Everything You Need to Know About Mopar Oil Filters: Selection, Maintenance, and Why They Matter for Your Vehicle​

2025-11-24

If you own a Chrysler, Dodge, Jeep, or Ram vehicle—brands under the Mopar umbrella—you’ve likely heard the term “Mopar oil filter” thrown around during routine maintenance. But what makes these filters different, and why does choosing the right one matter? In short: Mopar oil filters are engineered specifically for your vehicle’s engine, ensuring optimal performance, longevity, and protection against costly damage. Using a non-Mopar filter or neglecting proper maintenance can lead to reduced engine life, poor fuel efficiency, or even catastrophic failure. This guide will break down everything you need to know about Mopar oil filters, from how they work to selecting the correct model, installing them correctly, and avoiding common pitfalls.

What Is a Mopar Oil Filter, and How Does It Work?

At its core, a Mopar oil filter is a small but critical component of your vehicle’s lubrication system. Its primary job is to remove contaminants from engine oil—such as dirt, metal shavings, soot, and sludge—before the oil circulates through the engine. Over time, these particles can grind against moving parts, causing wear, overheating, and reduced efficiency.

Mopar designs its oil filters to meet the exact specifications of Chrysler, Dodge, Jeep, and Ram engines. Unlike generic aftermarket filters, which may prioritize cost-cutting over precision, Mopar filters are engineered with:

  • ​High-quality filtration media: Multi-layered paper or synthetic materials that capture 99% of particles as small as 20 microns (about the thickness of a human hair).

  • ​Durable construction: Steel or aluminum housings resistant to rust and high pressure, ensuring they withstand extreme temperatures (from sub-zero winters to desert heat).

  • ​Precision fitment: Exact threading, gasket size, and overall dimensions to seal perfectly with your engine block, preventing leaks.

  • ​Engineered bypass valves: If the filter becomes clogged (e.g., during cold starts or extended intervals between changes), a spring-loaded valve opens to let unfiltered oil flow, protecting the engine from oil starvation.

Without a functioning Mopar oil filter, contaminants build up in the oil, leading to accelerated wear on critical components like camshafts, bearings, and pistons. Over months or years, this can result in expensive repairs—sometimes costing thousands of dollars.

Why Choose a Mopar Oil Filter Over Aftermarket Options?

The aftermarket is flooded with oil filters claiming to be “compatible” with Mopar vehicles. So why invest in the OEM (Original Equipment Manufacturer) option? Here’s why Mopar filters are worth the extra cost:

1. ​Guaranteed Compatibility​

Mopar filters are designed alongside your vehicle’s engine during development. This means every dimension, thread pitch, and gasket material is tested to work seamlessly with your car, truck, or SUV. Aftermarket brands may claim “universal fit,” but slight variations in size or sealing technology can cause leaks, reduced filtration efficiency, or even damage to the engine block.

For example, a Jeep Wrangler JK with a 3.6L Pentastar engine requires a filter with specific threads (16x1.5mm) and a gasket diameter of 2.5 inches. A generic filter might list “Jeep Wrangler” compatibility but use 16x1.25mm threads, leading to a loose fit and oil leaks. Mopar eliminates this guesswork.

2. ​Superior Filtration Performance​

Mopar tests its filters under rigorous conditions, including high RPMs, extreme temperatures, and prolonged use. Their multi-stage filtration media traps smaller particles than many aftermarket options, reducing wear on engine parts. Third-party tests by organizations like the International Lubricant Specification Advisory Committee (ILSAC) often show Mopar filters outperform budget competitors in capturing fine particulates.

3. ​Warranty Protection​

Using non-OEM parts can void your vehicle’s warranty. If an aftermarket filter fails and causes engine damage, Chrysler, Dodge, Jeep, or Ram may deny coverage. Mopar filters, being OEM, ensure you’re protected under the original new vehicle warranty or extended service plans.

4. ​Consistent Quality Control​

Mopar’s manufacturing facilities follow strict ISO/TS 16949 quality standards, meaning every filter undergoes inspections for leaks, burst pressure, and filtration efficiency. Aftermarket brands may source materials from multiple suppliers, leading to inconsistent performance.

How to Select the Right Mopar Oil Filter for Your Vehicle

Choosing the correct Mopar oil filter isn’t as simple as grabbing the first one off the shelf. Here’s how to ensure you get the right match:

Step 1: Identify Your Vehicle’s Engine

Start by noting your vehicle’s make, model, year, and engine type. For example, a 2020 Ram 1500 with a 5.7L Hemi V8 has different filtration needs than a 2022 Dodge Challenger SRT Hellcat with a 6.2L supercharged V8.

Step 2: Check Your Owner’s Manual

Your owner’s manual is the most reliable source for filter specifications. Look for the “Maintenance” or “Specifications” section, which lists the part number for the factory-recommended oil filter. Mopar part numbers typically start with letters like “OC” (e.g., OC 558) followed by numbers.

