The short answer: a genuine Mopar oil filter is the filter your Chrysler, Dodge, Jeep, or Ram engine was designed to use, with the correct media, flow rate, bypass valve setting, anti-drainback valve, and sealing gasket for that specific engine. Replace it every time you change your oil, use the filter that matches your engine by VIN, and you protect bearings, cams, timing components, and turbochargers from the abrasive particles that cause premature wear. Mopar Superstore ships genuine Mopar oil filters nationwide, making it easy to keep a spare on the shelf for your next oil change.

Oil changes are the most common maintenance job any vehicle owner performs, and the filter is the part that makes fresh oil worth paying for. Clean oil running through a clogged or poorly made filter is not clean for long.

When Should You Replace Your Oil Filter?

The simplest rule is also the best one: install a new filter with every oil change. Leaving an old filter in place means a significant amount of dirty oil stays in the system and contaminates the fresh oil immediately, and the filter’s capacity to hold debris keeps shrinking.

Following the Right Schedule

Oil change intervals vary by engine, model year, and how you drive. Many modern Mopar vehicles use an oil life monitoring system that calculates when service is due based on engine operating conditions, and the owner’s manual explains how it works and what maximum interval applies. Towing, extensive idling, dusty roads, short trips, and extreme temperatures typically fall under severe-service conditions and can call for more frequent changes. Always defer to your owner’s manual for your specific vehicle.

Warning Signs Related to Oil Filtration

A filter rarely fails dramatically, but these symptoms suggest an oil or filtration issue that deserves immediate attention:

Symptom	Possible Filter-Related Cause	What to Do
Oil pressure warning light	Low oil level, wrong filter, or a severely restricted filter; also many non-filter causes	Stop the engine safely and check oil level before driving further
Brief ticking or tapping on cold start	Anti-drainback valve not holding oil in the filter, among other possible causes	Confirm the correct filter is installed; have the engine inspected if it continues
Oil leak at the filter	Double gasket, damaged seal, loose or over-tightened filter or cap	Inspect immediately; a large leak can starve the engine of oil
Dark, gritty oil soon after a change	Filter bypassing or not suited to the engine; possible engine wear	Change oil and filter; consider an inspection
Oil life monitor reaches zero or service reminder appears	Scheduled service is due	Change oil and filter and reset the monitor

Never ignore an oil pressure warning. Continuing to drive with low oil pressure can cause severe engine damage in a very short time.

What an Oil Filter Does and How It Works

Engine oil lubricates moving parts, carries heat away from hot spots, and holds contaminants in suspension. Over time it picks up metal particles from normal wear, carbon and soot from combustion, and dust that gets past the air filter. The oil filter’s job is to trap those particles before oil reaches the tight clearances in the bearings, cam phasers, lifters, and turbocharger.

The oil pump draws oil from the pan and pushes it through the filter under pressure. Oil enters the filter, passes through the filter media from the outside in, and exits through the center back into the engine’s oil passages.

Key Parts Inside an Oil Filter

Filter media: a pleated material, often cellulose, synthetic, or a blend, that traps particles while letting oil flow freely.
Anti-drainback valve: a rubber flap that keeps oil from draining out of the filter when the engine is off, so oil pressure builds quickly at startup. It matters most on engines where the filter is mounted sideways or upside down.
Bypass (relief) valve: opens if the media becomes restricted or the oil is very thick on a cold start, so the engine still receives oil. The opening pressure is engineered for each engine.
Gasket or O-rings: seal the filter or housing to the engine.
Housing or canister: a steel can on spin-on filters, or a separate reusable housing on cartridge-style systems.

Spin-On vs. Cartridge Filters

Mopar engines use two main filter styles. A spin-on filter is a complete, sealed steel canister that threads onto the engine. A cartridge filter is just the media element, which drops into a permanent housing with a screw-on cap; the cartridge and its O-rings are replaced, while the housing stays. Some engines, including many versions of the 3.6L Pentastar V6, use a cartridge design, while many HEMI V8s use a spin-on filter. Your VIN lookup will show the right style for your engine.

