque prevents stripped threads or leaks while ensuring the plug seats properly.
Oil pan capacities must be exact: With the filter installed, the 3.6L V6 holds 6 quarts, the 5.7L V8 requires 7 quarts, and the 3.0L EcoDiesel needs 8 quarts. Following these capacities avoids problems caused by overfilling or low oil levels.
Correct tools ensure accuracy: A standard metric socket set, an oil filter wrench sized to the specific filter, and a torque wrench are required for dependable service. These tools allow the job to be done to factory specifications, reducing the risk of mistakes.
Safety practices protect the mechanic: Always support the Jeep with jack stands on level ground before draining oil. Used oil and filters should be taken to a certified recycling facility to meet environmental regulations and avoid improper disposal.
For complete service instructions, always cross-check with the Jeep Grand Cherokee owner’s manual or official Chrysler service literature.

FAQ’s
What happens if I use 5W-30 instead of 5W-20 in my 2014 Jeep Grand Cherokee?
Chrysler specified SAE 5W-20 for the 3.6L Pentastar V6 and 5.7L HEMI V8 in 2014 because those engines were calibrated around that viscosity for fuel economy targets, oil pump design, and valvetrain clearances.
Using 5W-30 won’t immediately “damage” the engine — both are multigrades that flow well in cold starts — but the thicker 30-weight film at operating temperature can create subtle differences:
Fuel economy and emissions are impacted: Chrysler and the EPA certified the Pentastar and HEMI engines with 5W-20, meaning that viscosity was built into the calibration. Switching to 5W-30 can reduce efficiency slightly and raise tailpipe emissions above the intended design.
Oil pressure and flow characteristics differ: A 5W-30 can raise hot oil pressure but reduce flow in tighter clearances. This may interfere with components such as variable valve timing systems that depend on precise oil flow.
Warranty compliance depends on approval: Chrysler requires oils meeting MS-6395 for gasoline engines. Using 5W-30 without that approval places the fill outside OEM guidance, which could complicate warranty coverage if questioned.
Severe duty may justify exceptions: In heavy-load or high-heat conditions such as mountain towing or desert off-road driving, some professionals recommend 30-weight oil for added margin against thinning. However, this remains outside Chrysler’s published recommendations.
Bottom line: 5W-20 is the engineered spec for the Pentastar and HEMI. A switch to 5W-30 isn’t catastrophic, but it’s not optimal unless you have a compelling severe-duty reason — and even then, make sure the oil carries MS-6395 approval.
Can I mix oil brands in my 2014 Jeep Grand Cherokee?
Yes, you can top off with a different brand in an emergency, but there are important caveats. All motor oils meeting the same API service category (SN, SN Plus, SP) and Chrysler approvals (MS-6395 for gasoline, MS-11106 for EcoDiesel) are formulated to be chemically compatible. That’s by design — otherwise the entire service industry would collapse.
But mixing isn’t ideal for several reasons:
Additive packages are not identical: Each brand uses its own mix of detergents, dispersants, and anti-wear agents, which can behave differently in service. For instance, calcium-based detergents and magnesium-based detergents manage soot and deposits in distinct ways, and mixing them may dilute intended performance.
Consistency in protection is reduced: Oils are tested and certified as complete systems, with all additives working together. Combining two formulations removes the certainty of how antioxidants, friction modifiers, and viscosity improvers will perform over a full service interval.
Warranty compliance focuses on specification: Chrysler’s requirement is that the oil in the sump meets MS-6395 for gasoline or MS-11106 for diesel. If a top-off oil carries the same approval, warranty coverage is preserved regardless of brand.
Practical guidance allows limited mixing: Occasional mixing to finish an interval or reach a service point is acceptable. For best results, ensure the top-off oil matches viscosity grade and Chrysler approval, then return to a single brand at the next scheduled oil change.
Bottom line: Mixing won’t destroy your engine, but for best long-term results stick to one brand and formulation per oil change. Consistency is what keeps wear control, sludge resistance, and emissions protection at their design levels.
How do I reset the oil life monitor on a 2014 Jeep Grand Cherokee?
The Oil Life Monitor (OLM) doesn’t automatically reset when you change oil — it must be manually cleared so the system can track the next interval correctly. Chrysler designed the process so owners can do it without tools:
Ignition must be set correctly: Begin by turning the ignition to the “ON/RUN” position without starting the engine. This ensures the electronic systems are active while the engine remains off.
Accelerator sequence resets the system: Slowly press the accelerator pedal fully to the floor three times within 10 seconds. This input signals the control module to reset the oil life monitor.
Ignition cycle confirms reset: After pressing the pedal, turn the ignition back to the “OFF/LOCK” position. Restart the vehicle, and the oil change reminder should display 100% life remaining.
Accuracy depends on ignition mode: The reset only works when the ignition is in “RUN,” not during an engine start sequence. If the reset fails, repeat carefully as timing errors are common.
System is algorithm-based, not sensor-driven: The oil life monitor uses mileage, duty cycle, and temperature to estimate oil life rather than testing the oil directly. Resetting it aligns maintenance reminders with actual service intervals.
Why It Matters: Leaving the OLM uncleared causes false reminders and may lead to confusion on intervals. Resetting at every oil change ties your maintenance log to Chrysler’s engineering expectations, whether you follow the normal 7,500-mile schedule or shorten for severe duty.
Conclusion
Whether your 2014 Jeep Grand Cherokee carries the Pentastar V6, the HEMI V8, or the EcoDiesel, the foundation of long-term reliability comes down to disciplined oil choice and maintenance.
Chrysler’s MS-6395 and MS-11106 standards aren’t arbitrary—they reflect years of engineering around wear control, emissions compliance, and real-world durability. Matching viscosity to climate, duty cycle, and towing load keeps the oil film stable where it matters most.
Filters, torque specs, and service intervals may seem like small details, but in practice they separate engines that reach 200,000 miles from those that fail prematurely.
Owners who respect these standards, use the right oil consistently, and reset the oil life monitor properly will have confidence that their Jeep is protected for the next adventure—whether that’s daily highway miles or off-road trails.
At the end of the day, oil choice isn’t about brand loyalty. It’s about engineering compliance, duty-specific protection, and the peace of mind that comes from knowing your Grand Cherokee is running on the chemistry it was designed to use.