Step 3: Cross-Reference with Mopar’s Online Catalog

If you don’t have the manual, visit Mopar’s official website. Their parts lookup tool lets you enter your VIN or vehicle details to find the exact oil filter part number. This ensures you’re getting the filter designed for your engine’s specific demands (e.g., high-torque diesel engines vs. high-revving gasoline engines).

Step 4: Consider Driving Habits

If you frequently tow, drive in stop-and-go traffic, or operate in dusty environments, your engine accumulates contaminants faster. While Mopar filters are rated for standard intervals (typically 5,000–7,500 miles), you may want to opt for a high-capacity filter (if available) or shorten your change interval to 3,000–5,000 miles.

How to Install a Mopar Oil Filter: Step-by-Step Guide

Installing a new Mopar oil filter is a straightforward DIY task if you have the right tools and follow these steps:

Tools You’ll Need:

  • Socket wrench or oil filter wrench (size depends on your filter’s diameter; most Mopar filters use a 3-inch or 3.5-inch wrench)

  • New Mopar oil filter (correct part number)

  • Funnel

  • Gloves and safety glasses

  • Rags or shop towels

  • Oil catch pan

Step 1: Warm Up the Engine (Optional but Recommended)

Run the engine for 2–3 minutes to warm the oil. Warm oil flows more easily, helping drain old oil and reducing mess.

Step 2: Drain the Old Oil

Locate the oil pan under your vehicle and place the catch pan beneath it. Remove the drain plug with a socket wrench, let the oil drain completely (10–15 minutes), then replace the drain plug and tighten it to the torque specification in your manual (usually 20–30 ft-lbs).

Step 3: Remove the Old Oil Filter

Use the oil filter wrench to loosen the old filter. Be cautious—the filter may be hot. Once loose, unscrew it by hand and lower it into the catch pan. Wipe the filter mounting surface on the engine block with a rag to remove any leftover gasket material.

Step 4: Install the New Mopar Filter

  • Dip your finger in fresh oil and apply a thin layer to the rubber gasket on the new filter. This ensures a proper seal and prevents the gasket from sticking or tearing during installation.

  • Screw the filter onto the engine block by hand until the gasket makes contact, then tighten it an additional ¾ to 1 full turn. Do not overtighten—this can damage the gasket or housing, leading to leaks.

Step 5: Refill with New Oil

Using a funnel, pour the recommended type and amount of Mopar motor oil into the engine (check your manual for specs—e.g., 5W-20 for most modern Jeep engines).

Step 6: Check for Leaks and Reset the Maintenance Light

Start the engine and let it run for 1–2 minutes. Inspect the filter and drain plug for leaks. If everything looks good, turn off the engine, wait 5 minutes, and check the oil level with the dipstick, adding more if needed. Finally, reset the oil change reminder light using your vehicle’s infotainment system or a scan tool.

Common Mistakes to Avoid with Mopar Oil Filters

Even with the right filter, improper installation or maintenance can cause problems. Here are the most common errors to avoid:

1. Using the Wrong Part Number

As mentioned earlier, using a filter not designed for your engine can lead to leaks or reduced filtration. Always cross-reference with your manual or Mopar’s online catalog.

2. Overtightening the Filter

Over-tightening can crack the filter housing or damage the gasket, causing oil leaks. Stick to the “hand-tight plus ¾ turn” rule.

3. Neglecting the Gasket

Always replace the gasket on the new filter—never reuse the old one. A damaged or dried-out gasket won’t seal properly, leading to leaks.

4. Skipping the Pre-Oil Wipe

Failing to wipe the mounting surface can leave old gasket material behind, preventing the new filter from sealing correctly.

5. Ignoring the Bypass Valve

If you drive in extremely cold climates, let the engine idle for a minute after starting to warm the oil. This ensures the filter isn’t clogged with cold, thick oil, which could force the bypass valve open prematurely.

How Often Should You Replace Your Mopar Oil Filter?

Mopar recommends changing your oil and filter every 5,000–7,500 miles under normal driving conditions. However, this interval can vary based on:

  • ​Driving environment: Dusty roads, towing, or off-roading increase contaminant buildup—shorten the interval to 3,000–5,000 miles.

  • ​Oil type: Synthetic oil lasts longer than conventional oil. If you use synthetic, follow your manual’s extended interval (often 7,500–10,000 miles).

  • ​Engine age: Older engines with worn seals may shed more metal shavings, requiring more frequent filter changes.

Check your owner’s manual for your vehicle’s specific schedule, and use the “oil life monitor” in your dashboard (if equipped) as a guide.

Signs Your Mopar Oil Filter Needs Replacement

Even if you follow the recommended interval, watch for these warning signs that your filter may be failing:

  • ​Dark, gritty oil: If your oil looks like coffee with milk, the filter isn’t trapping contaminants effectively.

  • ​Low oil pressure warning light: A clogged filter can restrict oil flow, triggering the warning.

  • ​Engine noise: Loud knocking or ticking sounds may indicate metal-on-metal wear from contaminated oil.

  • ​Oil leaks: A loose or damaged filter gasket can cause oil to pool under your vehicle.