Our Mopar Oil Filter Selection

Our oil filter category covers genuine Mopar filters for gasoline and diesel engines across the Chrysler, Dodge, Jeep, and Ram lineup, including:

Spin-on filters for HEMI V8 engines and other applications
Cartridge filter elements with matching O-rings for engines that use a filter housing
Filters for turbocharged engines, such as the 2.0L turbo four-cylinder and the 3.0L Hurricane inline-six on some recent models
Heavy-duty filters for diesel engines, including the 6.7L Cummins in Ram HD trucks and the 3.0L EcoDiesel on some earlier models
Filters for older Mopar vehicles still in regular service

An oil change is a good time to tackle other routine items. Pair your filter with a new engine air filter, check the fuel filter if your vehicle has a serviceable one (diesels in particular), see whether your spark plugs are due, or save time with a Mopar maintenance kit.

Finding the Correct Filter by VIN and Engine

Oil filters can look nearly identical while differing in thread size, gasket diameter, bypass setting, or media capacity. Installing the wrong one can cause leaks, poor filtration, or low oil pressure. Here is how to get it right:

Use your VIN. Entering the 17-character VIN on our site identifies the engine your vehicle was built with. You will find it at the base of the windshield on the driver’s side, on the driver’s door jamb label, and on your registration.
Know your engine. Many models offer more than one engine in the same year; a Ram 1500 or Jeep Grand Cherokee, for example, may be equipped with very different powertrains.
Diesel or gas? Diesel engines use filters with different capacity and media requirements.
Buy the gasket or O-ring set if separate. Cartridge filters need fresh O-rings each time; many Mopar cartridge filters include them.
Use the oil your manual specifies. The filter and the oil viscosity and specification work together; your owner’s manual lists the correct oil.

How to Change Your Oil and Filter

Safety note: hot oil can cause burns, so let the engine cool for a while before you begin, but warm oil drains better than cold. Park on level ground, set the parking brake, chock the wheels, and support the vehicle on rated jack stands or ramps if you need to raise it; never work under a vehicle supported only by a jack. Wear gloves and eye protection, and dispose of used oil and filters at a recycling center or a shop that accepts them.

Gather your new genuine Mopar filter, the correct oil type and amount from your owner’s manual, a new drain plug gasket if applicable, a drain pan, a filter wrench or cap socket, and rags.
Run the engine briefly to warm the oil, then shut it off and let it sit a few minutes.
Raise and support the vehicle safely if needed, and remove any splash shield covering the drain plug or filter.
Remove the oil fill cap to help the oil drain, then remove the drain plug and let the oil drain completely into the pan.
Clean the drain plug, install a new gasket if your vehicle uses one, and reinstall the plug to the torque specified in your service information.
For a spin-on filter, place the drain pan underneath and unscrew the old filter. Make sure the old gasket came off with it; a stuck gasket left on the engine will cause a serious leak.
For a cartridge filter, loosen the housing cap (some housings have a drain valve to empty first), remove the old element, and replace the cap’s O-ring with the new one supplied.
Lightly coat the new filter gasket or O-ring with clean engine oil. Install a spin-on filter by hand until the gasket contacts the base, then tighten as directed on the filter or in your service information. Tighten a cartridge cap to its specified torque.
Reinstall any splash shield and lower the vehicle.
Add the correct quantity and type of oil, reinstall the fill cap, and start the engine. The oil pressure light should go out within a few seconds.
Check for leaks at the filter and drain plug, shut the engine off, wait a few minutes, and check the dipstick or level indicator. Top up as needed.
Reset the oil life monitor following the procedure in your owner’s manual.

Genuine Mopar Oil Filters vs. Aftermarket

Consideration	Genuine Mopar Oil Filter	Economy Aftermarket Filter
Engine match	Designed for your engine’s flow, pressure, and filtration needs	Often one filter covers many unrelated engines
Bypass valve setting	Set for your engine’s specification	May differ from factory specification
Anti-drainback valve	Material and design suited to the filter’s mounting angle	Quality varies; some valves harden over time
Media and capacity	Engineered for the intended oil change interval	May have less media or lower capacity
Seal and threads	Correct gasket diameter and thread for a secure seal	Close matches can still leak
Warranty	Backed by the Mopar parts warranty	Depends on brand

The cost difference between a quality filter and a cheap one is small compared with the cost of engine repairs. With modern engines relying on clean oil for variable valve timing and turbocharger lubrication, filtration quality matters more than ever.

