Mopar Engine Oil Filter: Why It Matters, How to Choose, and Maintenance Tips for Your Vehicle​

2025-11-24

If you own a Chrysler, Dodge, Jeep, or Ram vehicle—brands under the Stellantis umbrella—you’ve likely heard the term “Mopar” before. Mopar, short for “Motor Parts,” is the official parts and service division of Stellantis, producing OEM (Original Equipment Manufacturer) components designed to keep your vehicle running smoothly. Among these, the Mopar engine oil filter is one of the most critical yet often overlooked parts of your car’s maintenance routine. In this guide, we’ll break down why the Mopar oil filter matters, how to identify genuine units, when to replace them, and best practices to extend both the filter’s life and your engine’s longevity. By the end, you’ll have the knowledge to protect your investment and avoid costly engine damage.

What Does an Engine Oil Filter Do? The Science Simplified

Before diving into Mopar-specific details, let’s clarify the role of any engine oil filter. Your engine relies on motor oil to lubricate moving parts, reduce friction, and dissipate heat. But over time, oil picks up contaminants: dirt, metal shavings from engine wear, soot from combustion, and even tiny particles of rust or debris. Without a filter, these contaminants circulate with the oil, grinding against bearings, pistons, and camshafts—causing premature wear, reduced efficiency, and potentially catastrophic engine failure.

The oil filter acts as a gatekeeper. It traps these particles while allowing clean oil to flow back into the engine. A high-quality filter does this efficiently, balancing two key factors: ​filtration effectiveness​ (how well it captures small particles) and ​flow rate​ (how much oil it can process without restricting circulation). Mopar engineers design their oil filters to meet or exceed the exact specifications of your vehicle’s engine, ensuring optimal performance under all conditions.

Why Choose a Mopar Engine Oil Filter Over Aftermarket Options?

The market is flooded with aftermarket oil filters claiming to be “compatible” with Mopar vehicles. While some may work temporarily, Mopar’s OEM filters offer unique advantages rooted in precision engineering and quality control:

1. ​Engineered for Your Specific Vehicle​

Mopar designs each oil filter to match the exact needs of your engine. This includes factors like:

  • ​Filter media density: Too coarse, and it misses small contaminants; too fine, and it restricts oil flow. Mopar calibrates this to your engine’s tolerance.

  • ​Sealing technology: The gasket and housing are tested to prevent leaks, a common issue with generic filters that may not align perfectly with your engine block.

  • ​Pressure relief valve: Every Mopar filter includes a bypass valve that opens if the filter becomes clogged (e.g., during cold starts or extended intervals), preventing oil starvation. Aftermarket filters may use lower-quality valves that fail prematurely.

2. ​Rigorous Testing Standards​

Mopar subjects its oil filters to extreme testing conditions:

  • ​Flow rate tests: Ensuring oil circulates at the rate your engine requires, even at high RPMs.

  • ​Contaminant retention tests: Measuring how many particles (down to 20 microns or smaller) the filter captures before reaching capacity.

  • ​Temperature and vibration tests: Simulating real-world conditions, from subzero starts to desert heat, to prevent cracks or leaks.

Aftermarket brands often skip these steps, relying on generic certifications that don’t account for your engine’s unique demands.

3. ​Warranty Protection​

Using non-OEM parts can void your vehicle’s warranty, especially if engine damage is traced back to a faulty filter. Mopar filters are guaranteed to work with your vehicle, keeping your warranty intact.

How to Identify a Genuine Mopar Engine Oil Filter

With counterfeit parts flooding online marketplaces, buying a genuine Mopar filter is critical. Here’s how to spot the real deal:

1. ​Check the Packaging​

Genuine Mopar filters come in sealed, labeled boxes with:

  • The Mopar logo (a stylized “M” with a wing) printed in high-resolution color.

  • Your vehicle’s year, make, and model explicitly listed (e.g., “2020-2023 Jeep Wrangler JK”).

  • A part number that matches Mopar’s official catalog (you can verify this on Mopar.com or through a dealership).

Counterfeit boxes may have blurry logos, incorrect vehicle listings, or missing part numbers.

2. ​Inspect the Filter Housing​

Hold the filter in your hand:

  • ​Metal casing: Mopar uses thick, corrosion-resistant steel. Fake filters may feel flimsy or have rough edges.

  • ​Gasket: The rubber gasket should be pliable, not brittle. It should fit snugly around the mounting base without gaps.

  • ​Stamping: Genuine filters have the Mopar logo or part number laser-etched onto the metal, not printed with ink (which can fade or peel).

3. ​Buy from Authorized Dealers​

Purchase Mopar filters directly from:

  • Stellantis dealerships (Chrysler, Dodge, Jeep, Ram).

  • Mopar’s official online store (mopar.com).

  • Reputable auto parts retailers with verified OEM partnerships (e.g., Advance Auto Parts, O’Reilly Auto Parts, when listing “Mopar” as the brand).

Avoid third-party sellers on platforms like eBay or Amazon unless they’re authorized Mopar distributors—many list counterfeit parts at “too good to be true” prices.

