Oil-filter listings can be confusing when a product title, fitment tool, and service manual do not use the same wording. The FRAM Extra Guard CH6015 Oil Filter is a compact cartridge element for select motorcycles, ATVs, and UTVs, but it only works when the part number matches your exact engine. This review explains its verified dimensions, filter design, fitment range, installation needs, and 10,000-mile marketing claim. Its strengths are broad powersports coverage, an included O-ring, and everyday filtration, while its main limitation is the need for careful fitment and service-interval checks.
Quick Verdict
Rating: 8/10
Best For: Owners of a confirmed CH6015-compatible motorcycle, ATV, or UTV who want an aftermarket cartridge filter for routine oil changes.
Bottom Line: The FRAM CH6015 is a practical replacement when its dimensions and cross-reference match your engine. Its included O-ring and bypass valve add useful service value, but you should follow your vehicle’s shorter maintenance interval instead of assuming every application can run 10,000 miles.

What Is the FRAM Extra Guard CH6015?
The FRAM Extra Guard CH6015 is a replaceable cartridge filter element that sits inside an engine’s oil-filter housing. Unlike a spin-on filter, it does not have a metal can or threaded base that screws directly onto the engine. You remove the housing cover, replace the internal element and O-ring, then reinstall the cover to the torque listed in the service manual.
FRAM uses a cellulose/synthetic media blend in this filter. The company markets the Extra Guard line for conventional and synthetic oil and states protection for up to 10,000 miles. The product listing also promotes 95% dirt-trapping efficiency, but FRAM’s published test note is based on average results from selected Extra Guard reference filters, not a separate CH6015-specific efficiency report.
This filter is made for a wide but vehicle-specific range of Honda, Kawasaki, Polaris, and Suzuki powersports engines. That range includes street motorcycles, dirt bikes, ATVs, and UTVs, so the brand name or engine size alone is not enough to confirm compatibility.
Before You Buy: Confirm CH6015 in your owner’s manual, FRAM’s fitment catalog, or a trusted cross-reference. Some marketplace text describes it as a spin-on filter with an anti-drainback valve, but FRAM’s part-specific specifications identify it as a cartridge with no anti-drainback valve.
Who Should Buy It?
Best For
- Owners replacing an existing CH6015, HF112, KN-112, 24944, or another confirmed cross-reference.
- DIY riders whose filter housing uses the CH6015 element and supplied O-ring dimensions.
- Motorcycle, ATV, or UTV owners who want a known aftermarket brand for routine service.
Skip If
- Your manual lists a different filter element or O-ring size.
- Your service plan requires an OEM filter for warranty or record-keeping reasons.
- You want to extend the oil-change interval beyond the schedule set by the engine manufacturer.
Filter Media and Dirt Control
The CH6015 uses cellulose/synthetic filter media. Cellulose fibers provide a large surface for trapping normal engine contaminants, while synthetic material can improve strength and flow compared with a basic paper-only element. For regular street, trail, or utility use, this design targets a balance between dirt capture and oil flow rather than racing-level filtration.
FRAM promotes 95% dirt-trapping efficiency across this product listing. That figure is useful as a broad line claim, but it should not replace your engine maker’s maintenance schedule. Dusty trails, repeated short trips, hot operation, fuel dilution, or hard competition use can shorten both oil and filter life.
Cartridge Design and Included O-Ring
The cartridge format reduces the amount of metal discarded during a filter change because you replace the internal element instead of a complete metal canister. The CH6015 is 1.484 inches tall, 1.969 inches wide at the bottom, and has a 0.469-inch opening through the center. Those dimensions are useful when comparing the new part with the element removed from your engine.
FRAM includes a replacement O-ring measuring 2.094 inches inside, 2.296 inches outside, and 0.094 inches thick. Replacing the housing seal is important because an old, flattened, twisted, or damaged O-ring can leak even when the new filter element is correct.
Bypass Valve and Oil Flow
The CH6015 includes a bypass relief valve rated at 18 to 22 psi. A bypass valve can allow oil to keep moving if the filter media creates too much restriction, such as during a cold start or when the element is heavily loaded. It is a protective flow feature, not a reason to leave dirty oil or an overdue filter in service.
This part does not have an anti-drainback valve. That is normal for many cartridge designs because oil retention depends on the engine’s housing and oil passages. You should not judge compatibility by comparing this element with the valve features of a spin-on automotive filter.
