What Makes the ACDelco PF2232 Different?
98% Multi-Pass Filtration Efficiency
One of the biggest selling points of the PF2232 is its stated 98% multi-pass filtering efficiency at 25–30 microns.
The filter uses cellulose filter media designed to capture contaminants before they circulate through the engine. According to the current Walmart listing, the media is capable of trapping particles described as approximately one-third the width of a human hair.
For normal oil-change intervals, this provides a good balance between filtration and oil-flow management.
Large Filter Design
The PF2232 is a relatively large spin-on filter, measuring approximately 5.35 inches tall and 3.67 inches in outside diameter according to current parts information.
The larger housing provides substantial filter-media capacity, making it a popular choice for applications that specify this filter.
However, size alone doesn’t mean the filter can be substituted for another filter. Always verify the exact filter specified for your engine.
Anti-Drainback Valve
The PF2232 includes an anti-drainback valve.
Its purpose is to help keep oil inside the filter when the engine is shut off. Keeping the filter primed can help reduce the amount of time required for oil to reach the engine’s lubrication system after startup.
Bypass Valve
The PF2232 also includes a bypass valve with a listed relief setting of approximately 11–17 psi.
A bypass valve is important because an oil filter must still allow oil to reach the engine when the filter media becomes restricted or when oil is especially thick during cold starts.
Strong Steel Housing
ACDelco lists the PF2232 with a 200 psi burst-pressure rating. The Walmart listing additionally describes the filter as having burst strength five times greater than typical engine operating pressure under the specified conditions.
This gives the filter a durable housing suitable for normal automotive operating conditions.
ACDelco PF2232 for Duramax Diesel Engines
The PF2232 is particularly popular with owners of GM trucks equipped with certain 6.6L Duramax diesel engines.
GM’s own service documentation identifies ACDelco PF2232 as the specified engine oil filter for certain 8-cylinder applications.
That makes the PF2232 especially interesting for owners who prefer using an ACDelco filter rather than switching to an aftermarket equivalent.
However, Duramax applications have changed over the years, and newer engines can use different filter part numbers. Always check the exact year, engine, and VIN/application before ordering.
Vehicle Compatibility
The PF2232 is used across a variety of applications.
Depending on the specific year and engine, it may be used on vehicles from brands including:
Chevrolet
GMC
Cadillac
Buick
Hummer
Isuzu
Other compatible applications
Walmart currently lists PF2232 applications including select 2001–2019 Chevrolet Silverado and GMC Sierra models, while other listings show additional compatible vehicles.
Important:
Do not purchase the PF2232 based only on the vehicle model.
The correct oil filter can vary by:
Model year
Engine
Engine displacement
Vehicle configuration
Production changes
Always verify the filter against your owner’s manual, VIN, or a trusted vehicle-fitment catalog.
PF2232 Filtration Performance
For a conventional spin-on filter, the PF2232 offers a strong combination of filtration and flow management.
Its stated 98% multi-pass efficiency at 25–30 microns means the filter is designed to remove a high percentage of particles within that test range over multiple passes through the filter.
It’s important to understand that a micron rating isn’t simply a statement that every particle larger than that size will be removed in a single pass. Multi-pass efficiency is a specific testing measurement.
For everyday driving and manufacturer-recommended oil-change intervals, the PF2232 provides a solid level of filtration.
PF2232 Installation
Installing the PF2232 is similar to installing most conventional spin-on oil filters.
Basic installation procedure:
Warm the engine according to the vehicle manufacturer’s service instructions.
Drain the old engine oil.
Remove the old oil filter.
Clean the filter mounting surface.
Check that the old gasket has been removed.
Apply a thin layer of clean engine oil to the new filter gasket.
Install the PF2232 by hand.
Tighten it according to the instructions supplied with the filter or the vehicle manufacturer’s specifications.
Refill the engine with the correct amount and grade of oil.
Start the engine and inspect the filter area for leaks.
Shut the engine off and recheck the oil level.
Never overtighten a spin-on filter. Excessive tightening can damage the gasket or make the filter difficult to remove during the next service.

ACDelco PF2232 vs. Cheap Aftermarket Oil Filters
One of the main reasons to choose the PF2232 is confidence in the manufacturer and application-specific design.
A cheap aftermarket filter may cost less, but price alone doesn’t tell you how well the filter media, gasket, bypass valve, anti-drainback valve, or housing will perform.
The PF2232 provides clearly stated filtration specifications and is available through major automotive parts retailers.
For a GM owner who wants a straightforward replacement filter without experimenting with unknown brands, the PF2232 is a sensible option.
What Do Buyers Say?
The Walmart listing currently shows the PF2232 with a 4.5/5 rating from 148 ratings.
Recent Walmart reviews include buyers praising its value and fit, with one reviewer specifically mentioning using the filter on a GMC Duramax for multiple oil changes without problems.
AutoZone’s current listing has the PF2232 at 4.8/5 from 116 ratings, with 97% of reviewers recommending the product.
These customer ratings are encouraging, although individual experiences should not replace checking the correct filter specification for your vehicle.
Is the ACDelco PF2232 a GM OEM Filter?
This can be confusing because different retailers currently describe the PF2232 slightly differently.
Walmart’s listing calls it the ACDelco Professional Engine Oil Filter, while AutoZone and NAPA identify the PF2232 as an ACDelco GM Original Equipment filter. NAPA also notes that some ACDelco GM Original Equipment parts may previously have appeared under the ACDelco Professional or GM Genuine Parts naming.
Therefore, when writing about this filter, the safest description is:
ACDelco PF2232 Professional Engine Oil Filter / GM Original Equipment application
rather than claiming that every PF2232 package is identical to a filter installed at the factory.
Is the ACDelco PF2232 Worth Buying?
Yes — if the PF2232 is the correct filter for your vehicle.
Its combination of 98% multi-pass filtration efficiency, large filter capacity, anti-drainback protection, bypass protection, and durable construction makes it a strong option for routine oil changes.
It is especially attractive to GM truck owners who want to stay with the ACDelco brand.
The biggest consideration isn’t whether the PF2232 is a good filter — it is — but whether PF2232 is the correct filter for your particular engine.
Final Verdict
ACDelco PF2232 Rating: ⭐⭐⭐⭐⭐ 4.7/5
The ACDelco PF2232 Professional Engine Oil Filter is a dependable, well-established oil filter with strong filtration specifications and a durable design.
Its 98% multi-pass efficiency at 25–30 microns, anti-drainback valve, bypass valve, large housing, and 200 psi burst-pressure rating make it a compelling choice for compatible vehicles.
For GM owners who follow regular oil-change intervals and want an ACDelco filter, the PF2232 is an excellent choice.
Our recommendation: Buy it when your vehicle’s manufacturer or fitment catalog specifies PF2232. Don’t substitute it solely because it is physically larger or because another filter looks similar.