Oil Filters Across Chrysler, Dodge, Jeep, and Ram

Chrysler

Chrysler minivans and sedans frequently use the 3.6L Pentastar V6, which on many versions uses a top-mounted cartridge filter housing that makes filter changes relatively clean and accessible. Family vehicles that do a lot of short trips and school runs may fall under severe-service conditions, so check the manual for guidance.

Dodge

Dodge vehicles with HEMI V8 engines often use spin-on filters, while V6 models commonly use a cartridge. Performance models that see hard driving put more stress on their oil, so sticking with the correct filter and keeping an eye on the oil life monitor is wise.

Jeep

Jeep engines range from the 2.0L turbo four-cylinder to the Pentastar V6 and V8 options on some models. Dusty trails and water crossings make clean oil especially important, and the filter style varies by engine, so confirm with your VIN.

Ram

Ram trucks cover the widest range: Pentastar V6, HEMI V8, the 3.0L Hurricane inline-six on some recent models, the 3.0L EcoDiesel on some earlier models, and the 6.7L Cummins diesel in heavy-duty trucks. Diesel filters are larger and designed for the soot and heavy load these engines see, so never substitute a gasoline engine filter on a diesel.

Oil Filter Advice for Different Drivers

Commuters and Family Vehicles

Short trips and heavy traffic can keep oil from reaching full temperature, allowing moisture and fuel to build up. Follow the oil life monitor, change the filter at every service, and take the occasional longer drive to help moisture evaporate from the crankcase.

Towing and Work Trucks

Heavy loads raise oil temperatures and stress. Many owners who tow regularly follow the severe-service schedule. Diesel truck owners should be especially careful to use the correct heavy-duty filter and the oil specification listed in the manual.

Performance Vehicles

High-revving and supercharged engines depend on consistent oil pressure. Stick with the factory filter, check the oil level regularly, and avoid filters that look similar but have different bypass settings.

Off-Road Jeeps

Trail driving brings dust and steep angles. Protect the filter and drain plug with factory skid plates where equipped, inspect for damage after rough trails, and keep the air filter in good shape so less dirt reaches the oil in the first place.

Practical Oil and Filter Care Tips

Check your oil level at regular intervals between changes, especially before road trips and towing.
Keep a record of each change, including date, mileage, and filter used.
Look for leaks under the vehicle; a fresh spot near the filter after a change needs attention right away.
Don’t over-tighten spin-on filters; it can crush the gasket and make the next removal difficult.
While under the hood, inspect your belts and hoses and the coolant level in your radiator reservoir.
Store a spare filter so you’re ready when the service reminder appears.

Frequently Asked Questions

Do I need to change the oil filter every time I change the oil?

Yes, that is the standard recommendation. A used filter holds contaminated oil and has less capacity left to trap new particles, so reusing it undermines the benefit of fresh oil.

Can I use a filter that fits but isn’t specified for my engine?

It isn’t recommended. A filter can thread on correctly yet have a different bypass setting, anti-drainback valve, or media capacity, which can affect oil pressure and filtration. Use your VIN to find the correct genuine Mopar filter.

What’s the difference between a cartridge and a spin-on filter?

A spin-on filter is a sealed canister replaced as a unit. A cartridge filter is a media element that goes inside a permanent housing; you replace the element and its O-rings. Your engine is designed for one or the other.

Why is my oil pressure light flickering after an oil change?

Possible causes include a low oil level, an incorrect filter, a double gasket, or an improperly seated cartridge. Turn the engine off and check for leaks and the correct oil level. If the light stays on, don’t drive the vehicle until it is diagnosed.

Are diesel oil filters different?

Yes. Diesel engines like the 6.7L Cummins produce more soot and have higher oil capacity, so their filters are designed differently. Never substitute a gasoline engine filter.

Should I pre-fill a new oil filter with oil?

On some vertically mounted spin-on filters, owners partially pre-fill to shorten the time it takes to build pressure. On angled or inverted filters, pre-filling can make a mess. Always lubricate the gasket; follow your service information on pre-filling.

Can I order Mopar oil filters in multiples?

Yes. Many owners order several filters at once so they’re ready for future services. Mopar Superstore ships nationwide, so you can stock up and have them delivered to your door.