When to Replace Your Mopar Engine Oil Filter: Follow the Guidelines

How often should you replace your Mopar oil filter? The answer depends on your driving habits, vehicle model, and the type of oil you use. Here’s a breakdown:

1. ​Standard Recommendations​

Most Mopar vehicles follow the “every 5,000–7,500 miles” rule for oil and filter changes if using conventional oil. If you use synthetic oil (common in newer models), intervals can extend to 10,000–15,000 miles. Always check your owner’s manual—some performance models (e.g., Jeep Wrangler 392) may require more frequent changes due to higher engine stress.

2. ​Severe Driving Conditions​

If you frequently:

  • Tow heavy loads or haul trailers.

  • Drive in extreme heat, cold, or dusty environments.

  • Make short trips (under 10 miles) where the engine doesn’t fully warm up.

You should replace the filter every 3,000–5,000 miles, regardless of oil type. Contaminants build up faster in these conditions, overwhelming the filter.

3. ​Signs It’s Time to Replace​

Don’t wait for the mileage interval if you notice:

  • ​Dark, gritty oil: If you rub a drop of oil between your fingers and feel sand-like particles, the filter is likely clogged.

  • ​Low oil pressure warning light: A restricted filter forces the engine to work harder to pull oil, triggering the sensor.

  • ​Engine noise: A knocking or ticking sound may indicate insufficient oil flow due to a failing filter.

Step-by-Step: How to Replace Your Mopar Engine Oil Filter Safely

Replacing the oil filter is a manageable DIY task, but precision matters. Here’s how to do it correctly:

Tools You’ll Need:

  • Socket wrench or oil filter wrench (size depends on your filter—common sizes are 3/8” or 13mm).

  • Drain pan (large enough to hold 5–7 quarts of oil).

  • New Mopar oil filter (matching your vehicle’s part number).

  • Gloves and safety glasses (oil is hot and can irritate skin/eyes).

  • Funnel and new motor oil (to refill after draining).

Steps:

  1. ​Warm up the engine: Run it for 5–10 minutes to thin the oil, making it easier to drain. Turn off the engine and let it sit for 10–15 minutes.

  2. ​Locate the oil filter: Refer to your owner’s manual—most are on the side of the engine block, near the bottom.

  3. ​Drain the old oil: Place the drain pan under the oil pan (not the filter) and remove the drain plug. Let the oil drain completely (15–20 minutes).

  4. ​Remove the old filter: Use the wrench to loosen it (turn counterclockwise). Be prepared—oil will spill. Wipe the mounting surface with a rag to remove debris.

  5. ​Prep the new filter: Dip your finger in fresh oil and lubricate the gasket on the new Mopar filter. This creates a seal and prevents leaks. Screw the filter into place by hand until tight, then give it a ¼-turn with the wrench (over-tightening can crack the housing).

  6. ​Refill with oil: Replace the drain plug, then use the funnel to add the recommended amount of new oil (check your manual for specs).

  7. ​Check for leaks: Start the engine and let it run for 2–3 minutes. Inspect the filter and drain plug for drips. If there’s a leak, tighten the filter slightly (but don’t overdo it).

Common Mopar Oil Filter Problems and How to Fix Them

Even with genuine Mopar filters, issues can arise. Here’s what to watch for:

1. ​Oil Leaks Around the Gasket​

  • ​Cause: Under-tightening, over-tightening, or a damaged gasket.

  • ​Fix: Remove the filter, inspect the gasket for tears, and reinstall with fresh oil on the gasket. Tighten by hand, then ¼-turn.

2. ​Low Oil Pressure​

  • ​Cause: Clogged filter (contaminants blocking flow) or a failed bypass valve.

  • ​Fix: Replace the filter immediately. If the problem persists, have a mechanic check the bypass valve.

3. ​Filter Cracking or Warping​

  • ​Cause: Exposure to extreme temperatures or using a filter not rated for your engine’s pressure.

  • ​Fix: Always use the Mopar filter specified for your vehicle. Avoid aftermarket “universal” filters.

Extending the Life of Your Mopar Oil Filter (and Your Engine)

Beyond regular replacements, these habits will keep your filter and engine healthy:

  • ​Use the right oil: Mopar recommends specific viscosities (e.g., 5W-20 for many modern engines). Using the wrong oil can cause sludge buildup, overworking the filter.

  • ​Change the oil filter first: When replacing oil, always swap the filter before draining the old oil. This catches debris that would otherwise circulate in the new oil.

  • ​Inspect the filter during oil changes: Hold it up to a light. If you see large particles or the filter media looks clogged, note it—this could indicate underlying engine issues (e.g., worn piston rings).

Final Thoughts: Investing in Mopar Quality Pays Off

Your engine is the heart of your vehicle, and the Mopar engine oil filter is its unsung hero. By choosing genuine OEM filters, replacing them on schedule, and following proper maintenance practices, you’re not just protecting your engine—you’re preserving its resale value, ensuring reliability, and avoiding costly repairs down the road.

Remember: When it comes to oil filters, “close enough” isn’t good enough. Stick with Mopar, and your engine will thank you for years to come.
