The 2020 Jeep Grand Cherokee offers multiple engine options, and each demands a specific oil filter design. Choosing the wrong type—cartridge versus spin-on—can lead to leaks, poor filtration, or restricted oil flow. I’ve analyzed the factory specifications, filtration data, and long-term owner reports to identify the parts that consistently deliver reliable protection for every Grand Cherokee engine.
I’m Amir — the founder and writer behind Four Wheel Ask. I’ve spent years studying automotive filtration engineering, comparing micron ratings, burst strengths, and media composition data to help owners make informed maintenance decisions without relying on brand marketing.
Below, I break down the top options based on build quality, owner-reported fitment issues, and real-world filtration performance. Selecting the correct 2020 jeep grand cherokee oil filter is the single most critical factor for protecting your engine and maximizing its service life.
How To Choose The Best 2020 Jeep Grand Cherokee Oil Filter
Matching the correct oil filter to your specific Grand Cherokee engine is the single most important step in any oil change. Using the wrong type—or a filter with an improper bypass valve setting—can trigger oil pressure warnings, reduce filtration efficiency, or cause a complete seal failure.
Cartridge vs. Spin-On Identification
The 3.6L Pentastar and 3.0L EcoDiesel engines use cartridge style elements that drop into a reusable housing on the top of the engine. The 5.7L and 6.4L HEMI engines use a traditional spin-on metal canister mounted on the side of the block. Confusing the two is physically impossible unless an aftermarket conversion kit is used, but buyers must be certain of their engine code before ordering.
Media Composition and Efficiency
Filter media falls into three categories: cellulose, synthetic blend, and full synthetic. Cellulose is fine for standard 5,000-mile intervals. Synthetic blends (common in OEM filters) offer better flow consistency. Full synthetic media, found in premium aftermarket filters, provides superior particle retention and extended service life, making it worthwhile for drivers who use severe-service schedules or synthetic oils.
OEM vs. Premium Aftermarket Trade-Offs
Mopar filters are calibrated specifically to Chrysler’s oil pump curves and bypass valve settings, guaranteeing zero compatibility risk. Premium aftermarket filters like the PurolatorBOSS or K&N offer higher dirt-holding capacities and stronger casings. The trade-off is that not all aftermarket filters match the exact bypass pressure of the factory part, which can matter under extreme cold or high-rpm conditions.

In‑Depth Reviews
1. Purolator PBL12222
The PurolatorBOSS series represents the top tier of consumer spin-on filtration. Its SmartFUSION full synthetic media is engineered to capture over 99% of contaminants while maintaining high flow rates, making it an excellent choice for owners who push their Grand Cherokee hard—whether towing, off-roading, or daily commuting.
Handling the extreme pressure demands of a HEMI’s variable displacement oil system is no small task, but the heavy-duty steel casing and double-helix center tube provide the structural integrity needed to avoid collapse during cold starts or high-rpm operation. The silicone anti-drainback valve further prevents dry starts, which significantly reduces bearing wear over the vehicle’s life.
Owner feedback consistently highlights the filter’s ability to hold up over extended intervals, with several users reporting clean oil analysis results past 7,500 miles. While perfectly compatible with conventional oil, this filter truly shines when paired with a high-quality full synthetic.
What works
- Excellent 99%+ filtration efficiency
- Silicone anti-drainback valve for immediate lubrication
What doesn’t
- Spin-on design restricts use to HEMI and V8 applications only
- Premium pricing versus standard filters
2. K&N HP-7042
K&N’s HP-7042 is engineered for drivers who prioritize oil flow rate and easy maintenance. The welded hex nut on the dome allows for simple wrench removal without special tools, a welcome feature for those performing their own oil changes on a tight schedule or in tight spaces.
The pleated synthetic-blend media offers a balance between high dirt-holding capacity and low flow restriction. While its micron rating is slightly higher than some competitors, the trade-off is superior oil delivery under high-load conditions, which benefits the 5.7L and 6.4L engines during spirited driving or towing.
The heavy-duty canister construction meets strict burst strength requirements. Owner reports are overwhelmingly positive regarding fitment on Ram and Jeep HEMI applications, with many noting the filter’s consistent performance across 7,000-mile intervals.
What works
- Wrench-off nut simplifies removal
- Robust construction for high-pressure systems
What doesn’t
- Does not meet OEM micron spec for some critical applications
- Spin-on design limits compatibility
3. Mopar 04892339AB
When absolute factory-spec assurance is required, the Mopar 04892339AB is the definitive choice for the 5.7L and 6.4L Grand Cherokee engines. Engineered specifically for Chrysler’s oiling system, it matches the exact bypass valve setting, thread pitch, and sealing surface required for a leak-free seal.
The filter media is calibrated to Chrysler’s own performance benchmarks, balancing particle retention with flow restriction over the recommended 5,000- to 7,000-mile oil change interval. The steel canister construction provides predictable burst resistance under cold-start pressure spikes common in colder climates.
Owner reports indicate flawless fitment and zero reported failures when paired with the correct viscosity oil. For warranty-conscious owners or those seeking the absolute lowest risk of any fitment issue, this is the benchmark.
What works
- Guaranteed OEM fit and function for HEMI engines
- Calibrated bypass valve matches factory oil circuit
What doesn’t
- Does not offer extended service interval warranty

Hardware & Specs Guide
Filtration Media
Cellulose filters are the baseline and handle standard intervals without issue. Synthetic-blend media (used in OEM Mopar filters) improves flow consistency and particle retention. Full synthetic media (found in the PurolatorBOSS) delivers the highest efficiency and allows for extended service intervals up to 20,000 miles. The media type directly dictates how fine a particle the filter can catch and how much oil flow is restricted.
Anti-Drainback Valve
This valve prevents oil from draining out of the filter when the engine is off, ensuring immediate lubrication on startup. Silicone valves (PurolatorBOSS, K&N) provide longer service life and maintain their seal better in high-heat environments compared to standard nitrile rubber valves. This is a critical spec for engines that experience frequent cold starts or extended idle periods.
