ACDelco PF48 Oil Filter 6-Pack — GM Original Equipment, OE Fit & Anti-Drainback

ACDelco PF48 Oil Filter (GM Original Equipment) — a six-pack of OE-fit filters engineered to trap contaminants, protect engine parts, and match factory specifications for many GM vehicles.

These ACDelco PF48 filters are replacement oil filters built to the same dimensions and performance criteria used by General Motors at assembly. Sold in a convenient 6-pack, they are designed for routine maintenance intervals and to provide consistent oil flow, reliable sealing, and filtration efficiency that meets or exceeds original equipment requirements. The PF48 is popular for its balance of filtration media, bypass protection, and anti-drainback features that help preserve engine life when used as directed.

Which vehicles and engines fit the ACDelco PF48?

The PF48 matches the original equipment specification for a range of GM models and select other vehicles that use the same filter footprint. Always cross-check with your vehicle’s owner manual or parts application to confirm fitment before purchasing.

• Common fitments include various GM cars and light trucks; check VIN or OEM part cross-reference.
• Designed to replace factory-installed oil filters with the PF48 designation.
• Suitable where the OEM requires a spin-on filter with these dimensions and thread size.

How does this oil filter protect my engine during normal use?

The PF48 removes solid particles and contaminants from circulating oil to reduce wear on bearings, rings, and oil passages. Its filter media and construction maintain oil flow at typical operating pressures while providing a clean oil supply to critical engine components.

• High-efficiency filter media captures fine particulates and soot.
• Bypass valve prevents oil starvation if the element becomes restricted.
• Anti-drainback features help preserve oil in the filter during shutdown for quicker lubrication at next start.

What should I know about installation and maintenance?

Installing the PF48 is a straightforward do-it-yourself job for most users with basic tools, but following proper steps ensures a reliable seal and correct torque. Replace the filter at the intervals recommended by your vehicle manufacturer or during each oil change.

• Lubricate the gasket lightly with clean engine oil before threading onto the housing.
• Tighten by hand to the manufacturer-specified torque or according to turn-after-contact guidance.
• Dispose of used oil and the old filter according to local recycling rules; many service centers accept used filters.

Why choose the ACDelco branded OE filter instead of an aftermarket alternative?

ACDelco PF48 is produced to original equipment dimensions and tested for compatibility with GM engine systems. Choosing an OE-design filter helps ensure predictable fit, consistent performance, and parts compatibility, especially for warranty-conscious owners and technicians.

• Manufactured to meet GM’s engineering and quality standards.
• Consistent materials and sealing reduce the risk of leaks or fitment issues.
• Sold in a 6-pack for cost-effective routine maintenance or fleet use.

Who is this for: The ACDelco PF48 (6 pack) is aimed at DIY owners, independent mechanics, and fleet managers who service GM vehicles or any car that specifies the PF48 replacement. It suits people who prefer parts that match factory specifications, expect consistent fit and filtration, and want the convenience of multiple filters for regular oil changes.