Fit and Compatibility
FRAM lists CH6015 for many Honda models, including selected CBR300R, Rebel 300, CRF250L, Rancher, Foreman, Pioneer, XR, and older FourTrax applications. Kawasaki coverage includes selected Z125 Pro, KLX, KX450F, KFX450R, and Super Sherpa models. The catalog also lists certain Polaris Predator and Outlaw 500 models and selected Suzuki DR-Z110 years.
Those examples do not cover every compatible year, and similar model names may use different filters after an engine update. Use the exact year, model, trim, and engine when checking fitment. A cross-reference such as HiFlo HF112 or K&N KN-112 is helpful only when the original filter number for your engine matches that interchange.
Fit Checks Before You Drain the Oil
- Confirm CH6015 or a listed cross-reference in your service information.
- Check that the replacement package includes an undamaged O-ring.
- Compare the new element’s height, diameter, center opening, and end shape with the old filter.
- Make sure the housing cap, spring, washer, and other reusable parts are present and installed in the correct order.
Installation and Maintenance
Installation varies by engine, so use your motorcycle, ATV, or UTV service manual for access steps, filter orientation, fastener sequence, and torque. Work on a stable vehicle, let the engine cool enough to avoid burns, and wear gloves because used motor oil should not stay on bare skin.
After draining the oil, remove the filter-housing cover and old cartridge. Note the direction of the old element and the location of any spring, washer, or retainer. Remove the old O-ring, clean the sealing groove and housing, and check that no gasket material or debris remains.
Coat the new O-ring lightly with clean engine oil, place it in the correct groove without twisting it, and install the new filter in the same orientation required by the manual. Refit the housing cover and tighten it to the specified torque. Do not guess, overtighten the cap, or use the generic hand-tightening method intended for spin-on filters.
Pro Tip: Lay the removed filter, O-ring, spring, washer, and cover on a clean towel in their installed order. This simple step makes it easier to confirm orientation before you close the housing.
How It Performs in Real Use
For Routine Street Riding
For a compatible street motorcycle, the CH6015 offers a straightforward service part with published dimensions and a supplied housing seal. It works with conventional, synthetic, or blended oil when that oil meets the viscosity and specification in your manual.
For Trail and Off-Road Use
ATVs and dirt bikes can see more dust, heat, low-speed work, and repeated high-load operation than a typical commuter motorcycle. The filter can still be suitable, but the engine maker’s severe-service interval should control the change schedule. Inspect air-filtration and oil condition as part of the same maintenance routine because off-road contamination often starts on the intake side.
For Utility ATV and UTV Work
Frequent idling, towing, hauling, and low-speed use can add heat and operating hours without adding many road miles. In these machines, track engine hours and calendar time when the manual uses them. A 10,000-mile filter claim may be less meaningful than the vehicle’s hour-based service requirement.
For Older Powersports Engines
CH6015 fits several older Honda, Kawasaki, and Polaris applications, which makes cross-reference accuracy especially useful when an original part number is hard to source. Before installation, inspect the housing cap, spring, sealing surface, and threads for wear. A new filter cannot correct a damaged housing or an oil-pressure problem.
How to Use It Correctly
Buy the filter before draining the engine and verify the part against the filter you plan to remove. Keep the package closed until the work area is clean, and do not install an element with crushed pleats, damaged end caps, or contamination on the media.
Refill the engine with the exact oil grade and quantity listed by the manufacturer. Start the engine only after confirming the drain plug, filter cover, and fill cap are secure. Let it run briefly, inspect the housing and drain area for leaks, shut it off, wait as directed by the manual, and recheck the oil level.
Record the date, mileage, and engine hours after service. Recycle the used oil and filter through an approved collection site. Never pour used oil into soil, drains, or household trash.
Compatibility and Safety
The filter is part of the engine’s pressurized lubrication system, so a wrong element, pinched O-ring, reversed cartridge, loose cover, or overtightened housing can cause leaks or poor oil flow. Stop the engine immediately if the oil-pressure warning remains on, oil leaks from the housing, or abnormal engine noise starts after service.
Use only the housing parts and seals specified for your engine. Do not stack old and new O-rings, reuse a damaged seal, apply sealant unless the manual requires it, or substitute a similar-looking cartridge without confirming the dimensions and cross-reference.
Pros and Cons
Pros
- Verified cartridge dimensions make comparison with the old element easier.
- Includes the main housing O-ring needed for many installations.
- Cellulose/synthetic media supports routine powersports filtration.
- Built-in bypass relief valve is rated at 18 to 22 psi.
- Wide published fitment range across selected Honda, Kawasaki, Polaris, and Suzuki models.
Cons
- Vehicle-specific fitment leaves little room for guessing by brand or engine size.
- Marketplace descriptions may incorrectly call it a spin-on filter or claim an anti-drainback valve.
- The advertised 10,000-mile protection period may exceed the required interval for many powersports engines.
Is It Worth the Price?
The FRAM CH6015 sits in the practical replacement-filter category rather than the premium racing tier. Its value comes from verified specifications, broad cross-reference support, an included O-ring, and availability from a familiar filter brand. It is a smart buy when you service your own compatible machine and want one package for the element and main housing seal.
You get less value if you cannot confirm the part number or if your dealer service plan requires an OEM component. The purchase price is small compared with the cost of correcting an oil leak or lubrication problem, so fitment and proper installation matter more than saving a few dollars between filters.
How It Compares to Alternatives
The HiFlo HF112, K&N KN-112, and Wix 24944 appear as common cross-references for CH6015. The K&N option may appeal to riders who prefer that brand’s powersports line, while HiFlo is another widely used cartridge alternative. An OEM Honda, Kawasaki, or Polaris filter may be the better choice when you want the exact factory part number for dealer records or warranty confidence.
The FRAM makes the most sense when CH6015 is already listed for your engine and you want a conventional aftermarket cartridge with an included O-ring. Compare the actual package contents and fitment, not just the cross-reference number, because sellers may bundle seals or accessories differently.
Frequently Asked Questions
Is the FRAM CH6015 a spin-on or cartridge filter?
It is a cartridge-style filter element. FRAM’s part-specific page lists cartridge dimensions, an included O-ring, and no anti-drainback valve, even though some marketplace wording calls it a spin-on filter.
What vehicles use the FRAM CH6015?
FRAM lists many selected Honda and Kawasaki motorcycles, ATVs, and UTVs, plus certain Polaris Predator and Outlaw models and Suzuki DR-Z110 years. Fitment changes by model year, so confirm your exact vehicle in a current catalog before ordering.
Does the CH6015 include an O-ring?
Yes. FRAM lists one O-ring with a 2.094-inch inner diameter, 2.296-inch outer diameter, and 0.094-inch thickness. Check the package before starting the oil change and compare the new seal with the one removed from your housing.
Does this filter have an anti-drainback valve?
No. FRAM’s CH6015 specifications list no anti-drainback valve. The part does include a bypass relief valve rated at 18 to 22 psi.
Can I use synthetic oil with the FRAM CH6015?
Yes, FRAM states that Extra Guard filters work with conventional and synthetic motor oils, and the marketplace listing also includes blended oil. The oil still needs to meet your engine manufacturer’s viscosity and performance specification.
Can I leave the CH6015 installed for 10,000 miles?
FRAM advertises protection for up to 10,000 miles, but your vehicle’s oil-and-filter interval comes first. Many off-road and small powersports engines use shorter mileage, hour, or calendar schedules, especially in dusty or hard-use conditions.
What filters cross-reference with CH6015?
Common published cross-references include HiFlo HF112, K&N KN-112, Wix 24944, Kawasaki 52010-1053, and Polaris 3088036. Honda uses several related OEM numbers, so match the exact number listed for your engine rather than choosing from appearance alone.
What is the biggest installation mistake to avoid?
Do not leave the old O-ring in place, twist the new seal, reverse the cartridge, or tighten the housing by feel when the manual gives a torque value. After refilling, inspect the housing for leaks and confirm the oil-pressure warning goes out normally.
The Bottom Line
The FRAM Extra Guard CH6015 is worth considering when your motorcycle, ATV, or UTV specifically calls for this cartridge or a confirmed cross-reference. Its verified dimensions, included O-ring, cellulose/synthetic media, and bypass valve make it a practical routine-service choice.
Buy it when fitment is confirmed and you are prepared to follow the engine maker’s installation and service schedule. Skip it if your vehicle uses a different element, you need an OEM-only part, or you are relying on inaccurate spin-on and anti-drainback wording from a marketplace listing.
